Amos Perry to William H. Seward, July 13, 1867

Mr. Perry to Mr. Seward

Sir: * * * * *

Since my last despatch the sanitary condition of this city has undergone several sudden changes, generally attributed to the direction of the wind. The desert wind, called the sheely,which is dry and hot, is regarded as healthy, and during its prevalence scarcely a case of the cholera is said to occur; while the cool and refreshing breezes whose presence ordinarily afford pleasure, bring on contagion and death. As an illustration, last Tuesday was as cool as an April day, but over 200 deaths by the cholera were reported; while yesterday we had a scorching sheely and not a case of the cholera was reported.

My attention has been called to many cases of partial insanity, induced by the fear of the cholera. One official personage in this city was thus rendered incompetent to discharge his regular duties. His spirit was darkened, and his powers of mind and body partially paralyzed. This effect, however, is said to be oftenest seen among females who pass their time in brooding over imaginary troubles.

Very respectfully, your obedient servant,
