 Physiology, before the Board of Agriculture. 



I am, dear Sir, with affection and respect, yours, 



H. DAVY. 



In April Davy joined Dr. Young in editing the 

 eighth number of the Journal. Count Rumford had 

 edited the three first and Dr. Young the four follow- 

 ing numbers. In the third number Davy had given 

 an account of a new eudiometer, and in the fourth 

 outlines of a view of galvanism. In another number 

 he gave an account of a method of copying paintings 

 upon glass, and of making profiles by the agency of 

 light upon nitrate of silver, invented by T. Wedgwood, 

 Esq. He says, ' Nothing but a method of preventing 

 the unshaded parts of the delineation from being 

 coloured by exposure to the day is wanting to render 

 the process as useful as it is elegant.' 



On February 24, 1803, an account of some experi- 

 ments and observations on the constituent parts of 

 certain astringent vegetables, and on their operation in 

 tanning, was read by Davy at the Royal Society. 



He was proposed as a Fellow of the Royal Society 

 on April 20, and elected on November 17. 



A letter from Coleridge to Mr. Purkis, dated Feb- 

 ruary 17, 1803, from Nether Stowey, thus speaks of 

 Davy at this time :

 recorded in Scripture Joshua's, that stood still ; Hezekiah's, 

 that went backward ; and David's, that went forth and 

 hastened on his course like a bridegroom from his chamber, 

 our friend prove the latter ! It is a melancholy thing
