hydatid, farther than the holding of the head in the uniform di¬ 
rection from left to right in which she pursued her course. Sup¬ 
posing that the inner plate of the cranium might become softened, 
the frontal sinuses were interposed extending from the nasal bone 
to the foramen magnum, and the external plate would remain 
sound. Had she been in somewhat better plight, I am afraid that 
I should have at once consigned her to the butcher. 
I then reflected, that although these symptoms, this holding 
of the head on one side, and this circular motion, were the effect 
of pressure on a particular part of the brain, and in the sheep 
were produced by an hydatid, yet that effusion between the 
membranes, spreading over only a small surface, or the rupture of 
some minute vessel, might produce the same effect, and might 
possibly be doing so here : I determined therefore to give her a 
chance, and I bled her again freely, and from the left jugular, 
as the mischief, whatever it was, seemed to be on the left side; 
and I gave her another and a stronger dose of physic, and I had 
the pleasure of seeing her considerably relieved, and in less than 
a week she was perfectly well. 
French Accounts of the same Affection .—A twelvemonth after¬ 
wards I was gratified at meeting with a report of four cases of 
a similar kind in the Recueil de Medecine Veterinaire, by Pro¬ 
fessor Gelle, of Toulouse. The symptoms suddenly appeared : 
the appetite was diminished ; rumination ceased ; the faeces were 
voided in small quantities, and hard; the urine was thick, 
and the mouth was hot. The ox turned frequently, and con¬ 
stantly in one direction, and while he was turning he endeavoured 
to crop a few blades of grass. The conjunctiva was injected and 
red; a mucous discharge flowed plentifully from the nose; and 
the pulse was accelerated and hard. The horns and ears were 
hot; the hide adherent; and there was great tenderness over the 
region of the loins. M. Gelle considered it to be a slight cere¬ 
bral inflammation : he bled ; administered mucilaginous drinks, 
with Glauber’s salts, and put the animals on spare diet,—and in 
the course of four or five days the beasts were perfectly recovered. 
You will not therefore consider this turning as necessarily in¬ 
dicating the existence of an hydatid in the brain of cattle; but 
will rather attribute it to some temporary and local effusion or 
pressure, which bleeding and physicking and starvation may 
possibly remove. 
Hydatids have been found in the Brains of Cattle* —Cases, 
however, have occurred in which a disease marked by this pecu¬ 
liarity of turning has actually been produced by the existence 
of hydatids in the brain of cattle. Bartholin relates, that in 
1661 a great many beasts perished from a species of frenzy, and
