character of each individual, many circum- 

 ftances will make a difference ; foil and climate 

 efpecially. Thefe have the fame effect on 

 the form of trees, which they have on ani- 

 mal life. We not only fee diftant parts 

 of the earth, but even contiguous countries 

 exhibit varieties in the fame fpecies of 

 animals. The Englifh and Scotch horfe are 

 very different creatures. And as climates and 

 foils are ftill more connected with trees,, 

 than with animals, we may obferve a greater 

 difference produced, within a fmaller difhmce. 

 The oak of one country differs in form from 

 the oak of another.. In one, it carries an 

 erect ftem for many yards from the ground : 

 in another, it's branches begin quickly to 

 divide, and ftraggle. In the former fituation 

 the foliage may be thick, and interwoven , in 

 the latter, it may be thin, and meagre. The 

 obfervations therefore, which we have made 

 on the form of trees, cannot in many minute 

 circumftances be fuppofed to fuit the indi- 

 viduals of every country. They were chiefly 

 made on the trees of New-foreft in Hampfhire; 

 the foil of which, in general, is a hungry gravel, 

 or a cold clay.
