THREE KINGDOMS. 



" Wild Birds Portfolio." A selection of 40 beautifully colored 

 plates put up in two handsome boxes, 20 plates in each box. 

 Price per box, $1.50. 



Their list includes "Garden Flower Portfolios," 4 boxes, 20 

 plates in each box, at $1.50 each; "Wild Flower Portfolios," 

 6 boxes, 20 plates in each box, at $1.50 each ; " Flower Garden

In selecting books for reference and study, members of the 

 Agassiz Association cannot do better than consult the classified 

 and descriptive catalogue of D. Appleton & Co. (New York). 



Besides the works of such masters in scientific investigation as 

 Darwin, Figuier, Huxley, Herbert Spencer, Tyndall, Proctor, 

 and others, they publish a number of important books in almost 

 every branch of scientific study. Their "Scientific Primers" 

 are noteworthy attempts to convey information in such a manner 

 as to make it both intelligible and interesting to beginners. 



A series of elementary works on mechanical and physical 

 science are published under the general heading of " Text-books 

 of Science." These books are practical treatises, sound and 

 exact in their logic, and illustrated by well-selected examples 

 from familiar processes and facts. 



Mention should also be made of their well-known ' Inter- 

 national Scientific Series," which consists of sixty or more large 

 volumes, covering a wide range of scientific research, and form- 

 ing quite a respectable library in itself. 



In glancing through the catalogue, we find many titles which 

 are sure to excite an interest in the minds of the younger members 

 of the Association. 



The " Fairy Land of Science," for instance, or " Life and Her 

 Children," and "Winners in Life's Race," by Arabella B. Buckley, 

 are sure of an interested audience in whosoever's hands they may 

 fall. Then we have "A World of Wonders; or, Man-els in 

 Animate and Inanimate Nature," wherein many curious tales are 

 told of marine and vegetable life and the insect and reptile world ; 

 " Light Science for Leisure Hours," a series of familiar essays on 

 scientific subjects, natural phenomena, etc.; Dr. Abbott's 'A 

 Naturalist's Rambles About Home," which tells of country walks 

 and studies of the habits of the wild creatures of our woods and 

 fields; Sir John Lubbock's "Ants, Bees and Wasps," contain- 

 ing the record of various experiments made with ants, bees and 

 wasps during a period of ten years, with a view of testing their 

 mental condition and powers of sense ; P. H. Gosse's " Evenings 

 at the Microscope;" Grant Allen's "Flowers and their Pedi- 

 grees ; " and many others equally interesting.
