colon were enlarged ; the liver also showed upon its diaphrag¬ 
matic surface beneath the serous membrane covering the middle 
and right lobes numerous small hemorrhages; the liver acini 
were enlarged and clearly differentiated from one another ; the 
liver tissue was greyish yellow, the central veins contained 
hardly any blood, the consistency of the liver soft and friable. 
The spleen was enlarged, of a dark red color, of pretty firm con¬ 
sistency ; the Malphigean bodies were prominent and enlarged 
from the size of a bean to that of a hazel nut. The kidneys 
upon longitudinal section showed numerous small hemorrhages 
in the medullary layer. The pleura contained a tablespoonful 
of bloody serum, the pericardium a half a teaspoonful. The 
heart was markedly enlarged and in a condition of diastole, both 
ventricles containing blood, the right ventricle the most, the 
heart was dilated, the myocardium, especially of the right ven¬ 
tricle, being atrophic, the left ventricular wall being also thin¬ 
ner than normal; the valves showed nothing abnormal with the 
exception of a little thickening of the free- edge of the mitral 
valve, a change insufficient to cause either stenosis or insuffi¬ 
ciency ; the heart muscle was dry and of a greyish red color. 
The lung was retracted, dotted upon its dorsal aspect under the 
visceral pleura with numerous white nodules varying in size from 
that of the head of a knitting needle to that of a pea; upon 
scraping the lung tissue with the flat surface of the knife, a 
foaming fluid exuded. The bronchial and other lymphatic 
glands were enlarged, of a soft consistency, and of a greyish 
white color. The cerebral and spinal meninges showed numer¬ 
ous small hemorrhages. ' The marrow of the long bones was 
dark red and of a gelatinous consistency similar to juniper 
jelly ; the bones very, very fragile.—{. Berl . Thierarzt Woch.) 
Tannaebin as an Intestinal Astringent [Engel ].— 
For years chemists have been trying to find a preparation of tan¬ 
nin that would not be dissolved or absorbed in the stomach, and 
that would thus be able to exert its astringent effect upon the 
bowel. Tannigen meets these indications and has been used 
with good results. G. made use of the fact that egg albumen 
after long continued heating at high temperatures becomes 
nearly or altogether impervious to the action of the gastric juice. 
This statement applies to tannin albumenates. By tests it was 
established that heating for five to six hours at ioo° to 120° C. 
suffices to keep the egg albumen thus heated intact from the 
action of gastric juice for 24 hours, whereas the pancreatic 
juices digest it. The tannin albumenate tannalbin occurring as
