 North Carolina; Dr. Jerdon, South India ; W. Theobald, Esq., 

 Jnr., Punjab and Pegu ; E. Kobinson, Esq., Assam ; Lieut.-Cols. 

 Phayre and Tytler, and others noted in the proper place.

 for the great care he has bestowed on the Plates, which, it must 

 be allowed, reflect considerable credit on his pupils to whom their 

 execution was entrusted.
