STREPTOCOCCI IN COMPARATIVE PATHOLOGY. 
787 
ures however they appeared in long chains, leaving the liquid 
clear, as described by Sehiitz. 
This streptococcus did not grow in gelatin,'or serum, or on 
potato. It would not develop in acid media. On agar the colo¬ 
nies were small and characteristic of streptococci, i. e ., with a 
thickened convex grayish centre surrounded by a thin, spread¬ 
ing, bluish border, nearly equal in width to the diameter of the 
central portion. It fermented dextrose, lactose and saccharose, 
with the formation of acids but no gas. Milk remained un¬ 
changed in appearance. 
In mice and rabbits it produced a rapidly fatal septicaemia, 
but guinea-pigs were unaffected. A horse inoculated in the 
pleural cavity with a small quantity of the culture from case 
No. 3 was killed io days later. At the point of inoculation and 
extending over an area equal to one-half of the lung there were 
strong adhesions between the lung and parietes. The sub¬ 
jacent lung tissue was hepatized. Pure cultures of the strepto¬ 
coccus were obtained from the exudate and from the hepatized 
lung. 
Although a few discrepancies exist between the description 
of Schiitz’s organism and the streptococcus which I have found, 
they are not sufficient to warrant the opinion that they are dif¬ 
ferent species. In the essential features they seem to be iden¬ 
tical. The cases were examined before the publication of 
Eigniere’s results, and the methods I employed did not meet 
the requirements of those used in isolating his cocco-bacillus. 
Although a very careful histological study of the pneumonic 
tissue was made, Ligniere’s organism was not detected. At the 
first opportunity his methods will be tried.

Dr. Thomas L. Rice, assistant inspector of the Bureau of 
Animal Industry, who was stationed at El Reno, O. T., last 
quarantine season, has been transferred to the meat inspection 
department and ordered to report to Dr. A. J. Payne at Cincin¬ 
nati.
