THE VEGETABLE KINGDOM 

 is divided into twenty-four classes, according to the number and posi- 

 tion of the stamens ; the greater part of the orders, from the number 

 •of pistils in the flower ; others, by the situation of the seeds, and 

 form of the seed-vessels ; in compound flowers, from the arrangement 

 of the florets ; and the great class of cryptogamic plants, or plants 

 without conspicuous flowers, form four orders, divided into Filices, 

 Mtisci, AlgcB, and Fungi. 



THE MINERAL KINGDOM 

 Is divided into three classes, viz: I. Petrte; II. Miners; III. Fossilia; 

 and numerous subdivisions. But, as the mineral kingdom had attract- 

 ed but little -of the attention of Linnaeus, and the progress of chemistry
