It is natural that arithmetic should have been the first mathematical subject to appear in print in the American colonies. It is, on the contrary, surprising that algebra should occupy over one-third of the space in the third book on arithmetic published in this country1 when nearly sixty years were to elapse before the appearance of another book2 containing any algebra. Some forty-five hundred titles3 of publications in Pennsylvania before 1785 show many almanacs but few works on mathematics, and none containing algebra. A complete bibliography4 of all American books up to 1792 reveals, among those on mathematics, only three which include algebra in their contents. One of the three is a Dutch text-book and while the extent of its influence was probably very limited, it has interest as the earliest and, for a long period, the only work on algebra printed here.

This book is a practical manual for the prescriber rather than a text book. The first chapter usefully explains pharmacological terms which are used later in the book. This is followed by three sections concerned with choosing drugs. The first section gives a list of ‘best buys’ for common complaints, the second looks at treatment policies and the third gives basic pharmacological information to help in making choices. Side-effects and drug interactions are presented in the next two chapters in a readily accessible form. The final chapter, called ‘Cautions,’ has some useful information not readily found elsewhere including data on teratogenesis and shelf-life of formulations. It also suggests which drugs we should stop using, and discusses factors to consider before using a new drug.

During the long period embraced in the present Retrospect, the most important incident that has happened in the philosophical circles of this country is the death of Professor T. H. Green, of Oxford—a man who for many years had been silently acquiring, not only by his power of thinking but by his strong and blameless personal character, a marked position and a unique influence among the leaders of thought in England. His philosophical position would perhaps best be defined by saying that he became the chief of that small, but notable, band of speculative students, centred mainly in Oxford, Glasgow, and Edinburgh, who are reviving the spirit of the systems of Kant and Hegel, in its application to the new scientific, political, and religious problems of the day. His distinguishing characteristics were his modesty and his earnest sense of duty—qualities perhaps not so conspicuous as they might be amongst the better known of modern psychologists. His modesty was such that he never assumed that he had mastered the secret of any writer, until he had bestowed the most extravagant labour and thought in exploring difficulties and obscurities on which the man himself had probably never bestowed a second thought. His earnestness was so thorough that he believed it to be merely his duty to struggle with the fundamental questions of the Sphinx of modern criticism, and find for himself and others not a negative but a constructive answer, no matter what toil and trouble it might cost. For he held that those who contribute, as we all in some way do, to the formation of public opinion upon the vital subjects of life and conduct, are under a terrible responsibility if they mislead their neighbours, or even if they refuse by sloth or vanity or cynicism that healthy guidance which their own attainments would enable them to give. These remarks are suggested by the fact that the first article of the April number of “Mind” is from Prof. Green's pen. Indeed it is one of the last pieces of work he ever personally sent to press; although we are glad to know that the groat Ethical work on which he had long been engaged is left with his philosophical friends in so complete a form that it will be published immediately. The April article is the second of three essays on the question, “Can there be a natural science of man?” of which the third holds the leading place in the July number. The scope of the essays, as well as of the “Prolegomena to Ethics,” to which they were in a sense introductory, will be best indicated if we quote a note added in the July number by Prof. Green's literary executor, Mr. A. C. Bradley.

Abstract. Nowdays, english as a subject learned in primary school level. Its because the important of english towards the student. This study was conducted aimed to know the influence of Picture Cards in teaching vocabulary to the third grade of Nida Suksa School, Thailand. The subjects of the research were students in the third grade. The researcher only took nine students in different abilities from a high level (3/1), middle level (3/2), and low level (3/3). The instrument used by the researcher was an interview. The result showed that the students still had difficulty in understanding the texts because of having a lack of vocabulary, long texts, and limited time to analyze the text in answering the question. The students studied vocabulary through Picture Cards, and they learned vocabulary tests from text book. Furthermore, the finding of this study was: Picture Cards is able to increase and enrich their vocabulary and their knowledge. The implication of Pictures Cards can motivate students to understand the text. Therefore, they can understand many texts in vocabulary tests.Keywords: Teaching Vocabulary, Picture Cards

During the course of investigations of maternal red cell volume, employing transfusions with radioactive iron, an opportunity was afforded to measure the persistence and utilization of iron transferred across the placenta to the infant. A wealth of fundamental data was obtained concerning the importance of iron obtained from the mother in hematopoiesis during infancy. As the donors' cells containing radioactive iron which were transfused during pregnancy were broken down, radioactive iron was released into the general supply of the mother and fetus. At birth the blood of each infant contained a measurable ratio of radioactive iron to packed red cells. The ratio of radioactive iron to hemoglobin and to hemoglobin iron could then be calculated. Further calculations gave information concerning the amounts of hemoglobin iron of transplacental and dietary origin. The results indicated that there was little or no utilization of dietary iron for hemoglobin formation by the infants until 3 to 4 months after birth. Incorporation of the radioactive iron obtained transplacentally into hemoglobin during the growth of the infant indicated that normal infants utilize iron obtained during fetal life throughout infancy. Data from infants followed for a long period suggest that after 3 to 4 months dietary iron continues to be added to transplacental iron for the production of hemoglobin and gradually begins to replace transplacental iron in hemoglobin formation during the third year.

Infectious diseases are the leading cause of death worldwide and the third leading cause in the US. Among these maladies are many that can be classified as emerging diseases. Some of these disorders may be caused by truly novel pathogens. in others, the causative organisms have been present for many years (for some, probably millennia), but have escaped detection until recently. Still others represent the re-emergence of known pathogenic organisms after a long period of quiescence. The mention of emerging pathogens brings to mind sensational exotic and feared microorganisms such as Ebola virus, human immunodeficiency virus (HIV), hantavirus, West Nile virus, Yersinia pestis (plague), and prion diseases such as bovine spongiform encephalitis (BSE, “mad cow” disease) which have been associated with variant Creutzfeldt- Jakob disease (CJD) in humans. However, other organisms that have been known for some time can be classified as emerging pathogens as they continually mutate, recombine, and adapt, causing misery and death.


The author had pointed out, in a paper published in the Philosophical Transactions for 1828, on the corrections of the elements of Delambre’s Solar Tables, that the comparison of the corrections of the epochs of the sun and the sun’s perigee, given by the late observations, with the corrections given by the observations of the last century, appears to indicate the existence of some inequality not included in the arguments of those tables. As it was necessary, therefore, to seek for some inequality of long period, he commenced an examination of the mean motions of the planets, with the view of discovering one whose ratio to the mean motion of the earth could be expressed very nearly by a proportion of which the terms are small. The appearances of Venus are found to recur in very nearly the same order every eight years; some multiple, therefore, of the periodic time of Venus is nearly equal to eight years. It is easily seen that this multiple must be thirteen; and consequently eight times the mean motion of Venus is nearly equal to thirteen times the mean motion of the earth. The difference is about one 240th of the mean annual motion of the earth; and it implies the existence of an inequality of which the period is about 240 years. No term has yet been calculated whose period is so long with respect to the periodic time of the planets disturbed. The value of the principal term, calculated from the theory, was given by the author in a postscript to the paper above referred to. In the present memoir he gives an account of the method of calculation, and includes also other terms which are necessarily connected with the principal inequality. The first part treats of the perturbation of the earth’s longitude and radius victor; the second of the perturbation of the earth in latitude; and the third of the perturbations of Venus depending upon the same arguments.

This paper describes the results of a study on the influence of two rather different factors on the quality of a translation: L2 proficiency on the one hand and familiarity with translation theory on the other. Three groups of Dutch university students were asked to translate a French advertisement text on tourism into their first language: two groups (students of French studies en students of German studies) attended the translator's training programme; the third group studied only French. The model for translation quality assessment used here is based on a functional concept of translation: a translation is an independent text functioning in the target culture. The analysis revealed that students from the first two groups, who had reflected on translation processing, had better results than the third group: they made less functional errors beacause they were trained in taking the function of the translation into account and produced a Dutch text that was more adequate. L2 proficiency had only a secondary positive effect on the translation.

Abstract Due to poor ecological status of Lake Starzyc, lake restoration measures were undertaken in 2003 to improve aerobic conditions of near-bottom waters and to decrease phosphorus concentrations. To do this, a wind-driven pulverising aerator was installed in the lake. The aim of this study was to analyse variability of oxygen and nitrogen concentrations in lake water near the aerator in the third year of its operation and later on in the three-year-long period of the years 2008–2010. It was found that concentrations of ammonium-nitrogen, nitrate-nitrogen and dissolved oxygen near the aerator did not differ from those in sites 4 and 5, which evidenced similar abiotic conditions in analysed waters. Higher concentrations of dissolved oxygen and lower concentrations of nitrate-nitrogen were found in the years 2008–2010 than in 2005.

The circular Sitnikov problem is revisited, using matched asymptotic expansions. In the case of large oscillation periods, approximate analytical expressions for the period and the orbit of the third body are found. The results are compared with those described in the literature and show that the movement of the third body can be well described by two analytical solutions, the inner and outer solutions.

Seasonal changes in the concentration and dynamics of phosphate–phosphorus were studied in two small lakes, one oligotrophic and one artificially eutrophied. Because the molybdate blue phosphate technique frequently overestimates phosphate concentrations, three radiochemical assays were used. One, involving sephadex fractionation, was unsatisfactory because of the long period required for high molecular weight phosphorus fractions to reach isotopic equilibrium. The second method was unusable both for epilimnion waters within the Experimental Lakes Area, because of its low sensitivity, and for hypolimnion waters, due to interference from nonphosphate compounds. The third method, Rigler's bioassay, indicated that PO4-P in both lakes seldom exceeded 0.1 μg∙L−1, even under anoxic conditions. Organisms, and not mineral reactions, appeared to regulate the phosphate concentration at all depths in the lakes.Key words: phosphorus dynamics, orthophosphate
