200 OF THE USE, &c. 
We find in the journals of travellers, many 
things mentioned, partly curious, partly ufe- 
full concerning animals, plants, and ftones *, 
but thofe obfervations can be of no ufe to us, 
till we are able to refer each to its genus ; 
that we may make them a part of the fyftem, 
and know that this curiofity, or ufe belongs to 
this, or that objeft, when it happens to come 
in our way. 
§• 15- 
If man was created to give praife to his Cre- 
ator ; if the Creator has made himfelf known 
to man by creation, and revelation ; if all cre- 
ated things are formed with wonderfull me- 
chanifm ; laftiy, if all things were created 
for the ufe of man, and nothing but natural 
things, and the elements can be of ufe to 
him ^ then it may be inquired with the fame 
reafon, to what end any other thing was cre- 
ated, as well as man ; the fupreme Being 
having created nothing but for a certain end, 
and for fome valuable purpofe. We are often 
» ignorant what that purpofe is, but it would 
therefore be impious to fay, that any thing was 
created in vain, fince he declared that every thing 
which he had created was good. Gen. i. 31.
