The experiments which form the subject of the present communication were carried out two years ago, and supplement results already published. A brief note of some of the results was read before the Society in June 1904, and was also read before the British Association Meeting at Cambridge in August of the same year.

The previous paper discussed the effect of high temperature on the relation between electrical resistance and magnetization when the wire was magnetized longitudinally, that is, in the direction in which the resistance was measured.

The present results have to do with the effect of high temperature on the relation between resistance and magnetization when the magnetization was transverse to the direction along which the resistance was measured.

Archæologists and students of Roman Scotland have long known that somewhere in the neighbourhood of Newstead, near Melrose, lay the site of a Roman settlement.

Excavations which have recently been undertaken by the Society of Antiquaries of Scotland, under the direction of Mr James Curle, F.S.A., of Priorwood, Melrose, have been successful in ascertaining, to the east of the village of Newstead, the exact position of a large fort, which occupied a commanding position within sight of the Eildon Hills.

It is well known that double ovariotomy, when performed prior to puberty, exercises a prejudicial effect not only upon the generative organs but also upon the whole organism. There is, however, some disagreement as to the results of this operation when performed after puberty, and particularly in regard to the occurrence of heat or menstruation.

It is the purpose of this paper to adduce further evidence upon this question, as well as to describe experiments the result of which indicates that the nature of the ovarian influence is chemical rather than nervous.

The town of Ardrossan is built largely upon the 15-feet beach which to the north and south of the promontory is a well-marked terrace of sand and gravel, but on the promontory itself is represented by a rocky shelf rarely exceeding 12 feet in height. The promontory owes its origin to a great extent to the igneous rock of the Castlehill and the Inches, which has offered more resistance to marine denudation than the neighbouring sandstones. The railway to West Kilbride runs for some distance along the 50-feet beach, while the 100-feet beach is represented by an irregular accumulation of sand and gravel some distance inland.

In a Lepidosiren embryo of stage 20 (Graham Kerr) the mesoderm stretches continuously through the head and trunk regions. In the trunk the dorsal mesoderm is segmented into myotomes, but the segmentation stops short some distance behind the auditory vesicle, leaving unsegmented mesoderm in front of this. In both head and trunk the lateral plate mesoderm is still connected with the dorsal, myotomic or somatic portion.

In 1905 there was published an account of the Tardigrada collected in the Scottish Lochs by the Lake Survey (6). At that date we were able to name 21 species. The subsequent work of the Survey has enabled us to add a number of species to the list.

Moreover, the wanderings of the members of the Survey over every part of Scotland offered an excellent opportunity for the study of the whole Tardigrade Fauna. A recent journey to the Orkney and Shetland Islands added much of interest to our knowledge of Tardigrada, though few of the species found were lacustrine. The work of Mr Wm. Evans in the basin of the Forth has also added much of value to our records of Tardigrada (7), (10).

These notes on Arctic Tardigrada embody the results of an examination of quantities of moss collected by Mr William S. Bruce on his various expeditions to the Arctic Regions.

While studying the Tardigrada of the Scottish lochs, I wished to compare our Tardigrade fauna with that of more northern lands, as it was thought that, considering the geographical position of Scotland, its fauna might have some relation with that of those lands. Mr Bruce was kind enough to put all his available material at my disposal.

The first part of this work was published in the Transactions of the Society for 1905, when the present section was promised by the end of the same year. But the labour of revising the whole work on the sections and of posting all the muscles in the extensive series of key sections along with the skeleton has been much greater than was anticipated, and hence the delay. This labour, however, is amply repaid by the knowledge that one is now in a unique position for studying the blood-vessels and nerves; for not only has every fraction of the skeleton and muscles been microscopically explored, but the information obtained is immediately and completely available on reference to the key sections. When the whole work is completed and all the systems have been entered in these sections, I hope to obtain a grant to enable me to publish them as an atlas. As far as I am aware, no animal has been studied throughout in this way before.

The two new species of Osmundites described in this paper are based upon two fossils from the Jurassic rocks near Gore, Otago district, New Zealand. The one was discovered by Mr Robert Dunlop, and the other by Mr Robert Gibb. Both specimens eventually came into the possession of Mr Dunlop, who generously handed them over to the authors for investigation, with full permission to have them cut for microscopical examination, and to whom we take this opportunity of expressing our indebtedness.

In three memoirs published from time to time in the Transactions of this Society I have described the characters of the crania in several Asiatic races, the bulk of which were natives of India, though a few were from countries adjoining Hindostan. In this memoir I intend to continue my inquiries into the cranial characters of Asiatic people, and to give an account of natives of Borneo, the Malays, the natives of Formosa, and the Tibetans.

There were seven Turbellaria in the material handed to us by Mr W. S. Bruce, all obtained in April 1903 from Scotia Bay, South Orkney Islands (9–10 fms., Station 325, lat. 60° 44′ S., long. 44° 51′ W.). Their occurrence is interesting, as, although Studer (Ueber Seethiere aus dem Antarktischen Meere, 1876) mentions, without adequately describing it, a Eurylepta from Kerguelen Island, there are no definite records, so far as we have been able to ascertain, of Turbellarian species from nearer the Antarctic than the coasts of South America.

Among the numerous littoral Alcyonarians collected by the Royal Indian Marine survey ship Investigator in the Indian Ocean there are five small Siphonogorgids of exceptional interest and apparently new to science. As some time must elapse before the publication of the complete memoir on the Indian Ocean collection, it seems advisable to make a separate report on these new forms. In so doing, I must acknowledge my indebtedness to Professor A. Alcock, F.R.S., and Professor J. Arthur Thomson, M.A., F.R.S.E., University of Aberdeen, for the opportunity of studying these interesting forms, and to the latter also for much kind advice and encouragement.
