ten days. From Skagway the parties went 

 by rail to Whitehorse Eapids, and thence by 

 steamer to Eagle, on the Upper Yukon. From 

 this point Mr. Prindle is to make his way to 

 the southwest, visiting the placer gold fields 

 of the Fortymile region. Mr. Gerdine will 

 begin topographic work, extending a survey 

 across to the new gold district on the Lower 

 Tanana, which Mr. Prindle will examine later 

 in the season. 



At the meeting of the Zoological Society 

 of London on July 16 it was announced that 

 the diving birds' tank and the fish-house would 

 be finished within a month, and the new large 

 aviary on the south bank of the canal in 

 August. Six loose boxes are being erected 

 on the north bank for the accommodation of 

 some of the valuable collections of Equidae now 

 in the gardens. The work of re-roofing and 

 restoring the eastern and western aviaries had 

 been undertaken. The erection of a suitable 

 building for the accommodation of keepers 

 had been sanctioned and plans were being 

 prepared. The plans for new cages for the 

 birds of prey had been prepared and passed, 

 and the contracts were being arranged. The . 

 erection of a new house for small mammals 

 had been decided upon. Plans of the most 

 recent buildings of this nature had been ob- 

 tained from continental gardens and the 

 erection of the buildings would be forthwith 

 undertaken. 



A Keuter telegram from Berlin says that, 

 according to the National-Zeitung, Professor 

 Kossel, of the Imperial Health Office, has read 

 a paper at a meeting of the Berlin Medical 

 Society upon the results of the work done by 

 the Tuberculosis Commission in connection 

 with the investigations made by Professors 

 Koch and Schuetz. Professor Kossel summed 

 up the results of a series of experiments as 

 proving that tuberculosis in the human being 

 can be communicated to cattle, and vice versa. 

 The practical question — namely, which com- 

 munication was more frequent and how great 

 was the danger attaching to it — remained, 

 however, still undecided. The results of the 

 experiments, which consisted of the inocula- 

 tion of calves with human tuberculosis by 



subcutaneous injection, tend to support Pro- 

 fessor Koch's view that the bovine tuberculosis 

 bacillus is of a different species from that of 

 human tuberculosis. A definitive opinion on 

 the point is, however, reserved fo. the result 

 of a further series of experiments in which 

 inoculation will be made by means of feeding 

 and inhalation. 



The report of the council of the Marine 

 Biological Association of the United King- 

 dom for 1902-1903, as summarized in the 

 London Times, states that the work of the 

 council has this year been considerably aug- 

 mented in consequence of the fact that a com- 

 mission has been accepted from his Majesty's 

 government to carry out in the southern 

 British area the program of scientific fishery 

 investigations adopted by the International 

 Conference which met at Christiania in 1901. 

 The share of the international program under- 

 taken by the association includes a scientific 

 survey, by means of the steamship Huxley, of 

 the trawling grounds lying between the east 

 coast of England and about 3° 30' E. longi- 

 tude. The Huxley began her fishing work on 

 November 1. Up to the middle of June the 

 Huxley had completed twelve scientific trawl- 

 ing voyages in the Xorth Sea. Over 34,000 

 fishes have been measured, the majority being 

 flat fish. The animal life of the bottom has 

 been systematically studied from the point of 

 view of distribution, and the food-contents of 

 about 3,000 fishes have been examined and 

 determined. In the investigation of the plaice 

 nurseries near the Horn Eeef in May Ht. 

 Garstang was joined on board the Huxley by 

 the distinguished superintendent of the Danish 

 investigations, Dr. C. G. Joh. Peterson. Op- 

 portunity was thus afforded of repeating in- 

 vestigations on some of the same stations 

 which had been explored by the Danish vessel 

 Thor six weeks earlier. The comparison of 

 results revealed certain changes in the dis- 

 tribution of fish in the interval, which were 

 further investigated with definite and interest- 

 ing results. Plaice have been marked and 

 liberated in various parts of the area south 

 of the latitude of Bridlington. In November 

 and December last the first experiments were
