The London edition of this popular and excellent manual, from 
by H. Be 
which this American reprint is taken, was edited nce 
Jones and Henry blow in 1868, who have re-written almost Shame 
the organic chemistry and the chapter on chemical philosophy, 
besides” making <onaiabis additions to all other parts of the 
work, and explaining the atomic weights and notation almost uni- 
now among the chemists. Enough of the old structure 
remains however to give to the work a familiar oe to its early 
friends, with many of whom it deseryedly holds a high place 
among elementary books on chemistry. Its ¢ sompaative fullness 
of detail and general simplicity of style ‘render it convenient an 
attractive as a book of reference for both teachers and students, 
especially medical students; while for the purposes of a drill 
ook in class room instruction, its very fullness is a bar to its use- 
cl an 
equally so to the student who aie faithfully to review the 
teachings of the chemical lecture-room.
