HENSLOWS BOTANICAL CHARTS. 



Modified and adapted for Use in the United States, 

 By ELJZA A. YOUMANS. 



One of the most attractive, interesting, and instructive accessories 

 for the school-room ever published. 



A diagram system of illustration, as an aid in teaching a subject like 

 botany, is o valuable that the publishers have been induced, at the 

 risk of heavy expense, to issue this series of charts for school use. 



In the plan of illustration adopted, the plant is first represented in 

 its natural size and colors ; then a magnified section of its flowers is 

 given, showing the relations of the parts to each other, and also mag- 

 nified views of the different floral organs. The charts contain nearly 

 five hundred figures colored to the life, and which represent twenty-four 

 orders and more than forty species of plants, showing a great variety 

 of forms and structures of leaf, stem, root, flower, fruit, and seed. 



The Charts are not designed to supersede the study of plants, but 

 only to facilitate it. Their office is the same as the illustrations of the 

 book ; but they are more perfect, and bring the pupil a step nearer to 

 the objects themselves. Many plant characters are so minute that they 

 are difficult to find, and much is gained by referring first to the enlarged 

 and colored representations. Besides this special assistance in object- 

 study, they will be of great value in bringing into a narrow compass a 

 complete view of the structures and relations of the leading types of the 

 vegetable kingdom. While individual characters are distinctly shown, 

 they are brought collectively before the eye, so as to be readily com- 

 pared and contrasted with each other. As the natural objects are im- 

 aged with such fullness and truthfulness of detail, they will be found 

 equally valuable to the beginner, the intermediate pupil, and the ad- 

 vanced student equally useful in helping to a knowledge of the rudi- 

 ments, and in guiding to the higher classifications of the science. 



They can be used with any botanical text-books, and during the 

 season of plants they should be upon the walls of every school-room 

 where botany is studied.
