THE AMERICAN 
Journal of Microscopy. 
Now (1881) in its Sixth Year. 
While popular in the general tone of its articles, this journal has always been 
thoroughly reliable, practical and dignified. It addresses itself to the Naturalist, the 
Teacher, the Student, the Physician, and the general reader, and describes all new 
improvements in the construction and methods of using the Microscope, and gives an 
account of the discoveries made by it. 
Illustrations.—No expense 1s spared in illustrating such subjects as demand it. 
The woodcuts which appear in our columns are by the very best artists, and our full- 
page plates have not been excelled by any work produced in this country. 
(== This Journal is not the organ of any Society, butit gives the Proceedings of all 
the Micruscopical Societies of importance.
