The occurrence of this species in considerable numbers in this vicinity has afforded an opportunity for comparison with A. aphrodite, the results of which are appended.It should be stated that although the number referred to is small, yet the unrecorded comparison of over two hundred examples of both species during the past summer has agreed fully with this. In the line before me are five females each of alcestis and aphrodite. In every case the general color of the upper surface is duller in aphrodite, the basal shading heavier and more extensive, and the black markings on primaries heavier; in two examples the color approaches that of A. cybele, while the examples of alcestis exhibit a uniform clear color with hardly any variation.

In several previous communications we have described the investigations made by us on the dielectric constants of various frozen organic bodies and electrolytes at very low temperatures. In these researches we employed a method for the measurement of the dielectric constant which consisted in charging and discharging a condenser, having the given body as dielectric, through a galvanometer 120 times in a second by means of a tuning-fork interrupter. During the past summer we have repeated some of these determinations and used a different method of measurement and a rather higher frequency. In the experiments here described we have adopted Nernst’s method for the measurement of dielectric constants, using for this purpose the apparatus as arranged by Dr. Nernst which belongs to the Davy-Faraday Laboratory.

In my Paper read February 22nd, 1866, the intention was expressed of continuing my experiments on rigidity with a modified form of apparatus. This intention was carried out during the past summer, and I have now to report the results. In the former experiments, the rod operated on was supported at both ends, and was bent or twisted by hanging a pair of equal weights so as to act symmetrically on both ends; and the amounts of flexure and torsion were measured by the movements of two images formed by reflection upon a screen.

During the past summer Mr. F. W. Urich, Government Entomologist, Trinidad, B.W.I., succeeded in rearing a number of small Chalcids from larvae of a thrips in the prepupal stage. The following description is based on part of this material.

During the past summer numerous inquiries were received by Professor Elford, Dominion Poultry Husbandman, Experimental Farm, Ottawa, with regard to an apparently infectious disease appearing among ducks. So frequent and insistent were the appeals for aid in this connection that the co-operation of the Health of Animals Branch was requested. This resulted in an investigation being undertaken to ascertain the clinical nature of the disease; to demonstrate, if possible, the cause; and also institute measures for its prevention.

Although the phenomena of the Pyro-Electricity of Minerals, as it has been termed, and those of the Tourmaline in particular, have, after a long period of neglect, been recently studied by more than one philosopher of eminence, there are a sufficient number of undetermined or debatable points, even at the threshold of the inquiry, to yield facts of novelty and interest to those who will take the trouble to look for them.Having during the past summer been much engaged in studying the relations of bodies to heat and electricity, I was induced, by having in my possession a considerable number of long tourmalines, to repeat and endeavour to verify some recently published experiments with this mineral. These inquiries brought out several new facts; and, with the hope of adding something to our knowledge in this curious field, I have taken this opportunity of communicating to the Society the results of some very recent experiments.

Gheel is a well-worn theme on which it is hard to say anything that is very fresh. But circumstances of various kinds have of late contributed to renew general interest in this ancient settlement. The condition of lunacy affairs in our own country is somewhat fluid just now, and the insertion of any foreign object may help to bring about solidification. Finally, I had occasion to revisit Gheel during the past summer. On the whole, when I was asked for a paper for to-day it seemed not unsuitable that I should fall back upon this time-honoured topic.

A round, white, woolly gall was found on stems of Bigelovia (sp. probably graveolens)in several localities in western New Mexico the past summer, from June 19 to 22. Those found June 19 were old galls, and were met with near Luera Spring, in Socorro county. On June 21 the fresh galls were found in numbers near Gallo Spring. Sometimes two or three were found near each other on the same stem or twig of the plant, and in one case three galls were found joined together, forming a triple gall. On June 22 they were found extremely common west of Apache Spring, thus seeming to increase in number in a westerly direction, as did also the patches of Bigelovia, every plant of which was full of them.

The other day a distinguished artist friend of mine called upon me with a small bottle containing some whiskey, which by its odour I judged was good, when he first took it from his flask, and in it was what he denominated a “bug.” He told me that he had experienced “one of the most wonderful adventures of his life” in connection with the specimen he put before me, and went on to tell me that during the past summer, while sketching in the mountains, he had discovered one evening, when undressing, a small, dark swelling on his breast. He thought it to be a little abnormal growth on the skin and paid no attention to it. From time to time he noticed it afterwards, when retiring, and found to his considerable alarm that it was gradually growing larger, and evil thoughts of cancer, tumors, and what not, began to float through his mind. Finally, after some two weeks had passed, one evening, as he expressed it, “while fooling with the darned thing it came off” He laid it down on the dressing-case before him and was presently astounded to see it slowly crawling away from the spot. Then a small bottle was sought out, the whiskey flask was brought into requisition, and the “bug” was safely bottled, to be referred to me for an explanation. This proved not difficult to give. The specimen was a well-developed example of Ixodes albipictus, Packard. We had a hearty laugh together, and my friend assured me that he “would know better the next time, and not let such creatures establish such a lengthy abode upon his person.” His adventure recalled to me a letter which I have long had in my possession, intending to publish it, as it is very well written, and adds a touch of humour to the subject. The specimen referred to in the letter is in my collection, and proves to be an example of Ixodes bovis, a very common plague in the south-western part fo this country.
