NEMATODA IN NEW-BORN WHELPS. 
Not unfrequently it happens that just before death the 
entozoa will commence to migrate and make their escape by 
the bowels and mouth of the puppy, often entangled in a 
quantity of frothy matter. The nematodes are found of all 
sizes, the largest being about one and a half to two inches 
in length, and about the circumference of ordinary bell 
wire. 
Preventive measures .—In India to keep imported dogs in 
health is no easy task, but I know of no measure so effec¬ 
tive as the giving of 01. Ricini Tinct. Rhei, Spt. .zEther 
Nit. et 01. Tereb. once a week, in an aperient dose. In 
the case of pups, if they have administered once weekly a 
small quantity of 01. Ricini. with a few T minims of 01. 
Tereb., there will he little or no fear of their digestive system 
becoming filled with these entozoa. 
The early existence of nematodes in animals, conjoined to the 
case of tasnia in the new-born infant, is a scientific nut to 
crack; but I think the fact becomes greatly simplified by Dr.R. 
T. Lewis’s discovery of nematodain the blood of man, which, 
through the great kindness of that gentleman, I have had the 
pleasure of witnessing the existence of under the microscope. 
The young nematodes were making giratory movements in a 
field of blood which had been obtained by pricking the finger 
of a hospital patient. Since the actual nematode worm has 
been demonstrated in the blood, it leaves but little doubt 
but that ova may also be carried into the blood channels, and 
be deposited in certain parts and there developed. I hope to 
show from certain premises that in my opinion the Filaria 
oculi of the horse is developed in the eye from ova. 
[The facts observed with regard to the early existence of 
nematode entozoa in puppies in India have their counterpart 
in England. We cannot, however, so readily determine, 
as our correspondent has done, upon their true source of 
origin. With regard to nematodes within the blood-vessels, 
they also are common enough in the young ass and colt and 
some other animals. The museum of the Royal Veterinary 
College is rich in such specimens ; and it may now be said 
to contain—by the addition of Dr. Cobbold’s splendid collec¬ 
tion—the largest number of entozoa of any similar institution 
in Europe.— Eds.]
