Royal Academy of Sciences of Paris. 139 



While we request you to accept our congratulations, we deeply 

 Jament the occasion of our illustrious townsman's resignation. 



Be pleased, Sir, to take an early opportunity of conveying to Sir 

 Humpnry Davy our condolence on his illness, and our sincere wishes 

 for his restoration to perfect health, and to the exercise of those 

 faculties which he has employed to the noblest purposes — the en- 

 largement of the boundaries of human knowledge, and the gaining 

 for his name the most enviable kind of immortality (such is his own 

 estimate) "that which is connected with the gratitude and blessing 

 of his fellow-creatures." 



May the enjoyment of health enable you, Sir, to continue for 

 many years in the discharge of the high situation in which you 

 have been so honourably placed, with happiness to yourself, with 

 satisfaction to your associates, and with benefit to the world. 



(By order of the Royal Geological Society of Cornwall,)

 moir by M. Isidore Boullay. — M. Bonastre had presented a me- 

 moir On the compounds of the oil of cloves and of pimento with 

 the alkalies, and several salifiable bases. The principal fact con- 

 tained in this memoir is, that these oils, which do not redden litmus, 

 combine nevertheless with salifiable bases ; but M. Chevreul, re- 

 porter of the Academy, stated, that this fact not being accompanied 

 with the necessary details and precision, is devoid of the interest 

 which it may hereafter possess. M. Bonastre was recommended to 

 continue his researches.
