LETTERS OF DR. EMMONS. 
To the Hon. Christopher Morgan, Secretary of State, and 
T. RoMEYN Beck, Secretary to the Board of Regents : 
Sirs — In compliance with your request I submit the following 
statement respecting the condition and progress of that part of the 
Natural History of New- York, which is under my charge : 
1. Of the 50 plates of insects which were assigned to the depart- 
ment of agriculture, 19 have been engraved ; one is in the hands of 
the engraver, and one nearly completed in the hands of the draughts- 
man. These plates average 24 figures, the whole number amount 
453. The 30 plates which remain will have 750 figures, averaging 
25 per plate.
