accompanies this account, weighed one pound seven ounces 

 and a half ; it measured, in circumference, one foot two in- 

 ches and three quarters ; and in height, as it stood, it was 

 four inches. It proved very good, though it was over ripe ; 

 it was very close at the core ; and if a good bearer, will de-

At the same Meeting, Mr. George Anstice of Stock- 

 land, near Honiton, communicated a plan for heating Hot- 

 houses on an economical principle, two houses being heated 

 by one fire, in the following manner ; a common cast iron 

 stove is inclosed in an outer case, large enough to leave a 

 space of a few inches all round ; one iron pipe proceeds 

 from the back of the stove into the flue of the house which 

 is to be heated, and thus the smoke acts as in a common flue. 

 Another pipe is inserted into the outer case, without hav- 

 ing any communication with the stove in which the fire is ; 

 and this carries off the heated air, which is continually formed 

 between the stove and the case, and, by means of vents at 

 intervals in the pipe, discharges it into a second house : the 

 vents may be opened or stopt at pleasure, and thus the de- 

 gree of heat may be regulated. This plan does not, of course, 

 increase the positive quantity of heat, but applies that to 

 advantage which would otherwise be uselessly spent, in heat- 

 ing whatever might come in contact with the sides of the 

 stove.

 him to the Meeting this day. They seem different from the 

 fruit with the same name, received by the Society from the
