 improvement ; efpecially as the maintenance 

 of thoufands depends on thefe important 

 branches of commerce ; yet thefe may be 

 enlarged, by difcovering new properties in 

 animals, or by the farther cultivation of thofe 

 already difcovered-. The fcience of Zoology 

 is requifite for each of thefe ; and if we refledl 

 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 manufaftures and 

 commerce. 



Domeftic oeconomy is an objed of equal 

 confequence; and the author* of the Ca- 

 lendar of Flora has eflabliflied 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. Stillingfleety in the fame 

 year purfued almoft the fame plan as far as 

 his time would permit, with equal fuccefs,
