by the condensation on the glass plates, and the trickling down of the 
miniature rain. In the morning, the glass plate which is nearest to and

most heat, exhibits both the condensation and running down of the 
water in a remarkable degree; while the inner plate, receiving heat from 
the air of the room, or by radiation from the objects near it, remains 
quite clear. I have planted a few bulbs in another receptacle (and in 
the same way as to soil and moss), by keeping which in the same room, 
but exposed to the air in the usual way, some judgment may be formed 
of the relative advantages of these different modes of raising such plants.

In the sketches (figs. 69 to 72), I have not represented the outlets for 
superfluous water, which are much in the same way as Mr. Ellis’s above- 
referred to. Neither have I shown the contrivance for maintaining the 
identity of air first inclosed in the case ; it would have confused the 
drawing, and will be easily understood from the description. The size of 
the plates of the sides and tops of figs. 71 and 72 is three feet seven and 
a half inches, by twenty-two and a quarter inches. A piece of tinned 
brass tube, a quarter of an inch in diameter and a foot long, is passed 
through the bottom of the soil-trough at one corner, and soldered to the
