INFLUENCE OF CLIMATE, ETC., ON THE DISTRIBUTION & CHARACTER OF DISEASE.

value, mules largely predominate, and as a rule they are not so 
well fed and cared for as in other sections considered. 
Dr. Kilbourne, Washington, D. C., has found the disease 
quite prevalent in the District of Columbia, Maryland, and Vir¬ 
ginia, usually in a mild chronic form. 
Under rigid sanitary laws the disease has decreased in the 
District of Columbia from y8 cases in i88p to one case every 
month or two. He has noted one case of spontaneous recovery 
from nasal glanders, two from Farcy, all proven cases of glan¬ 
ders and the recovery from one year after disease seemed in 
every way complete.

Dr. Cary, Auburn, Ala., comparing glanders in Alabama 
with his observations in Iowa and Illinois, finds the disease more 
virulent in the former state, owing to increased humidity with 
heat. 
Dr. W. B. Niles, Ames, la., who has observed the disease in 
South Caiolina and Iowa, finds that in mules it runs an acute 
course, while in horses he notes no difference in South Carolina 
and Iowa. 
Dr. Tait Butler, Agricultural College, Mississippi, reports 
the disease rare in his state. Prof. A. W. Bitting, Florida, re¬ 
ports that in Florida isolated cases are rare and acute in form. 
The diseased animals, if not already in their ownership, are soon 
transferred to negroes. 
Along the low, and more humid sections of the Pacific Coast 
glanders of a virulent type prevails quite extensively. 
Aside from some very small areas, we have briefly glanced 
over the United States, except the Rocky Mountain region, and 
the high and to a great extent arid plains, sloping from their 
base towards the Mississippi River, a large part of which is cold, 
some of it extremely so, all quite dry, even to converting much 
of it without irrigation into a great desert, the altitude varying 
from 2,000 to 8,000 feet, and horses kept generally in large 
bands without stabling. They are usually placed in such envir¬ 
onments as permit, with labor, the procuring of a liberal, if not 
an abundant supply of food.
