 countries which nature has preferved from it ; and that it 

 would be much better to deftroy than to cultivate it. 

 : Citizen Celly, in a memoir on the utility of employing 

 analogy in the natural fciences, and on the application of 

 botany to promote the progrefs of rural ccconomy,' endea- 

 vours to prove, that the properties of bodies being a confe- 

 rence of their organization, the more relations there are 

 between them, the more the ufes for which they can be em-

Citizen Gilbert (hewed the neceffity of fubjedting all the

 der to enable the rural fciences to make that progrefs of 

 which they are fufceptible. He thinks it would be necefTary 

 to form rural eftablifhments deftined to enquire into the beft
