MEMOIR OP THE AUTHOR. x lx 



living authority in Organic Chemistry." The 

 translation of the First Part of Dr. Liebig's Re- 

 port on Organic Chemistry,* which has passed 

 to a third edition in this country, and of which 

 the present work is a continuation, has made 

 the name of the author familiar to us ; and the 

 appearance of a new work from the laboratory 

 of Giessen will be no less welcome on this side 

 the Atlantic, than it was on the continent of 

 Europe. 



CAMBRIDGE, June, 1842.
