EXTRACTS FROM THE PREF 
“The book is for learners, and not for proficients ; the author regards it in no other light, oil puts it forth — -= higher pretensions. It is for those who, having 
y mastered the rudiments as tau cht in the ‘School Botany,’ desire to advance another and a grea r step, and to add to their i or i knowledge of 
the forms of plant and economy, He believes that it is necessary for all — — who would ak botany as a science, to acquire 
‘that kind of preliminary information Which — elements convey ; and he would even venture to add that, in the absence of such knowledge, 10 one can by 
any ibility make satisfactory p i 
“ Nothing tends so much to perplex a student asa cloud of facts which he cannot condense, and amidst which it is impossible for him to ie h the true 
relation which the one bears to the other, or their respective importance, The purpose of this tc ee has been from the beginning to enable him to — 
T this difficulty, —to look upon a clear well-defined i oe presenting no more shadow than is required o throw what is prominent into relief, and what is distan 
into its due Place in the background, —metaphor a apart, to learn exactly and to generalise correctly.
