Vol. 2 September, 1916 No 1 



sank below the surface of the water, it 

 became chilled, circulation stopped, and 

 I saw at once that it would not work. 

 Out it came, and was relegated to the 

 junk heap. 



I went to a friend with my problem, to 

 Rev. Paul W. Roth, and, much as I 

 would like to take it myself, I must give 

 him credit for the "storm window" 

 heater, contenting myself with the credit 

 of constructing it with a slight improve- 

 ment over his idea. It has at least one 

 advantage over other hot water systems 

 in that no metal — pipe or anything else — 

 is placed in the aquarium. The heater 

 consists of what we will term a "storm 

 window," enclosing a hot water radiator, 

 and placed on the outside of the tank 

 and out of sight from the room. The 

 "apparatus consists of a frame or shallow 

 box the size of the tank, and one and 



one-half inches deep, with a light of glass 

 set in it. It in no way obstructs the light, 

 and, if it did no more, it would keep a lot 

 of cold air away from the window side 

 of the aquarium. The frame is placed 

 against that of the tank, and in the re- 

 sulting space of one and one-half inches 

 between the two pieces of glass is placed 

 the hot water radiator, for which any 

 suitable small tubing may be used. I 

 chose small lead pipe having an internal 

 diameter of one-quarter inch, such as is 

 used in the construction of pipe organs. 

 The portion that is outside of the frame 

 is made of copper tubing, a part of which 

 is bent to form the heating coil. Around 

 this coil is placed a heat-retaining cone 

 of tin. After the system has been filled 

 with water a bottle of water is inverted 

 and placed in the brass expansion funnel. 

 By this means the system is supplied con- 

 stantly, evaporation is slight, and con- 

 stant watching of the water level is obvi- 

 ated. The heater is held close to the 

 aquarium by means of clamps made from 

 strips of sheet metal. 



I have intimated that the room in 

 which I keep my fishes is not easily 

 heated in cold weather, but with the 

 heater I have had no difficulty in main- 

 taining a temperature of 72 to 74 degrees 

 Fahrenheit, in the tank with a tempera- 

 ture at times in the room of about 60 

 degrees, and have been unable to detect 

 a variation of the water temperature, 

 showing that the radiation through the 

 tank is very good. The aquarium has a 

 capacity of about twenty-five gallons, 

 measuring thirty by fourteen by fourteen 

 inches. 



Just a word in regard to the source 

 of heat and its application. I have no 

 doubt but that good results could be se- 

 cured by using a small oil lamp, but I 

 find that a Welsbach burner from an up- 

 right light, with the mantle removed but 

 retaining the screen cap, will do all that
