Letter of the Day: October 11

No 201 W. Franklin St
Baltimore Oct: 11 1887

Surgeon J.S. Billings U.S.A.

My dear Doctor

Having had remarkable success with a recent artificial crystallization of Cystine I send by present mail a new slide of the beautiful but very rare substance.

It was obtained from a lady who had septicemia after a 6 month’s miscarriage, although there can be no relation of causation in its pathological state.

Hoping that you are well – and thanking you for vol. VIII of Index I remain

Yours very sincerely
Christopher Johnston

I have the honor to inform you that I have this day sent, by mail, to the Army Medical Museum, one half doz microscopic specimens, prepared by myself. I desire that they be examined and that I may be notified whether they are properly mounted. If they are found worthy of a place in the microscopic section of the Museum I would be glad to have them placed there.


I am Sir,

Very respectfully

Your obedient Servt.

Letter of the day, March 9

Arthur Hill Hassall's work in public health led to reforms in water purity and to the Food Adulteration Act of 1860 in the UK and subsequent laws against the practice. Woodward may have gotten the title of his book wrong. It might be Food and Its Adulterations. Woodward, this letter's author, was a pioneer in photomicroscopy. Henry, its recipient, was head of the Smithsonian. The history of federal American food quality control begins a decade after this letter was written.

March 9, 1875

Professor J. Henry.

Respectfully returned. Beautiful plates of the microscopical appearances of various kinds of milk can be found in the Atlas of the "Cours de Microscop[i]e," of A. Donné, Paris, 1845, Plates XVII, XVIII, and XIX, and very good woodcuts, with an excellent account of the subject, in the article on "Milk and its adulterations," in Arthur Hill, Hasslin [Hassall] "Adulterations Detected," 2nd Edit, London, 1811, p. 205.

Very respectfully,
J.J. Woodward
