PORTRAIT OF PROFESSOR HARVEY. 



IT was the intention of the Publisher to have prefaced this volume 

 with a portrait of the Author. The Author's absence in the New 

 World prevents this until his return, which is not expected before 

 Midsummer, 1850. As soon after this time as the engraving can 

 be finished, the Publisher will deliver the print, free of charge, in 

 exchange for this notice, which purchasers of the work are solicited 

 to sign and present, either direct, or through their respective Book- 

 sellers.
