44} TRANSLATIONS FROM CONTINENTAL JOURNALS. 
May. In the intestines of one of them were found 49 Tania 
ccenuri , varying from 55 to 70 centimetres in length ; and in 
the other 113 of the same worm, and of similar lengths. The 
third dog is still alive. He frequently voids proglottides, 
and, on the 18th and 20th of June, there were found in his 
excrements four entire taeniae, which presented all the cha¬ 
racters of the Tania ccenurus. 
In order that these experiments might attain their desired 
object, the author has experimented, at the same time, on 
lambs, kids, and calves, and even on an old cow, and a goat, 
six or seven vears old, although the ages of these latter 
afforded very little hope of success. 
The first experiment was on two lambs. They were given 
the proglottis taken from the dog Rigolette. The first had 
administered to him on the 10th of March, 1839, ten pro¬ 
glottides, and symptoms of vertigo manifested themselves 
suddenly on the 20th, and continued till the 23d of the 
same month. During the whole of that time the lamb con¬ 
stantly laid down on its right side, and when put on its 
legs it could hardly stand. Its gait was unsteady, and it 
always turned to the right whenever it could be made to 
walk a few steps. 
On an autopsia being made, the brain was found, on its 
upper surface, to be of a pale-yellow colour, and furrowed in 
a striking manner, resembling the traces left by the larvae 
of certain insects on organized matter which they have 
passed over. All the blood-vessels of the surface of the 
brain were much distended, and, on cutting into the sub¬ 
stance of that organ, it was observed to be marked with 
numerous red spots. In one of the furrows above described 
some vesicles were found of a spheroidal shape and trans¬ 
parent. 
On the 21st of May, the second lamb was given fifteen 
segments of the taenia taken from the intestines of some 
dogs that had been destroyed on the same day. 
The symptoms of vertigo had not long to be waited for. 
On the 30th, the animal was observed to be very dull, 
stood in a corner, and refused its food. On the 1st of June 
the head was evidently carried on the right side. There 
was also marked debility ; the cubitus was almost constant, 
and when made to walk a few paces the action of the limbs 
was unsteady. On the 3d the state of the animal indicated 
great suffering, and the head was rested against the wall, 
which it pushed at with all its might. The next day these 
symptoms continued, and ultimately they became more 
aggravated, until the animal died, which was on the 7th of 
June.
