to be fanguiuc about his fuccefs in it His lalxnirs in it however do 

 him great honour; and although WC do not adopt hi* genera and fub- 

 divifions, we admin: his acutcnefs in characterizing (pedes. It is only 

 to be regretted tliat this illufirious writer could not have had before 

 him at one view*, all the fpecics lie had previoufly defcribed of each
