PHYSIOLOGICAL AND MEDICAL KEMAIXS. 383 



with a view to obtain better and cheaper manufactures. 

 They were referred to one Dr. Meverel, a chemist of 

 that day, whose answers Tenison has printed along with 

 them. These answers, as they may perhaps throw 

 some light upon the state of chemical science in Ba 

 con's time, I have appended as notes. 



The experiments about weight in air and water have 

 some interest in connexion with Bacon's method of de- 

 termining specific gravities, as explained in iheJEKstoria 

 Densi et Hari ; concerning which Mr. Ellis has con- 

 tributed a valuable note. 



Among the Physiological Remains, Tenison has in- 

 serted a speech touching the recovering of drowned min- 

 eral works, fathered upon Bacon by Edward Bushel, a 

 great projector of such things, who in his early youth 

 had been in Bacon's service. His story is that this 

 speech was prepared by Bacon for the Parliament of 

 1621. But Tenison evidently did not believe it to be 

 genuine ; and it is in fact so manifest a fabrication that 

 I have not admitted it at all into this edition. It is 

 obviously a mere puff of some project of Bushel's own. 



The other pieces sufficiently explain themselves.
