ANALYSIS OF CONTINENTAL JOURNALS. 
This property is shown by mixing blood with glycogen 
solution and adding sodium glycocholate or ether to destroy 
the blood-corpuscles. It also acts as a ferment during its 
coagulation. Solid glycogen is not changed by the blood, 
its conversion occurring only when in solution. The author 
supposes that the conversion of glycogen into sugar in the 
liver is due to a destruction of blood-corpuscles taking place 
in its capillaries, the glycogen probably existing partly in a 
dissolved state, and being transformed in the capillaries 
rather than in the hepatic cells. This view is confirmed by 
an experiment which he made at Kuhne’s suggestion, in 
which he found that the glycogen taken up by water passed 
through the portal vein of a rabbit's liver became converted 
into sugar if blood were present in the liquid, but did not do 
so if the blood were completely removed. He distinguishes 
three kinds of diabetes. 1st. When the glycogen is not 
increased, but the destruction of blood-corpuscles is more 
rapid. To this class belong Harley's method of injecting 
chloroform, ether, alcohol, or ammonia into the portal vein, 
and the author's experiments, in which he occasionally suc¬ 
ceeded in producing diabetes by injecting very slowly J| 
c.c. of ether into the vein of the ear and repeating it at 
intervals. 2nd. When the glycogen is not increased nor 
the destruction of corpuscles more rapid, but more glycogen 
is dissolved in the liver. An example of this is the production 
of diabetes by injection of 1 per cent, salt-solution into the 
arteries. 3rd. Artifical increase in the amount of glycogen 
by injection into the vessels.—T. L. B .—Journal of the

THE CATTLE PLAGUE IN GERMANY IN 1870. 
The losses occasioned by the cattle plague in Germany 
in 1870 have been published in the official report of the 
Chancellor of the Empire, Prince Bismarck, presented at 
the third session of the German Reichstag. This report, 
however, does not include the losses among the cattle of the 
army commissariat parks, which must have been enormous.
