LINNEAN SOCIETY. 
MY DEAR SIRS, 
IF I were not anxious to acknowledge 
you amongft the number of thofe, whofe ufeful infor- 
mation has in various inftances tended to improve this 
Work, motives of efteem would alone induce me to in- 
feribe it to you. The refleétion, that for ten years paft, 
it has been fanGioned with no inconfiderable fhare of 
public approbation, will not allow me to believe it un- 
worthy of your attention, and its conclufion affords 
me the beft opportunity to teftify the favour, as well as 
the refpe@t, with which 
T remain, 
Moft fincerely yours, 
E. DONOVAN,
