produced vertigo in the sheep would also produce it in other 
ruminants ; that is to say, in the ox and the goat. 
Of all the tribe Ruminantia, the sheep is the one that is 
most commonly attacked with vertigo, and although it is 
less frequently seen in the goat, nevertheless, many vete¬ 
rinary surgeons have had opportunities of observing it in 
those animals: but it is infinitelv rarer in the ox. However, 
M. de Siebold informs us that in Southern Germanv a great 
w 
number of the ox tribe are attacked with this malady. M. 
Prince has also stated, in the Journal clu Midi , that it is fre¬ 
quently met with in the Jura Mountains of France. 
But it is not only ruminants that are exposed to the 
ravages of the coenuri, they have been found in the rein-deer, 
the camel, and the roebuck. M. P. Gervais has met with 
them in a mouflon at Montpellier, M. de Blainville in a cha¬ 
mois at the museum in Paris, and the author assisted at the 
autopsia of a gazelle at the Veterinary School of Toulouse, 
in the cranium of which an enormous coenurus existed. 
Whatever may be the animal in which they are found, 
they are always in the form of vesicles, having semi-trans¬ 
parent parietes, their size varying with their ages, and on their 
surfaces scolices more or less numerous exist. These external 
appearances are, however, not sufficient to establish, without 
further proofs, that, in the different kinds of ruminants, the 
coenurus found in them belongs to the same zoological spe¬ 
cies ; and it can only be by experiments, and the study and 
comparison of the scolex of the one and of the other, that it 
can be hoped to solve this question. 
Many of the proglottides were collected from the faecal 
matter of the bitch, Rigolette ; the only one that remained 
alive of those to whom the coenuri had been administered 
in 1858. It may be as well to remark here that it was more 
than sixteen months since, that a portion of a coenurus had 
been given to Rigolette, and although not a week passed 
without finding a proglottis, or fragments of several seg¬ 
ments cf the taenia, her health did not appear to be at all 
impaired by the presence of these parasites in her intestines. 
But it might be presumed, that had she been employed as a 
shepherd’s dog, it would have occurred to her owner to have 
kept her from the flock, or she might have fearfully spread 
the seeds from which vertigo is derived. She was not, how¬ 
ever, the only dog from which the author obtained the pro¬ 
glottides for his experiments. Others were furnished by three 
young dogs, to which,on the 2d and 25th of February, 1859, 
had been given two coenuri, found in the brain of two lambs 
that had been slaughtered on account of their being affected 
C # 
with vertigo. Two of these dogs were killed on the 21st of
