366 Notices respecting new Booh. 



60 much from each other with regard to a variety of ilW- 

 portaiit particulars, as the climate in which theV reside, the 

 manner in which they are formed, &c. that there must rte*- 

 ccssarily be a material difference with respect to the dvlration 

 of their lives. It is essential therefore, in the first place, 

 to ascertain what these particulars are. It seems to me 

 that they may be all comprehended under the following 

 general heads : 



1 . Form and growth of the indivlduaL 



2. Natural constitution. 



3. Disposition of mind. 



4. Parentage. 



5. Climate. 



6. Education. 



7. Rank in life. 



S. Particular occupation. 

 9. Connubial connexion. And 

 10. Sex. 

 Where a favourable condition of all, or the greater part 

 of these circumstances occurs, there health and longevity 

 may be expected. 



In some particular cases also, it may be proper to remark 

 that nature seems to make a fresh effort, and in some mea- 

 sure to renew the distinctions of youtli, and some of the 

 ■ circumstances which attend it.

 Rules for preserving health a ud promoting tongevifij. 



It is evident, that if men hved uniformly in a healthy 

 climate, were possessed of strong and vigorous frames, 

 were descended from hcalthv parents, were educated in a 

 hardy and active manner, were possessed of excellent natu- 

 ral dispositions, were placed in respectable situations in lifo, 

 were engaged only in healthy occupations, were happily 

 connected in marriaaje, &c. &c. there would be little occa- 

 sion for medical rules. But it is universally know^n, that 

 some individuals enjoy only a- part of those advantages, 

 whilst others, possess hardly any of them complete. Hence 

 arises the necessity of attending to those rides which obser- 

 vation and experience have pointed out as being the most 

 likely to counteract the dii^advantages arising from so ma- 

 terial a want as of any of the natural advantages above enu- 

 merated. T'lese rules relate to 



1. Air. 



2. Diet. 



3. Digestion, and its cffccts, 



4. Clothing.
