loo NATURAL SCIENCE. Feb., 



The teaching organisation of the College of Science is, like that 

 of all the others, very complete. In the subjects with which we are 

 concerned the professors and lecturers are as follow, — in Zoology, 

 Professors Kakichi Mitsukuri and Isao Ijima ; in Botany, Professor 

 Jinzo Matsumura and Assistant-Professor Saburo Okubo; in Geology, 

 Professor Bunjiro Koto and Assistant-Professor Yasushi Kikuchi ; 

 in Palaeontology, Professor Matajiro Yokoyama ; and in Seismology, 

 Lecturer Fusakichi Omori. Physiology may appear a curious 

 omission, but this is amply provided for in the College of Medicine. 



The chief buildings of the University, including the offices, 

 the Library, the Colleges of Law, Medicine, Engineering, Literature 

 and Science, the First Hospital of the College of Medicine and the 

 Dormitories of the Colleges, are situated in somewhat park-like 

 grounds in the north of Tokio, which formerly belonged to the great 

 Daimyo, or Lord, of Kaga. The buildings connected with the 

 Natural Science Schools contain admirable laboratories, workrooms 

 and museums, through which I was shown, with great kindness, by 

 Professors Mitsukuri and Ijima. 



The Museums that now concern us are two : the Zoological, and 

 the Geological. 



The Zoological Museum, which is under the direction of Professor 

 Mitsukuri, is contained in one large room on the first floor. It con- 

 tains not only specimens, dissections and models, intended for the 

 instruction of the students, but also valuable collections of types 

 described by graduates and professors, and a large amount of material 

 from the lands and seas of Japan, that will be placed, as occasion 

 offers, in the hands of those students who wish to take up some 

 original investigation for the purpose of obtaining their doctorate. 

 Hitherto many of the groups constituting the Japanese fauna have 

 been worked out by Europeans ; but it is hoped that in future this 

 will be accomplished by the Japanese themselves. Among the notice- 

 able collections in this room is one of the parasitic worms of Japan, 

 which contains the types of Ijima and the specimens of Tristomum 

 now being described by Goto. Here is exhibited a specimen of 

 considerable human interest, namely a fine Bothriocephalus latus. 

 This tape-worm was well-known to exist in Japan, and indeed 

 caused great trouble in many districts ; but its source could 

 not be ascertained. At last Professor Ijima thought he had traced it 

 to a fish called Masu ; but the only way in which he could prove that 

 the parasite infesting that fish was indeed the larva of Bothriocephalus, 

 was by swallowing it. The experiment was successful. Twenty-two 

 days afterwards the full-grown worm was obtained, and it now graces 

 the shelves in the Museum of that University of which its erstwhile 

 host is still a living ornament. Another fine collection is that of 

 the Japanese birds, which is very complete and contains the types of 

 Ijima and Stejneger. The collection of fish is also unusually good, a 

 fact which is easily accounted for by the very various kinds of fish
