 ^^M<ho\vli?ge requisite to complete such a desideratum# 

 which de<nands the most exact acquaintance cbemicalty^ 

 boianically, 'and by dissection with every single plant. 

 Drawings embracing most of the appearances are neces- RequUltes for 

 •ary ; with the addition of a simple account of those pecu- '^^•* 

 liarities, which distinguish the class, the order, the genus, 

 and species; pointing out the various marks, that ally a 

 plant to each diftereht family ; mentioning the plants with 

 which it naturally ranks, and /Ao^jr /rmV^ that form it^ 

 artificial relations ; explaining also its £Lrst rise form the 

 seedy with all the peculiarities that attend its infant state. 

 Its juices must next be described; the chemical properties 

 of both b/ood and sap ; the manner in which they flow ; and 

 any variation that may appertain to its interior structure; 

 which is perhaps one of the most curiovs parts of a plant, 

 ■net affoi^s us an antilogy never' before sought. The form- 

 ation of the flowers must be compared with those of the 

 apecies not ouXy ex tern allt^hwlintcrfiaUy; on the latter of 

 which much oi the AaJiV of a plant depends. The species 

 of root must be shown, with its interior formation, and the
