 tion, it was deemed advisable, by way of experiment, to try 

 both his method and that recommended by Mr. Gowen, and 

 three entire lights were therefore glazed on each plan, for 

 the house. The experience of the two last winters (the house 

 having been completed in November, 3818) has furnished 

 some observations, which, as they apply not only to the 

 comparison of these two plans, but generally to the whole
