The Microscope. 71 



In the closing chapters there is a special consideration of 

 the various faculties of the mind, which are most critically in- 

 terpreted and analyzed. One finds himself amazed, as he reads 

 page after page, at the wealth of information and amount of 

 labor found between its covers. It will be perused with rare 

 interest. 



Morel's Manual of Histology : 



Queckett's Lectures on Histology. Two Volumes. 



The above volumes have been added to our private library 

 by the gift of Professor Ford, of this city. For over thirty years 

 Prof. Ford has been engaged in teaching Anatomy in the Med- 

 ical Department of this University. During a large portion of 

 that time he has also taught Physiology, and was one of the 

 first in this country to embody in his lectures the minute 

 structures of the tissues. Before becoming connected with the 

 University he imported a microscope at the early date when 

 such an instrument was a constant wonder and surprise. The 

 first great task he had to overcome was to put the instrument 

 together. None of his associates or acquaintances could offer 

 any aid, and thus what he accomplished was truly a result of 

 his own personal effort. The " Histological Laboratory " is a 

 direct outgrowth of efforts made by him early and late ; and it 

 is one of the ambitions of the director of that laboratory to-day 

 to make it after the ideal of its founder and earnest friend.
