This apparatus consists of a galvanized iron or tin box (size 7 by 8 by 9 inches), the walls, floor and cover of which are made of two layers, between which is placed a sheet of asbestos to minimize heat radiation. For the front, two layers of glass instead of metal are used.
In this box are placed a two-quart dish (A), a funnel (B), a strip of gauze (C) and an incandescent bulb (D).
A. The two-quart dish is for the saline solution. The peculiar shape seen in the illustration is used to economize space. It is made as broad and as shallow as possible to insure a uniform drop.
B. The funnel receives the saline solution drop by drop and is connected with a tube (E) which leads to the patient's rectum. The tube leading to the rectum is enclosed in one (F) of
