AN ELECTRIC HOT FUNNEL THEO. OTTERBACHRR, ZION COLLEGE, ZION, ILLINOIS When an ordinary hot funnel (that is, one heated by a Bunsen burner) is used, considerable inconvenience is experienced because the apparatus is not a unit and also because of the open flame of the burner. The electric hot funnel suggested by the writer has been found, after two years trial, very efficient in operation, and to eliminate certain disadvantages of the older type such as those listed above. The projection (A) of an ordinary hot funnel is covered to the thickness of one-eighth inch with asbestos (B) and over this asbestos is wound enough resistance wire to give the heater a capacity of 400 watts (27' 6" no. 22 nichrome wire). After the wire is in place and suitable connections are made the whole projection is covered with a mixture of asbestos pulp and plaster of Paris (C) to the thickness of three-eighths of an inch. As soon as the plaster is dry the funnel is ready for use. Science Senice reports that the housekeeper may soon be able to buy her lamb or mutton with mint sauce already in it and her chicken already flavored with mace and thyme. The new method of flavoring, devised by Dr. A. Gauducheau, a Frenchman, consists in hypodermically injecting seasonings into the blood stream of the animal.
