sened; but still colored the urine considerably. This bleeding did 

 not entirely cease till the following April '). 



In Diptheria, I have found the Mycelium of a species of Pe- 

 ronospora, growing in the exudation and in the subjacent epi- 

 thelial tissue. This plant is figured and described in a paper on 

 the cause of Diptheria. 



Case 3. Mr. J. H. — a carriage maker, — aged 28 — of 

 good constitution and regular habits ; but a great vegetable feeder, 

 and especially fond of potatoes; was attacked with Erysipalis of 

 the face, July 18"' 1867. He had been living freely upon old po- 

 tatoes, that were beginning to be affected with the rot. The swel- 

 ling began just above the right eyebrow. Thinking it a boil he 

 opened it. Swelling continued and extended over the forehead, 

 partially closing both eyes; and on the 2P' when 1 first saw him, 

 he was dizzy and delirious, — one eye was shut and the other 

 nearly so, and face and forehead very much swollen. The urine 

 was high colored and scanty, and bowels costive. On examining 

 the blood under the microscope, found the spores and filaments 

 of one of the mucedinous fungi, — which proved to be , by deve- 

 loping in a closely stopped bottle, the Peronospora infestans, 

 (Botrytis infestans), — the plant that produces the rot in the po- 

 tatoe. Ordered 2 grains of quinine every 2 hours and 20 drops of 

 Tinct. Feni — chlorid — in a full tumbler of water every 4 hours, 

 the face and scalp to be painted with dilute Tinct. Iron — 

 morning, noon and night, to have bowels kept open once daily 

 with effervescing draughts of cream tartar and Bicarbo. soda, — 

 and to have all the beef tea he can take. Patient began to im- 

 prove on the following day, and recovered rapidly, so that in ten 

 days he was at his work. 



Case 4. Mr. A. O'D. of New York, was attacked with ery- 

 sipalis at Meadville Pa, — where he had been watching night and 

 day for about two weeks with a friend who died with malignant 

 erysipalis. The swelling began in the wing of the nose and cheek. 

 About 24 hours after the attack, he started for Cleveland. The 



1) O'Brien states that potatoes affected with the rot, produced by the 

 Botrytis infestans, excite (when eaten) heat of skin, accellerated pulse 

 and abdominal pains. Second, rose colored spots, migrating and evanescent 

 and diorrhoea. In the third stage, tumefaction of the muscles and neck, shoul- 

 ders and arms, — acute pain there and in the worst cases, — Erysipalis of 

 the face and scalp and oedema of the eyelids.
