"There were three operations at this institution on Thursday, Jan. 28th, and the vapour of ether was administered in each case by Dr. Snow, with very satisfactory results, by means of the inhaler described and depicted in our last number" [a PDF of this article is posted in Snow's Works/Chronological/Presentations]. . . .

"Dr. Snow stated that the temperature of the water in which the inhaler was placed was 65° in the first operation, 70° in the second, and 75° in the third; and that, consequently, the proportin of vapour in the air inspired was 44, 50, and 55 per cent. respectively" (158).
