LKCT. t.] OP BOTANICAL SCIENCE. 36 



of the Physiology, on which modern Chemistry has 

 thrown the most brilliant light, the tediousness of 

 acquiring the terms of art is diminished, and 

 much interest excited in the pursuit. It is neces- 

 sary to state that Botanical Terminology is that 

 part of the science which has been less improved 

 than any other, since the time of Linnaeus. Some 

 reform, similar to that which chemical nomencla- 

 ture has undergone, is wanting, to remove the 

 rubbish with which it is encumbered ; for, although 

 arbitrary terms are less objectionable in Botany, 

 yet the terms employed should be clearly defined, 

 and comprehensive. I would recommend, on this 

 part of the subject, the perusal of Sir J. E. Smith's 

 Introduction to Physiological and Systematic Bo- 

 tany ; Rousseau's Letters on the Elements of Bo- 

 tany; Mr. Curtis* Lectures; Willdenow's Prin- 

 ciples of Botany^ which have been well translated ; 

 and, to those who read and understand French, 

 the Traite* d'Anatomie et de Physiologic Vgtales, 

 of Mirbel ; but, above all, the Philosophia Bota- 

 nica of Linnaeus, Those who wish to investigate 

 the subject more closely, will find great satisfac- 

 tion in looking into the works of Grew and Mal- 

 pighi; DuHamel, Hedwig, De Saussure, Gsertner, 

 and Spailanzani; and Mr. Keith's System of Physi- 

 ological Botany. But I will forbear, at present, 

 from loading your memories with the names of 

 authors,, and rather notice them as we proceed,
