*^ In order to afcertain fully how the oven anfwered, a 

 committee, appointed by the Society for the Encourage- 

 ment of Arts, 6rc. ordered two ovens, of fimilar forms and 

 dinienlions, to be fixed to the (ides of a fire-grate in the 

 model-room of the Society, one of which ovens only difFered 

 from the other by the piece of call iron projefting from its 

 fide into the fire : both ovens were heated by the fame fire, 

 and fixed in mortar and brick-work in a fimilar manner. 



'^ Two loaves, of equal fize and quality, being prepared from 

 the fame dough, one was put into each oven; and after remain- 

 ing therein three quarters of an hour, they were taken out at 

 the fame time, and examined. The loaf from Mr. Holmes's 

 oven was in every refpe6l well baked, but the other was 

 dough-baked and imperfe6l. An oven upon Mr. Holmes's 

 couftru6tion has been fince fitted up in the Regifter's kit- 

 chen, which appears to anfwer every purpofe that could be 

 expelled from its fize, which is 13^- i^^ches wide at the door, 

 or in front, and 15 inches deep. 



^^ A reference 10 Plate I. fig. i and 2, will explain more 

 fully the confl:ru(Stion of the oven, and its principle of a^iion.
