Even in aquarian nature-study the war has taught us to rely upon our own re- sources, and this in my case has proven an advantage. I have in my collection a number of species of the smaller fishes which I keep in separate tanks, each heated individually. Until last year I have used the "Thermocon," a blown- glass tank with a glass bulb in the centre of the bottom, which answers very well. Requiring additional tanks, and the one mentioned being no longer obtainable, I decided to make some on the same prin- ciple. As others may feel disposed to follow my example, in addition to a de- scription, I present a drawing giving construction details and a photograph showing how inconspicuous the "heating glass" appears when the tank is equipped. My tanks measure 15 by 10, by 10 inches, and are constructed of galvanized sheet iron. This is a handy size, and best suited to my needs, but can be varied as desired. The "heating glass" is an ordinary drinking glass, measuring two and three- fourths inches in diameter and three and one-half high. Now for the frame, bottom first. Cut a piece of the sheet metal 17 by 12 inches, draw lines an inch from the edge on all sides, snip the square inch from each
