PITYRIASIS IN THE HORSE, &c. 
By AIM. Marly and Causse, Veterinaires du lime Chasseurs. 
For some time past diseases of the skin have been the 
subject of long, laborious, and minute investigations by the 
medical profession. Those labours have served to guide the 
observer and the practitioner in the adoption of a rational 
therapeutic treatment, but undoubtedly all has not been 
done; there remains still a great many morbid states to be 
unveiled which, with the assistance of micrography, may be 
brought within our knowledge. In veterinary medicine, 
proceeding by analogy, endeavours have been made to bring 
these observations to bear on the maladies of the cutaneous 
system of the animals, but the greatest confusion as yet pre¬ 
vails on this point. Thus, to quote only one example in 
Hurtrel d'Arboral and the authors who have preceded him, 
we find at the word dartres a definition very little in har¬ 
mony with what we now understand by herpes, which 
Willan has classed among the vesicular diseases, and Alibert 
among the dermato-eczematose. It is easy to perceive that 
under this name are comprised several different affections, 
the denominations of which belong to time long passed. The 
affections which the authors observed on some of the horses 
of the remounts which were purchased in the north and the 
south of France, and which were mostly of a dark colour, 
and from four to five years old, were thus distinguished. They 
presented on the surface of the body several spots denuded of 
hair, principally about the head, the top of the withers, the 
flanks, and the inside of the thighs, &c. When the patients 
were brought to the infirmary the malady had a well-defined 
character, the affected parts were of various sizes and shape, 
the depilation in the majority of them was almost complete, 
in others a few hairs remained. The scales were whitish, 
and were easily detached from the skin; there was a slight 
pruritus ; this symptom was, however, not constant, and in the 
majority of cases w r as so little marked that it might have
