SUMMARY OF CURRENT RESEARCHES RELATING TO 
gelose the colonies are roundish, humid, and yellowish. Gelatin is 
liquefied. On potato the growth is abundant, and yellowish or greyish 
in colour. The optimum temperature is 38-40°. The organism, which 
is strictly aerobic, is extremely pathogenic to rabbits and pigeons, and 
the local manifestations after subcutaneous injection present a certain 
resemblance to the tropical ulcer. 
Streptococcus of the Aleppo Boil.* — Drs. M. Nicolle and Noury 
Bey have isolated a Streptococcus from nine cases of Aleppo boil, and they 
are of opinion that this organism is a specific one, partly on the ground 
that it is uninfluenced by antistreptococcus serum, and partly from find- 
ing it in all the cases examined, and thrice in a pure condition. There 
is nothing specially characteristic from a morphological point of view. 
On most media the cultures are typical and abundant. Milk is always 
coagulated. It does not thrive on potato. To animals it is only slightly 
virulent ; for on the average 2 ccm. of a bouillon-serum culture 48 hours 
old, at 37°, takes 10 days to kill a rabbit weighing 1500 grm. 
New Infectious Disease of Cattle.f — Dr. G. Bosso describes a dis- 
ease of cattle, which was diagnosed from the most prominent symptoms 
as either an acute infectious nephritis or acute infectious myelitis, and 
which belongs to the class of haemorrhagic septicaemias. The chief 
morbid appearances were ecchymoses, great enlargement of the spleen, 
and acute nephritis. Bacteriological examination of the spleen and 
blood showed the presence of oval bacteria with rounded ends and central 
constriction. The bacteria are motionless, 1*5/4 long and 0*5-0 *8 /x 
broad ; but in the kidney they are often 2 * 7 /x long. They stain easily 
with the usual dyes, and also with Gram’s method. On gelatin which 
is not liquefied the colonies are small, round, sharply defined, and of a 
greyish-yellow hue. On glucose agar the bacteria grew well. Meat- 
broth with glucose and glycerin soon became turbid, and much gas 
was produced. In milk the bacteria developed freely, but the medium 
was not coagulated. On acid potato the development was slight, but 
on alkaline potato the growth was luxuriant and of a yellowish-brown 
colour. Animals (guinea-pigs, rabbits, mice) inoculated with cultures 
died. Histological examination of the kidney showed the presence of the 
bacteria in the lymphatic and blood-vessels, and that profound changes 
had occurred in the Malpighian glomeruli. 
Effect of Intravenous Injection of Tuberculous Caseous Matter .| 
— Dr. N. Bosa injected two series of rabbits (15 and 10) with sterilised 
caseous matter obtained from tuberculous lymphatic glands. In the first 
series the caseous material was sterilised in an autoclave, in the second 
by passing it through a Chamberland filter. In both series the results 
were entirely negative, the injected material being apparently quite 
innocuous, and having none of the toxic effects displayed by sterilised 
cultures of tubercle bacilli.
