fection, inasmuch as their tissues are but little adapted to the 
emigration of the proscolex of the cesto’idea. 
These experiments may be summed up in the following 
manner: 
Three dogs took, at the same time, portions of the coenuri 
obtained from the brains of two sheep, and in all three the 
taenia ccenurus was found in their intestines. 
2. To two lambs was given the proglottis of the taenia 
coenurus, and both fell a sacrifice to vertigo ; and in the 
brain of them were found a certain number of coenuri and 
other serious alterations in their great nervous centre, caused 
by the proscolex. 
3. Four kids were likewise made to swallow the proglottis 
of the taenia, and although the results were negative in two of 
them, the congestion of the brain in the third must be attributed 
to the invasion of the proscolex. And as to the other, the 
existence of numerous coenuri in the brain suffices to estab¬ 
lish the complete success of the experiment. 
4. To a calf was given, like the preceding ruminants, the 
proglottis of the taenia coenurus, and at its death twenty-four 
coenuri were found in its cranium. 
5. An aged cow and an old goat were subjected to the 
same test, but they remained healthy ; this, however, might 
have been foreseen on account of their age. 
The result is, that in twelve animals experimented on, 
eight have confirmed in a most positive manner the repro¬ 
ductive function of the cesto’idea. But this conclusion is not 
the only one derived from these experiments ; for, as before 
stated, the microscopical examination of the scolex detached 
from the coenurus of the sheep, the goat, and the ox, allows, 
as a fair presumption, that it is the same species of the order 
Cesto’idea which gives rise to vertigo in these different ani¬ 
mals. In fact the proglottisides and the segments which were 
administered to these ruminants, were all derived from coenuri 
that had existed in the brain of sheep. As for the dog 
Iligolette and the others, it was by making them swallow the 
coenuri of sheep, that the taeniae coenuri were produced in 
the intestines of these carnivora. If, therefore, the eggs of the 
taeniae have produced the coenuri in the brain of the calf and 
kids, it cannot be doubted that these cvsticerci are the 
same as those of the sheep, since they are derived directly 
from the coenuri taken from the cranium of the sheep. 
We are therefore justified in drawing the following infe¬ 
rences from these experiments: 1. That the eggs of the 
taeniae coenuri in sheep will also produce them in the goat 
and in neat cattle. 2. That, consequently, these three 
hydatids, although they existed jn three different species of
