The management of the Grand Opera House announces the engagement for three nights only. Nov. 11, 12 and 13, of Santanelle, the master of hypnotism, and the most talked about man of the day. His long successful series of entertainments in Detroit, covering 28 performances, caused the liveliest commotion rmoung men of learning, the newpapers particularly, and medical profession generally. Santanelli’s endorsement signed by 75 of 26 medical students from the Detroit College of Medicine and the Michigan College, pronounce him a man of honesty of purpose and thoroughness in all his claims. He is a mystifier of the deepest skill; many physicians and scientific men and women attend his interesting exhibitions, soley for what they may be able to gain in the study of hypnotism.
Transcribed as printed. Perhaps the typesetter should have had some hypnotic training?
I am unable to find any mention of a “Grand Opera House” in Ann Arbor. Perhaps this was a stock ad, and Santanelli performed at Hill’s Opera House?
While I can’t seem to find out anything directly about Santanelli, there are a few surprising references to him at Google Books.
