Letter to Oskar Klotz from William Osler, From the Regius Professor of Medicine, Oxford, Oxfordshire, England. Thanks for his paper. The "Arterial lesions in Rheumatic Fever" is particularly interesting. Glad to see the work progressing rapidly in Pittsburgh.

Letter to Oskar Klotz from William Osler, 13, Norham Gardens, Oxford, Oxfordshire, England. Sends him his article as requested. Pittsburg will give him a great opportunity for studying the effect of hard work and alcohol on the blood vessels. Suggests finding the incidence of syphilis among the men in the big steel works. Civilities.

Letter to Oskar Klotz from William Osler, From the Regius Professor of Medicine, Oxford, Oxfordshire, England. Suggests he look over the old books of plates at the Surgeon General's library to find many relating to lesions of the arteries. Baillie's Plate IV figures 2 and 3 are excellent. The Cevailliere is also good. Doubtful if Harvey's anatomical plates have been photographed. Suggests he make an historical collection of the cardio-vascular literature. He should request the help of a wealthy Pittsburgh man for the specific purpose. Marburgh, one of the Hopkins Trustees, has just handed over the money to buy the Jonathan Hutchinson Iconography. Advises him to begin with a copy of Harvey's "De Motu Cordis". Could easily obtain the permission to photograph the Harvey plates if it has not been done. Glad that he is interested in Lobstein. Civilities.

Letter to Oskar Klotz from William Osler, 13, Norham Gardens, Oxford, Oxfordshire, England. Thanks for the papers. Shows particular interest in his endarteritis about the orifices of the intercostals. Wilks, Moxon, and himself mention it too. Glad that he is doing anthracosis work . The nodular peribronchial sclerosis is remarkable. Osler did describe it in a case of black small-pox in a miner in 1875. Asks his opinion on a question asked by a man working with Haldane, whether a lung ever cleared itself of the dust. Of course, he knows that old miners expectorate coal dust to the end. Asks him to thank McLachlan for his admirable paper. He has been also interested on the one on purpura by Weil and McMeans. Glad of the work they are putting out from Pittsburgh.
