animals, or by the farther cultivation of thofe 
already difcovered. The {cience of Zoology 
is requifite for each of thefe; and if we ree 
but a little on the unwearied diligence of 
our rivals the French, we fhould attend to 
every fifter fcience that may any ways pre- 
ferve our fuperiority in manufactures and 
commerce. 
Domeftic ceconomy is an object of equal 
confequence; and the author* of the Ca- 
lendar of Flora has eftablifhed the ufes of 
Zoology in this particular, with undeniable 
evidence. This excellent writer has united a 
happy invention, with the moft folid judg- 
ment, and certainly merits the higheft com- 
mendations, as a friend of human kind. 
Our ingenious countryman, and worthy 
friend, the late Mr. Sz/ingfieet, in the fame

his time would permit, with equal fuccefs,
