P.S8.—The writer of this Essay wishes to return his best thanks to 
those few gentlemen who so kindly and promptly responded to his 
appeal to them. He would most particularly thank His Honor the 
Superintendent of Auckland (Robert Graham, Esq.,) and the Chief 
Provincial Surveyor of that Province, (C. Heaphy, Esq.); also the 
gentlemen composing the Chamber of Commerce at Wellington. To 
Mr. Heaphy he is largely indebted for much useful information in 
Colonial CAconomic Botany, as well as for that portion of the First 
Table containing the Weight and Specific Gravity of Woods, and the 
whole of the last Table herein given.
