110 BEALE, ON THE MICROSCOPE. 
with which the microscopic observer alone can deal, and we 
shall be glad to find it exciting the attention of our contri- 
butors. 

The Microscope in its application to Clinical Medicine. By 
Lionet Beate, M.B. Second edition. London: John 
Churchill. 
On the appearance of the first edition of this work (vol. i, 
p. 267) we gave it our highest commendation; and the 
fact of its having so soon reached a second edition shows 
that our high estimation of its value was correct. Short, 
however, as has been the time since the publication of the 
first edition, it has been one of great advaneement in the 
direction of microscopical research. Hasty generalizations 
have been corrected, incorrect observations have been ex- 
posed, increased facilities for investigation, by the improve- 
ment of the microscope, have been introduced, new methods 
of research have been employed, and a large addition has 
been made to our knowledge of minute structure, during the 
last four years. For many of these results we are not a little 
indebted to Dr. Beale’s book, and to the unwearied industry 
and singleness of purpose with which Dr. Beale has worked 
with the microscope. When we see how much work Dr. 
Beale has done the last four years, and recollect that during 
that time he has performed the duties of Physician to King’s 
College Hospital, and Professor of Physiology in the College, 
we cannot but marvel at the extent of his labours, and hope 
that he is not taxing his physical powers to an extent which 
he or his friends may have occasion to lament. 
This second edition has been everywhere improved and 
brought up to the time. Many new observations of impor- 
tance, and much matter entirely new are added. Many 
new woodcuts are given. We must also offer our thanks 
to Dr. Beale for another improvement, and that is, a 
copious quotation of authorities. This is done not only in 
the text, but at the end of every chapter there is a list of the 
works to which either the author is indebted for his informa- 
tion, or which the student may consult for a more complete 
knowledge of the subject. 
The whole work has been re-cast, the arrangement is new, 
the type is larger, and the volume bigger than the last. We
