Familiar Lessons on Miner alogy and Geology, explaining the 
easiest Methods of discriminating Minerals and the earthy Sub- 
stances commonly called Rocks, which compose the Primitive, 
Secondary, Fleetz or Flat and Alluvial Formations. To which 
is added a Description of the Lapidaries’ Apparatus, &c. With 
Engravings and coloured Plate, &c. By J. Mawes, Author of 
the New Descriptive Catalogue of Minerals. 
The author describes ‘‘ the object of these familiar lessons to 
be, to unlock as it were a casket of useful knowledge, and to 
present to the learner, a compendious view of the beauty and 
value of its contents.” It is written with simplicity, and, as a 
guide to more comprehensive publications, cannot fail, we think, 
to be instrumental in promoting the interests of science. } 
Mr. Curtis has just published a second and enlarged edition 
of his work on the Anatomy, Physiology and Diseases of the Ear. 
In this edition the phy siology i is much ‘extended, and the uses of 
the different parts of the human ear are more fully explained by 
_a minute comparison of its structure with that of the different 
classes of animals, particularly quadrupeds, fowls, insects, the 
_amphibious tribe, and also fishes, The treatment employed in 
the various diseases of the ear is also considerably enlarged.
