EXALT AT A (var. Bostonibnsis). 



perature is of less importance as long 

 as this is above the freezing point. The 

 success of un aquarium depends upon 

 the proper action of the aquatic plants, 

 and these require, in order to act prop- 

 erly, their share of light and warmth 

 to the same degree as ordinary house- 

 plants do in order to flourish, and if 

 one can supply these wants, the expense 

 of keeping an aquarium in excellent 

 order is very little indeed. 



To secure success, an aquarium 



should therefore be always near a win- 

 dow. 



In the accompanying sketches we 

 show the various positions that may be 

 chosen for an aquarium. In each case 

 it will be seen that justice is done to 

 the plants in the aquarium as well as 

 to the persons wishing to enjoy an hour 

 or two of wholesome recreation.
