 Millbrook ; and of another Revolving Forcing-Frame by Mr.

of wood or metal, the cover of glass like a cucumber frame, and 

 the whole balanced on, and revolving by means of, iron balls 

 placed in a circular groove (a). The elevation (b) and section 

 (c) of such a frame may be easily conceived. (Mr. Gauen's 

 letter of September 19.) 



Mr. Bisset, referring to the notice of Mr. Gauen's inven- 

 tion in p. 102., says : " I have been engaged for some time past 

 in constructing a revolving forcing-frame, purely of my own 

 invention, the model of which I had prepared so early as the 

 beginning of July last, and a description of which I shall likely 

 send as soon as I can have the experience of its operation." 

 (Mr. Bisset 's letter of October 2.)
