 quence of the diffusion of the practice. 



" Whenever the horticulturist determined it to be a primary 

 consideration in the heating of the hot-house, to preserve with 

 the least fluctuation any given degree of atmospheric tempera- 

 ture, the advantage of employing water in preference to steam, 

 for the attainment of that end, was obvious, and could not fail 

 to present itself to any mind conversant with its use for that 

 purpose. The practicable attainment of it could not be 

 attended with difficulty, as it had long been effected under 

 analogous circumstances.
