Letter to Harvey Cushing from Minis Hays, American Philosophical Society, 104 South 5th Street, Philadelphia, Pennsylvania, USA. Hays does not believe that Osler attended the International Congress of Medicine at Philadelphia in 1876. He suggests that Cushing consult the original registration manuscript kept in the Library of the College of Physicians in Philadelphia.

Letter to Harvey Cushing from Thomas McCrae, 1627, Spruce Street, Philadelphia, Pennsylvania, USA. McCrae was told by the College of Physicians in London that Osler became a Licentiate of the College in 1873. He then took the College examination and was given membership in 1878.

Letter to Harvey Cushing from Thomas McCrae, 1627, Spruce Street, Philadelphia, Pennsylvania, USA. McCrae draws Cushing's attention to the animal parasite, "Sphyranura Osleri," named after Osler. This was written about in the Journal of Morphology, Vol. I, No. I, September 1887.

Letter to Harvey Cushing from Thomas McCrae, 1627, Spruce Street, Philadelphia, Pennsylvania, USA. McCrae remarks that Osler often used the title M.R.C.P. (Member of the Royal College of Physicians), as he did on a paper entitled, "Notes of Intestinal Diverticula," in the Annals of Anatomy and Surgery, 1881, IV, #5, November. Osler and Allbutt were elected Fellows to the College in 1883. Allbutt delivered the Gulstonian [sic] Lecture in 1884. McCrae will send an account of a dinner for MacAlister in which much is said of the formation of the Royal Society.

Letter to Harvey Cushing from Thomas McCrae, 1929, Spruce Street, Philadelphia, Pennsylvania, USA.

Letter to Harvey Cushing from Francis R. Packard, 302, South 19th Street, Philadelphia, Pennsylvania, USA. Packard thanks Cushing for returning his letters from Osler and hopes that they were of some use. Osler's Foster review was published in the American Journal of Medical Sciences 1902, but Packard is not sure of the exact issue. He regrets that he does not have any of Osler's letters to his brother, Fred Packard.

The founders of the American Anthropometric Society were Dr. Harrison Allen, Dr. Joseph Leidy, Dr. William Pepper, Dr. Edward Spitzka and Dr. Dercum. The first meeting was held in 1899 and Osler was a member. The brains collected by the Society were kept in the Wistar Institute and studied by Dr. Spitzka. His findings were published in the Transactions of the American Philosophical Society, N.S., Volume XXI, Part III. [See CUS417/78.21] Incl. ms. notes.

Letter to Harvey Cushing from Henry H. Donaldson, Wistar Institute of Anatomy and Biology, Philadelphia, Pennsylvania, USA. Donaldson informs Cushing that the President of the Anthropometric Society is F.X. Dercum. The chief object of the society was the preservation of the brains of its members; Osler's name did not appear among the list of members. However, Donaldson does recall seeing Osler at a meeting of the Society at the Art Club in Philadelphia in 1890. Donaldson will send a copy of Osler's "Leaven of Science," which he delivered at the opening of the Wistar Institute.
