ASCARIDES IN THE PANCREAS OF A PIG. By Railliet and Morot. 
Pancreatic parasites have been only exceptionally men¬ 
tioned either in man or in animals. Among these, echinococci 
are very rare in man as well as in ruminants ; cysticercus 
cellulosas have been found in men and in dogs; the scleros- 
toma equinum has been quite frequently found in the pan¬ 
creas of horses ; the ascaris lumbricoides has been found ex¬ 
ceptionally in man. No observation has ever been recorded 
of the presence of ascarides in the pancreas of animals. 
At a recent post-mortem made of a pig that had died with 
apoplexy an ascaris scilla was found in a dilated duct of the 
pancreas, into which it had evidently penetrated in passing 
through the canal of Wirsung.— Ibid. 
MORPHOLOGICAL STUDY OF FAVUS. By Constantin and Sabrazer. 
The authors have studied the characters of favus in men, 
dogs and fowls. They have determined as to the presence 
of three favuses of three different species. That of man and 
the dog closely resemble each other, but are distinguished by 
the constant appearance of the cultures and by the invariable 
structure of the mycelium and its coloration. The favus of 
fowls is entirely different, forming a special kind.— Ibid. 
MICROBIC ACTION OF DIGESTIVE SECRETIONS UPON THE BACIL¬ 
LUS OF KOCH—TRANSMISSION OF TUBERCULOSIS BY FAECAL 
MATTERS. By Cad sag and Bournay. 
Does the normal gastric juice act and destroy the bacillus 
of tuberculosis? The experiments of Wesener, Miller, Bol¬ 
linger and Hirschberger seem to confirm it affirmatively, 
while Strauss, Wurtz, Flack, Baumgarten, Fisher and Zagari 
have shown that the microbicide action of the gastric juice 
is very doubtful, at least concerning the bacillus of Koch. 
The experiments of the authors show its inefficacy and cor¬ 
roborate the opinion of the last experimenters. The results 
they have obtained authorize them to affirm that dogs and 
pigeons which eat tuberculous mixtures become centers of in¬ 
fection and true disseminators of the bacillus of Koch, most 
commonly through its lodgement in stables, barns and fields. 
These experiments prove the necessity of burying the tuber¬ 
culous substances to prevent their being eaten by dogs .—Ibid
