Mix as required, to a stiff putty with boiled linseed oil. (This must be warranted free from any trace of adulteration with fish oil, and it is commonly necessary to buy raw oil of a practical painter, who should know that it is pure, and boil it for a few minutes, to drive off the water in the raw oil.) The simplest and best aquarium cement, the formula of which has been given me recently by the United States Fish Commis- sion, is made as follows : Stir together dry, by weight, eight parts putty (dry whiting), one part red lead, and one part litharge. Mix, as wanted for use, with pure raw linseed oil, to consistency of stiff Fig. 161. Section of Corner of Aquarium 1 Although not necessary, I generally put one or two coats of copal, or spar varnish, around the angles on the inside. No aquarium has leaked when this has been done; and if a leak occurs, it is necessary only to drv very thoroughly and varnish on the inside around the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hodge, Clifton Fremont, 1859-.
