Case I. — The subjeet was a Fox-Terrier dog born and bred in this 
country and the property of a European gentleman. It was admitted into 
this hospital in a dying condition and died within 1/2 an hour after admis¬ 
sion. P. M. examination revealed Filaria immitis blocking up the right 
ventricle of the heart. 
Case II. — It was a cross-bred bull dog belonging to an Indian 
gentleman. The animal was admitted for treatment of mange and 
general dropsy. The main svmptoms were dullness, dépréssion and general 
debility. The animal was so week that it could hardly move or walk. Ana- 
sarcous swelling was found ail over the body. The excreta were normal. 
The dog did not appear to relish its food. Local treatment combined with 
internai administration of Pot. Ioçjide showed no improvement. On the 
4th. day after admission, the dog fell down and died immediately while 
being bathed. The autopsy revealed several interlaced Filaria in the right 
ventricle. The organ itself was very pale, flabbv and had gelatinous exuda- 
tion at the base. The muscular tissue looked lilce boiled méat. 
Case III. — The subjeet was an imported English Fox-Terrier dog, 
the property of a European gentleman. It was admitted into this Infirmary 
in a moribund condition for treatment of Epilepsy. The animal was very 
weak and emaciated. It used to hâve 3 or 4 fits daily. On the 4th day it 
dies suddenlv in succession of epileptic fit. Filaria immitis was discovered in 
the right auricle. 
Case IV. — The subjeet was an imported Fox-Terrier dog belonging to 
a European gentleman. This animal was admitted for treatment of distem- 
per. After a treatment for a period of fortnight, the dog developed paralvsis 
of hindquarters which became very much aggravated later on and the dog 
ultimately died in a very weak and emaciated condition at the end of the 
2nd fortnight. Autopsy showed Filaria immitis in the right auricle. 
The specimens are preserved in the Muséum of the Bengal 
Veterinary College.

MM. Railliet et Henry. — Dans la Revue vétérinaire du 
I er novembre 1912, Ganguly (i) vient justement de signaler trois 
observations de Filaria ( Dirofilaria) immitis à Calcutta. 
A quelques jours de distance la note de M. Mitter vient donc 
confirmer la présence au Bengale de cette espèce parasitaire. II 
semble d’ailleurs que certains des cas signalés dans les deux 
notes soient identiques. 
Mais la Filaire cruelle ne paraît pas devoir être incriminée en 
ce qui concerne le cas de dermatose vermineuse constaté par 
Mitter, en 1910, chez un chien. En effet, les embryons recueillis
