noides, should be planted ; while on the lower and damper 

 parts should be placed such as inundation and clavatum. 



The soil employed should be peat earth intermediate in 

 texture between the spongy and the unctuous kinds ; that 

 used among the rock-work may have in addition a portion 

 of the sandstone pounded and intermixed with it. That used 

 for inundatum in the lower part of the case will not require 

 this intermixture, and, in fact, will be the better as it ap- 

 proaches the unctuous texture just referred to, which the 

 presence of a good supply of water will soon give to it. 



All parts of the soil should be kept rather moist than 

 otherwise, by the application of fresh water occasionally ; 

 but as the confinement of the atmosphere in the damp 

 state, in a close case, might tend to produce decay in some 

 parts of the vegetable tissues, the little door or hinged sash 

 may from time to time be left open for a few hours, in 

 order that the stagnant moisture may be carried off, when 

 a fresh supply will be doubly grateful to the plants. 



It must be recollected, that the soil will be exposed to 

 very slight drying influences, and can, therefore, never re- 

 quire to be very copiously supplied at any one time ; the 

 proper course being, rather to ventilate frequently, say 

 once a week, in order to carry off the accumulated damp-
