JACKSON, B. DA YD ON, 



A GLOSSARY OF BOTANIC TERMS. By 

 B. Daydon Jackson, Secretary of the Linnean Society. 

 Crow7i Zvo. ^s. net. [In the press. 



This volume is intended to supplement existing text-books, by ofTering in one work a 

 comi)reIiensive vocabulary of the terms in use from the time of Nehemiah Grew to the 

 present day. The copious additions to botanic language made during the last twenty 

 years have not hitherto been published in a complete form in this country. The author has 

 endeavoured to supply this deficiency, aided by the encouragement and help of many of the 

 most distinguished botanists in many branches of the science. 



PERCIVAL, JOHN 



AGRICULTURAL BOTANY, THEORETICAL 

 AND PRACTICAL. By John Percival, M.A., 

 F.L.S., Professor of Botany at the South-Eastern 

 Agricultural College, Wye. Crown Svo. 6s. ;/<?/. 



[/;/ tJic press. 



Practical men and the Agricultural press have from time to time complained that no 

 text-book of Hotan)' exists which is suitable to the wants of the student of Agriculture 

 — those in existence being works which treat the subject from a purely scie/itific standpoint, 

 and contain a large amount of matter which is without use or practical application. 



The rapid advance of technical education, the applioition of science to industries, and 

 the growth of colleges and centres for agricultural and horticultural teaching, have made 

 it imperative that the above defect should be remedied, and the present volume therefore 

 deals with those facts of the science of Botany only which are essential to the requirements 

 of students at such colleges and schools, and is also suited to the needs of the rising 

 generation of practical farmers. 



The contents are based on several years' experience in teaching and lecturing to students, 

 practical farmers, and gardeners, and will embrace chapters dealing with the structure and 

 physiology of plants in general ; the elements of classification with more complete treat- 

 ment of the IJotany of farm plants, cereals, root and forage crops, temporary lays and 

 permanent pasture, with the grasses concerned in the latter; seeds of the farm, their 

 peculiarities in regard to purity and quality of commercial samples, diseases of farm crops 

 caused by attacks of parasitic fungi, and other matters of similar importance. 



Most of the illustrations have been specially drawn for this work by the author himself 

 from living specimens, or photographed from the same. 



In recognition of the great importance of practical work in teaching, every endeavour has 

 been made to introduce illustrative experiments, to be repeated by the students in the 

 field and laboratory; and this idea of introducing experiments to illustrate the various 

 principles taught is carried out as far as possible all through the wdrk.
