3. POPULAR FIELD BOTANY; containing a familiar 

 and technical description of the plants most common to 

 the various localities of the British Isles, adapted to the 

 study of either the Artificial or Natural Systems. By 

 Agnes Catlow, Author of ' Popular Conchology.' 



" This is a useful aid to young persons in the country who are at a loss how to 



take the fii-st steps in Botany. In this, as in so many other piu'suits, the earliest 



stage is that which is most difficult to get over — each succeeding advance becomes 



more easy than its predecessor. One of the impediments in the way of those who 



\ have no teachers, is the uncertainty that in the beginning attends all attempts at 



I making out the names of the objects they have to examine, and this impediment can 



\ only be removed by drawings and very familiar desciiptions. Miss Catlow, in the 



< work before us, has fui-nished a clear and concise supply of both. We recommend 

 / her Popular Botany to favourable notice. " — Gardeners' Chronicle. 



5 " Now when spring is approaching how pleasant would it be to wander in the 



\ fields with this instructive guide." — Literary Gazette. 



\ " The design of this work is to furnish young persons with a Self-instructor in 



\ Botany, enabling them with little difficulty to discover the scientific names of the 



\ common plants they may find in thek country rambles, to which are appended a few 



i facts respecting their uses, habits, &c. The plants are classed in months, the iUustratious 



< are nicely colom-ed, and the book is altogether an elegant, as well as useful, holiday 

 \ present." — Illustrated London News. 



) " The arrangement of the work is entirely novel ; it is divided into twelve parts, 



\ each part containing the botanical lesson for the month." — Liverpool Chronicle.
