tion terminated. The eastern and western branches meet at 
Ponk-san-poon; the western branch is the largest and is said to 
rise inthe Kanti-country. There seems to be no doubt that there 
is no longer any reason to suppose the Irrawaddy is connected 
with the Sanpu river of Tibet———The Academy says there are 
several expeditions preparing to visit the Obi and Yenisei gulfs 
this season. M. Siberiakoff is fitting out sledges to take supplies 
to two of his vessels which have been frozen up in the Gulf of 
Obi during the winter. The steamer Wordenskidld will sail for 
the mouth of the Yenisei from Gothenberg. A hydrographic 
expedition is also being formed in Russia to visit the Sea of Kara 
and Gulf of Obi. 
MICROSCOPY." 
Tue Broop 1x Hisernation.—In the autumn of 1879, Professor 
V. Wittich, received twelve living German moles (Mus montanus ), 
in order to investigate the amount of glycogen in the liver during 
their winter sleep. One animal was killed accidentally immediately 
after its arrival, and the results obtained on a microscopical examina- 
tion of the blood, led to an examination of the blood of the other 
animals, all killed in perfect health, and in all the same appearances 
were found. One of the animals had died on the journey without 
signs of disease, although perhaps in consequence of a bite from 
another animal. 
The blood taken from a vein in the peritoneal cavity contained 
a large number of thread-like moving objects, which move the 
as decomposition sets in and the putrefaction-bacteria appear. 
They were very numerous, ten or twelve being found in every 
number of parasitic organisms may exist in the blood without 
causing any disturbance to the general health. Attempts were 
made to inoculate guinea-pigs, but in every instance with a nega- 
tive result—London Lancet.
