her In a few months, — a blow from which he severely suffered, 

 but sought consolation in the duties of his ministry, and the 

 study of the works of the Almighty. His intense application 

 to microscopical observations had impaired his sight in 1790; 

 and, from that time till his death in 1795, he suffered from 

 severe headach and irritable ophthalmia, which rendered him 

 almost totally blind for the last two years of his life. On his 

 death his papers and MSS. fell chiefly into the hands of the late 

 Mr George Paton of Edinburgh, on whose death they were dis- 

 persed. 



2. Wood's new work on the Mammalia, — The first month- 

 ly part of a new work on Natural History^ by Henry Woods, 

 F. Z. S., A. L. S., which has been nearly seven years in prepa- 

 ration, is announced to appear on the 31st of March. It will 

 combine scientific arrangement with copious detail, and form a 

 complete concentration of all that is at present known of the en- 

 tire class Mammalia, embracing the latest discoveries, and in- 

 cluding an accurate account of the physiology, habits, locality, 

 &c. of every recognised existing species, including the fossils. 

 The illustrations, which are chiefly portraits of the animals

3. On Migrator^/ Habits of certain species of Hirundo and 

 Sylvia, — At a meeting of the Linnean Society, there was read 

 a letter addressed to the Secretary from Charles Lucien Buo- 

 naparte, Prince of Musignano, dated on board the Delaware, 

 near Gibraltar, March 20. 1828, containing some curious facts 

 relative to the migratory habits of certain species of Hirundo 

 and Sylvia. The following are extracts : — In closing my letter 

 I happen to think that the following fact may be thought inte- 

 resting to some of your ornithological gentlemen, A few days 

 ago, being 200 miles from the coasts of Portugal, 400 from 

 those of Africa, &c., we were agreeably surprised by the .ap- 

 pearance of a few swallows (Hirmido urhica and rnstica).
