Excerpt from The American Journal of Pharmacy, 1872, Vol. 44 The processes detailed in this essay were conducted at the Phila delphia College of Pharmacy, in presence of the large class of stu dents, with such facilities only as a lecture-room, with its counter, sink. Hydrant, and gas-supply afford. The energies of the lecturer being mainly directed to explanation and oral instruction, an assistant is employed in the management of the several processes simultaneously going on during the lecture; to his skilful assistant, Jos. P. Remington, the writer acknowledges himself indebted for useful suggestions, especially in the construction of the steam evaporating apparatus herein described.
