that some such plan as this might be adopted ; but we would 
not urge its adoption in preference to the system of regis¬

EXPERIMENTS ON THE PRODUCTION OE VERTIGO IN THE 
SHEEP, OX, GOAT, &c. 
By M. C. Baillet, Professor, Imperial Veterinary School, Toulouse. 
Since the remarkable researches of the Belgian and 
German naturalists have drawn the attention of the scienti¬ 
fic world to the migration and metamorphoses of the Ces- 
toi'dea, other interesting and multiplied experiments have 
confirmed the discoveries first made, and no one among 
those who have studied this division of zoology can doubt 
the reality of the principal facts upon which are based the 
new theories. But if the general laws which preside over 
these phenomena are at present well understood, it is not 
so with a multitude of secondary questions, the study of 
which is bound up with the habits of each particular 
species, and the solution of which offers on that account 
the greatest interest for the etiology of certain vermicular 
diseases. 
In a work, published nearly twelve months ago, the author 
has endeavoured to demonstrate, by microscopic research, 
that several species of the order Taenia, closely connected 
with one another, can inhabit the intestines of the dog, and 
that each of them corresponds to a particular hydatid. 
Further, that probably to this circumstance must be 
attributed the non-success of some experimenters, who, to 
produce vertigo in sheep, have made use of segments of the 
taenia of the dog. 
In the experiments which the author instituted this year, 
he proposed to ascertain whether the same species which
