By Elizabeth C. ^gassiz and Alexander Agassiz. Fully

This beautiful volume is an admirable companion for the 
seaside resident or tourist, especially for all who are capa¬ 
ble of pleasure from looking at or studying the life of the 
sea. Professor Alexandei Agassiz gives the result of his 
own extended observations and profound researches, relat¬ 
ing to the structure, habits, growth, development from the 
embryo, and other characteristics of New England polypes, 
jelly-fishes or medusae, and star-fislies, illustrating his de¬ 
scriptions with numerous artistic figures ; and Mrs. Agassiz 
adds to the volume the charm of her graceful pen. “ Sea¬ 
side Studies in Natural History” is a work for the learned 
as well as unlearned, fitted to give all delight and instruc¬ 
tion.— Professor James D. Dana, ill American Journal of 
Science.

Never before has science been so completely popular¬ 
ized.— Philadelphia Press. 
Skilfully planned, and tersely written; and, while em¬ 
bodying many general hints as to the method by which 
scientific truth has been reached, it sketches the history of 
science in past times. The knowledge which it imparts so 
gracefully is of the most interesting character, and is en¬ 
forced. by apposite and practical illustration. A more 
delightful scientific work we have never chanced to encoun¬ 
ter; and we therefore cordially commend it to all classes 
of readers.— New York Albion.
