By doubling the windows of the hall of the Institute 

 which it is proposed to heat, it would be possible easily,

 advantage besides that of which we have just spoken. 



Since the hall is surrounded by very high buildings 

 which are close to it, there is a deficiency of light in 

 the hall which is very noticeable, especially in cloudy

As to the means of heating, it is certain, from the

3d. As the boiler can without any inconvenience be

 intended for the boiler, and in regulating its consump-
