Aquaria. — This being a subject a little outside my province, 

 I do not purpose dwelling on it, further than to say that all 

 information will be found in " The Aquarium, its History, 

 Structure, and Management," by Dr. J. E. Taylor, F.L.S., &c.; 

 Gosse's " Handbook of the Marine Aquarium," and many 

 others. Two recipes, culled from the Scientific American, 1879, 

 may be of service, however : " Cheap tanks can be made of wood 

 and glass, the frame and bottom being of wood, and sides of 

 glass. In order to make the joints watertight, care must be 

 taken to get a proper aquarium putty or cement. The follow- 

 ing is a good recipe : Put an egg-cupful of oil and 4oz. tar to 

 lib. resin, melt over a gentle fire, test it to see if it has the 

 proper consistency when cooled ; if it has not, heat longer, or 

 add more resin or tar. Pour the cement into the angles in a 

 heated state, but not boiling hot, as it would crack the glass. 

 The cement will be firm in a few minutes. Then tip the 

 aquarium in a different position, and treat a second angle 

 likewise, and so on. The cement does not poison the 

 water." 



" To mend the broken glass of an aquarium, fasten a strip 

 of glass over the crack, inside the aquarium, using for a cement 

 white shellac dissolved in one-eighth its weight of "Venice 

 turpentine."
