Die Parasiten der Infectionskrankheiten. 15 
a finely granular appearance when in mass. The red blood cor- 
puscles when examined immediately after removal from the body, 
where shriveled and crenated, without artificial provocation, as 
represented at bb Plate I. In one case many of the discs appea- 
red to have lost a portion of their substance, as if a circular piece 
had been punched out, the addition of water failing to restore the 
dise to its completeness. In one specimen only the white blood 
corpuscles were in great excess and aggregated in masses. The 
liquor sanguinis was invariably of a vellower colour than natural 
and contained minute yellow flocculi or flakes of granular matter 
of irregular size and shape as represented at cc Plate No. 1. After 
a clot had formed the serum was found to present a yellow tinge, 
due to a diffused coloration. The source of the yellow coloration 
was indicated by the occasional presence in the serum, after stan- 
ding for several hours, of rhomboidical — notched plates, such as 
were found also in the bile and consisted probably of cholesterine. 
In several instance, defibrinated blood, or serum poured from a 
clot, which originally abounded in corpuscles, was found after a 
few hours to be absolutely devoid of the latter, complete. disso- 
lution of the red discs having taken place long before putrefaction.“ 
In dieser Schilderung fällt namentlich zweierlei auf: Erstlich 
die runzelige und gekerbte (shrivelled and crenated) Beschaffenheit 
der rothen Blutkörper, ohne dass diese künstlich hervorgerufen 
wäre (without artificial provocation), und zweitens die Zerfliess- 
lichkeit der Blutkörper. Diese zweite Eigenschaft hat das Blut 
der kranken Rinder mit demjenigen der Hundswuth, welches ich 
untersuchte, gemein, die erste mit dem Blute der meisten, wo 
nicht aller Infectionskrankheiten. 
Herr Professor Stiles berichtet ferner: 
„Ihe specimen of portal blood.abounded in white blood cor- 
puscles, and in morbid cellular elements from the parenchyma of 
the spleen. 
2) The bile. The bile was, in all the cases which fell under 
my observation, abundant, distending the gall bladder to its ut- 
most capacity, filling the hepatic duct, and constituting the prin- 
cipal portion of the contents of the small intestines. Instead of 
presenting the normal greenish or brownish transparency, it was 
opaque, thick and grumous, nor was its capacity lost on filtration. 
It contained granular flakes and masses of a brillant yellow or 
orange tint to transmitted light, reddish brown on the filter by
