Examination of heat and cold sensibility is often neglected during a routine neurologic examination because the tubes used for this test are bulky and unhandy. The tubes on the market for this purpose are also expensive.

By accident, it was discovered that the tube illustrated here,1 which has been placed on the market as a sterile container for hypodermic syringe and needle, will serve the purpose well. It is inexpensive (costing 50 cents) and handy, and can be chilled or heated to the desired temperature. It is 15.5 cm. long and 4.5 cm. in circumference at the open end and tapers to a point. As it is plated and smooth, it does not radiate. This tube can be carried in a small container, and the rubber cap affords a firm grip at any temperature.
