diseases, and one in particular, “ Purpura haemorrhagica.” No 
misappropriated name ever led to so much error and confusion 
as this one. That rare and benignant disease of man, justly 
termed “ purpura,” is rare and benignant in the horse. The 
cases looked upon as purpura are often, I am certain, 
typhus, or very closely allied to it. 
Intermittent Fever in Horses and Cattle. — 
This disease has been so rarely witnessed in animals that its 
existence has been denied by some authors ; others have 
described, under this head, very different diseases or 
affections, having only some characters in common with 
true intermittent fever. Professor Joseph Lessona, of the 
Turin school, was, for many years, attached to a large 
breeding establishment in Sardinia, and in a long memoir 
on marsh emanations, he speaks of the frequency of inter- 
mittent fever in cattle, horses, and even sporting dogs, not 
only in Sardinia but in Turin and the Roman marshes. 
Lessona says that it is only through inattention that it has 
not been observed in cattle. He has had occasion to show 
it to his colleagues and students, presenting a quotidian or 
quartan type. The treatment consisted in cinchona bark, 
and quinine. — Turin Veterinary Journal , p. 291, 1854. 
Lehwer, speaks of a case of intermittent in the horse. 
For eight days consecutively the horse had attacks of 
shivering, followed by heat, and this associated with 
depression and disturbed appetite. During the attack, the 
pulse was small and rapid, the respiration short, the spine 
stiff, the region of the spleen sensitive and expanded ; after 
the shivering had lasted about a quarter-of-an-hour the 
heat set in. Besides a small bloodletting, Lehwer prescribed 
potassio-tartrate of antimony in decoction of chamomile; 
the next attack was weaker, and then all symptoms subsided, 
and the animal recovered. — Supplement to the Magazin fur die 
ges. Thierheilkunde for 1855. 
Genuine intermittent undoubtedly occurs in animals, and 
I have good reason to believe that it is to be observed in the 
jungles in India. So far as Europe is concerned, and Great 
Britain in particular, the evidence of its existence has not 
been clear till recently. Ruini speaks of it, but he is not a 
great authority on pathological questions. Lanini alludes 
to it as associated with similar organic lesions ; viz., enlarged 
spleen in man as in animals. Cleghorn speaks of hyper- 
trophied spleen the result of ague, as very frequent amongst 
the sheep in the Island of Minorca. Royston alludes to 
intermittent affections in the horse in the marshy districts
