Letter of the Day: February 18

Major D.L. Huntington.
Washington, D.C.

Dear Sir:

I have this day mailed to you a microscopic specimen of some epidermas[sic] scales in a case I have diagnosed as chromophytosis.

This specimen was prepared after one application of chrysophanic acid and green soap according to Piffard in Wood's Library. I sought for the parasite withe[?] a 1/4 objective before any applications were made, but was unable to satisfy myself of its presence.

I regret that it did not occur to me to mount a slide before treatment was commenced. The slide is poorly mounted but represents the earliest specimen prepared.

To all appearances the disease which has existed since 1878 has entirely disappeared after five or six applications of the above treatment.

Will you have the kindness to forward me the results of your examination.

Very respectfully
Your obdt servt.
