ceconomy or propriety. Till farther experiments^ 

 therefore, (ball afcertain this point, we may take it 

 as a fafe rule, that the heat fhould be kept up, if. 

 poiTible, between the 50th and 55th degree; and 

 to afcertain this point, a thermometer, graduated by 

 Fahrenheit's fcale, fhould be hung up perpetually in 

 the milk-houfe, to give notice to the owner of any 

 alterations in the temperature that might afFedl his 

 intereft. Luckily it happens that this is very nearly 

 about the average temperature that a building, fo 

 well fecured as this is from the external air, would 

 naturally bear at all feafons of the year in this cli- 

 mate, were it not to be affedled by external obje6ls. 

 But as the heat of the milk, if it were in confiderable 

 quantities, would tend in fummer to afFed the tem- 

 perature of the air, there is no impoflibility but it 

 might thus be raifed on fome occafions to a higher 

 degree than was proper. It was to have at all times 

 at hand an eafy cure for this diforder that I wiihed 

 to call in the afliftance of the ice-houfe, as a fmall 

 quantity of ice, brought into the milk-houfe at any 

 time, would quickly moderate the heat to a proper 

 degree. In the two fmall chambers adjoining to the 

 ice-houfe too, or in the paffages around the ice- 

 houfe, the butter would be kept even cooler than 

 in the milk-houfe itfelf. Other advantages that 

 would arife from thi§ fmall additional building will 

 appear obvious. . ^
