practically all translations from foreign languages and in most 
cases very meagre in detail and inaccurate in many important par¬ 
ticulars. From such as exist, however, I have not hesitated to 
draw freely whatever seemed of value, and acknowledge with 
pleasure the assistance derived from Dr. Fleming’s very able and 
exhaustive treatise in his “ Veterinary Sanitary Science and Po¬ 
lice,” from which, although differing radically from him in some 
important particulars, I have not hesitated to copy or condense the 
general history of the disease and his table of synonyms, and in 
nearly every part of the work have freely drawn whatever seemed 
of value to my purpose. 
I acknowledge also with pleasure many kind and valuable sug¬ 
gestions regarding the work by Prof. Law and Dr. Casewell.

HISTORY AND GEOGRAPHICAL DISTRIBUTION. 
The earliest account of the disease known is that by the Ger¬ 
man veterinarian Ammon, who witnessed it in 1796 and 1799 
amongst stallions and mares in Trakehnen, North Prussia, where it 
persisted until 1801 and reappeared six years later ; hut the disease 
was probably known at a much earlier date in southern Russia. 
It appeared in Austria in 1815 and in Hanover in 1816, where it 
spread and prevailed until 1820-21. In 1821 it appeared in 
Syria and Silesia, reappearing in the latter country in 1826. 
From 1827 to 1830 it caused great mortality in Bohemia, and 
in 1830 the disease appeared in Berne, Switzerland. From 1833 
to 1836 the disease raged in upper Silesia and again in the same 
province in 1840-41. Horse breeders had now become so 
thoroughly alarmed that careful investigation by veterinarians and 
severe legislative enactments soon checked the ravages of the 
disease in Germany. 
In 1847 Signol saw the disease in Algeria, where it caused a
