HASSALL, ON ADULTERATIONS. 
liquorice,, and other drugs. It makes us indignant to read 
of the vile compounds that are employed to adulterate our 
food, but the iniquity becomes more atrocious still when we 
find that the remedies to which we fly for relief for the pains 
produced by the bad food are themselves all likewise adul- 
terated. 
Dr. HassalFs book is illustrated with upwards of two 
hundred engravings on wood, executed from original draw- 
ings by Mr. Henry Miller, Mr. Tuffen West, and Mr. 
Searson. These engravings are most efficiently executed, 
and comprise a series of very valuable microscopic illus- 
trations. They are quite worthy the attentive study of those 
engaged in microscopic investigations, and as they are all 
devoted to the structure of very familiar objects, they may 
be very successfully used as a means of educating the eye in 
a variety of organic structures. We can recommend this 
volume to all who are engaged in microscopic inquiries, and 
especially to those who wish to turn their microscopy to 
practical advantage.
