Another question of interest is the inquiry in what degree the

 respecting this subject, but farther and more copious obser- 

 vations are required, to afford satisfactory results. 



The Literary Gazette gives, in a tabular form, the results 

 of a work on this subject, from the pen of Mr. Thackrah, an 

 eminent surgeon of Leeds. — Out-of-door occupations. Butch- 

 ers are subject to few ailments, and these the result of pletho-

 Thackrah thinks their lives shorter than those of other men, 

 who spend much time in the open air. Cattle and horse deal- 

 ers are generally healthy, except when their habits are intem- 

 perate. Fishmongers, though much exposed to the weather, 

 are hardy, temperate, healthy and long-lived ; cartdrivers, if

 bandry, &c., suffer from a deficiency of nourishment. Brick- 

 makers, with full muscular exercise in the open air, though
