 that correct accounts of them would have been very 

 acceptable to men of science, and to all those who 

 take pleasure in promoting new and useful mechan- 

 ical improvements. 



I should, in particular, have been very glad to have 

 given plans and descriptions of all the various parts of 

 the steam-apparatus that has been put up for the pur- 

 pose of warming the great lecture-room. The boilers 

 for generating the steam are, if I am not much mis- 

 taken, well worthy of the attention of those who make 

 use of steam-engines ; and as the subject is of infinite 

 importance in this great manufacturing country, where 

 the numerous advantages which result from the use of 

 machinery are known and every day more and more 

 felt by individuals and by the public, I cannot resist the 

 strong inclination which I feel, to attempt in a few 

 words to give a general idea of this contrivance. 

 Those who wish to know more of the matter may get 

 all the information respecting it which they can want 

 by applying at the house of the Royal Institution. 



A short Account of the BOILERS lately put up at the 

 House of the Royal Institution for GENERATING 

 STEAM for warming the Great Lecture-Room. 



Over an oblong closed fire-place, furnished with 

 double doors, ash-pit register door, etc., are placed 

 two cylinders of copper, laid down horizontally by the 

 side of each other over the fire, each cylinder being 

 15 inches in diameter and 48 inches long. Imme- 

 diately over these two cylinders, and resting on them, 

 are placed two other cylinders of copper of the same 

 length and diameter ; and over these last, and resting
