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 Fvices, 
Musci, Alge, and Fungi. 
THE MINERAL KINGDOM 
is divided inte three classes, viz: I. Petra; II. Miner#; III. Fossi1a; 
and numerous subdivisions. But, as the mineral kingdom had attract- 
ed but little of the attention of Linneus, and the progress of chemistry
