The larvæ of this Noctuid moth were again found at Ottawa the past season, in beds of Irises, on the grounds of the Central Experimental Farm. They were not, however, at all numerous, and did not do any appreciable harm this years. Two larvæ were collected on July 28, one of which was inflated; the other pupated on Aug. 1, the moth emerging on Sept. 7. Another larva was found on Aug. 4, the moth appearing on Sept. 15. The pupa of the former specimen was much larger than any of those obtained in 1903, an account of which appeared in the last Annual Report of the Entomological Society of Ontario. This pupa measured 30 mm. in length and 7.5 in width.

Among the Tenthredinidæ captured by me during the past season was a good series of Tenthredo delta Prov, consisting of 12 females and 26 males. In pinning them I was frequently struck by the evident irregularity of the venation of the wings, and on a more careful examination of the specimens I find these irregularities to be both numerous and remarkable. No other species represented in my cabinet show any such divergencies from the typical form, except in rare instances. Provancher describes the female (page 210, “Petite Faune Entomologique du Canada”) as having two discoidal cells in under wings, and Cresson (“Trans. Am. Ent. Soc.,” vol. viii., page 44) as having one or two middle cells. One middle cell appears to be the rule, and any deviation therefrom to be an exception. Of my 12 specimens, 10 have one middle cell each, one has two middle cells, and the other none. The males are more uniform apparently in their venation, as none of my 26 specimens have middle cells in the under wings, thus agreeing with the description given by Cresson (loc. cit). Apart from the varying number of middle cells, the under wing of the females have the cells varying much in shape, especially the middle one, which ranges from a small triangular form to a large foursided (square or irregular) one. There are also occasionally small additional cells on the posterior margin.

Although my collections hitherto have been chiefly of Coleoptera, I have, as opportunity offered, captured specimens in other orders, and among those thus taken during the past season are representatives of a few species of the Uroceridæ. I wish now to record a few brief notes on these—the more readily, because so little regarding this group has been published in the Entomologist.1. On the 25th of June last I captured upon a recently dead maple tree, near my house, two rather small insects, of which the larger had its ovipositor inserted in the bark. They proved to be two female specimens of Xiphydria albicornis Harris. One was half an inch long, the other five-eighths.

An interesting contribution by Dr. FJetclrer, entitled “Entomological Record, 1901,” has just appeared in the 32nd Annual Report of the Entomological Society of Ontario. This, besides giving a list of the active workers in Canada, includes careful notes on rarities, etc., taken during the year. It is the intention of the Society to continue this Record from yeart to year, and as this will undoubtedly prove useful to entomologists throughout Canada, it is hoped that collectors in the dominion will try to make it as complete as possible. Records of interesting specimens captured, either from the standpoint of distribution or rarity, will be acceptable, and should be sent to Dr. James Fletcher, Central Experimental Farm, Ottawa. Specimens unknown to collectors will gladly be identified.

Tombs of all periods were opened during the past season, a few archaic ones at Leontari Vouno, which have been described by Mr. James in his account of that site, and others at Kuklia of all subsequent ages, down to the very latest. They are usually cut in the rock or earth of a gentle slope, in many cases, as in the Xylino valley at Kuklia, tier above tier: but they are also found in level ground, approached by a sloping passage now filled with earth. The whole plateau to the east of Kuklia above the is honey-combed with earth-tombs of this kind, consisting mainly of one or two vaulted chambers, leading one out of the other, without niches for the bodies, and entered by a vaulted opening closed by a slab. Such are probably tombs of the poor: the richer Cypriotes were for the most part laid in rock-tombs, such as abound in the plain north of New Paphos, and were found by us at Old Paphos on the slopes between the Temple of Aphrodite and the sea. From their greater durability and accessibility the latter were often used two or three times over, being sometimes sanctified at last for Christian burial by innumerable crosses, cut over the niches, as is the case at Cape Drepano: thus they are usually less profitable to the explorer of to-day than the earth-chambers, which were left undisturbed in the possession of their original tenants, and were not so easily detected by the τυμβωρύχος of the early centuries of our era. Of the work of the latter we found ample evidence at Kuklia: tomb after tomb was opened on the eastern slopes, in which broken glass and pottery were lying in a huge heap either in the middle or near the door, what the thieves did not want having apparently been wantonly destroyed: the lids of the sarcophagi were either hewn in pieces or wrenched aside, and even, in some cases, in order probably to evade notice, carefully replaced in statu quo. The door was by no means the favourite place of ingress, for we often dug down to find the slab quite undisturbed, while the tomb was in the state described above, and search would reveal the presence of a hole or passage cut through the solid rock from above or at the side.

Work carried out during the past year is described in the usual ICRC report.The 1968 Annual Report is divided as previously into two parts: practical, and general and permanent activities. The former deals with various countries and continents. Emphasis is laid on efforts made for victims in the Nigerian conflict and relief data showed their increasing extent. On the other hand, some of the specialist services, such as the Central Tracing Agency in Geneva, the International Tracing Service at Arolsen, the Medical Personnel and War Disablement Sections have continued to be particularly active. One has only to quote the Central Agency which in 1968 received 54,783 communications and sent out 54,227 items, a considerable increase in volume in comparison with the previous year.

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).

Image shifts in out-of-focus dark field images have been used in the past to determine, for example, epitaxial relationships in thin films. A recent extension of the use of dark field image shifts has been to out-of-focus images in conjunction with stereoviewing to produce an artificial stereo image effect. The technique, called through-focus dark field electron microscopy or 2-1/2D microscopy, basically involves obtaining two beam-tilted dark field images such that one is slightly over-focus and the other slightly under-focus, followed by examination of the two images through a conventional stereoviewer. The elevation differences so produced are usually unrelated to object positions in the thin foil and no specimen tilting is required.In order to produce this artificial stereo effect for the purpose of phase separation and identification, it is first necessary to select a region of the diffraction pattern containing more than just one discrete spot, with the objective aperture.

This paper explores Arnold Schoenberg’s curious ambivalence towards Haydn. Schoenberg recognized Haydn as an important figure in the German serious music tradition, but never closely examined or clearly articulated Haydn’s influence and import on his own musical style and ethos, as he did with many other major composers. This paper argues that Schoenberg failed to explicitly recognize Haydn as a major influence because he saw Haydn as he saw himself, namely as a somewhat ungainly, paradoxical figure, with one foot in the past and one in the future. In his voluminous writings on music, Haydn is mentioned by Schoenberg far less frequently than Bach, Mozart, or Beethoven, and his music appears rarely as examples in Schoenberg’s theoretical texts. When Schoenberg does talk about Haydn’s music, he invokes — with tacit negativity — its accessibility, counterpoising it with more recondite music, such as Beethoven’s, or his own. On the other hand, Schoenberg also praises Haydn for his complex, irregular phrasing and harmonic exploration. Haydn thus appears in Schoenberg’s writings as a figure invested with ambivalence: a key member of the First Viennese triumvirate, but at the same time he is curiously phantasmal, and is accorded a peripheral place in Schoenberg’s version of the canon and his own musical genealogy.

Countries with positive per capita real growth are characterised by positive national savings—including government savings, increases in government investment, and strong increases in private savings and investment. On the other hand, countries with negative per capita real growth tend to be characterised by declines in savings and investment. During the past several decades, Kenya’s emerging economy has undergone many changes and economic performance has been epitomised by periods of stability, decline, or unevenness. This article discusses and analyses the record of economic performance and public finance in Kenya during the period 1960‒2010, as well as policies and other factors that have influenced that record in this emerging economy.

Concepts of near-natural forestry are in great demand these days. Most German forest administrations and private forest enterprises attach great importance to being as «near-natural» as possible. This should allow them to make the most of biological rationalisation. The concept of near-natural forestry is widely accepted, especially by conservationists. However, it is much too early to analyse how successful near-natural forestry has been to date, and therefore to decide whether an era of genuine near-natural forest management has really begun. Despite wide-spread recognition, near-natural forestry is jeopardised by mechanised timber harvesting, and particularly by the large-timber harvester. The risk is that machines, which are currently just one element of the timber harvest will gain in importance and gradually become the decisive element. The forest would then be forced to meet the needs of machinery, not the other way round. Forests would consequently become so inhospitable that they would bear no resemblance to the sylvan image conjured up by potential visitors. This could mean taking a huge step backwards: from a near-natural forest to a forest dominated by machinery. The model of multipurpose forest management would become less viable, and the forest would become divided into areas for production, and separate areas for recreation and ecology. The consequences of technical intervention need to be carefully considered, if near-natural forestry is not to become a thing of the past.
