lantic, the next county to the north, till December 1. Its general pro- 
gress was southward and westward, yet not without some perplexing 
anomalies. In Ohio, for instance, it appeared about October 1; in 
Geauga, in the extreme northeast, and in Hamilton, in the extreme 
southwest, while in the majority of the counties of the State its advent 
is reported as late in November, and in one—Williams, in the extreme 
Northwest—so late as December 20. In the other States north of the 
Ohio River, its first symptoms were variously noted from the middle of 
October till Christmas. West of the Mississippi it appeared to radiate 
about equally in different directions. At our latest advices it had just 
appeared in Lewis and Clarke County, Montana, and in Ada County, 
Idaho; in both localities its introduction was charged upon overland 
stage companies, It appeared in El] Paso County, Colorado, as early as 
December 1; but Conejos, Huerfano, Douglas, and Weld report its 
appearance in the earlier part of January. Still later it appeared in 
Santa Fé County, New Mexico, and in Sevier, Weber, Tooele, Rich, 
San Pete, Cache, and Davis Counties, Utah. Its presence was felt in 
Plumas County, California, as early as December 1; in Alameda, De- 
cember 15; Santa Clara, January 31; San Joaquin, February 14; Alpine, 
March 5; Los Angelos, March 18. It was expected in other counties 
in California, Oregon, and Washington, but in the latter it had not 
appeared. 
The average dates of the first appearance of the disease in each of 
the States were as follows: Maine, October 19; New Hampshire, Octo- 
ber 20; Vermont, October 18; Massachusetts, November 7; Rhode 
Island, November 1; Connecticut, October 29; New York, October 19; 
New Jersey, October 20; Pennsylvania, October 24; Delaware, October 
28; Maryland, October 22; Virginia, November 5; North Carolina, 
November 17; South Carolina, November 19; Georgia, November 23; 
Florida, November 17; Alabama, December 1; Mississippi, November 
28; Louisiania, December 5; Texas, December 17; Arkansas, November 
19; Tennessee, November 21; West Virginia, November 19; Kentucky, 
November 18; Ohio, November 9; Michigan, November 2; Indiana, 
November 19; Illinois, November 17; Wisconsin, November 15; Minne- 
sota, December 3; Iowa, November 28 ; Missouri, December 7; Kansas, 
December 10; Nebraska, December 14. 
The symptoms of the disease are detailed with remarkable uniformity 
in different parts of the country. It is everywhere described as a 
catarrhal influenza; in many places it so closely resembles the old fash- 
ioned “distemper” that, but for the special attention given to the subject, 
it would have been identified with it. That it is to some extent conta- 
gious seems scarcely to admit of doubt, but this character of the malady 
will by no means account for its regular and rapid extension over the 
country. It traveled in radial lines from its original points of develop- 
ment in the New England and Middle States, and within ten weeks was 
demonstrating its existence in Texas and California. Its local diffusion 
was accompanied by phenomena which cannot be accounted for upon 
the hypothesis of contagion. Its appearance at points in advance of its 
_ regular line of progress, and its simultaneous development in all parts of 
a county, argue the existence of some general conditions, some predispos- 
ing causes of disease, developing themselves in succession like waves 
across the continent. In New York City 40,000 horses were attacked 
within a week or ten days, and in all the cities, towns, and rural districts, 
the visitation was so sudden and so general as to paralyze all kinds of 
transportation which depended upon the use of horses. Occasionally 
horses would escape the disease, though confined in stables with infected
