the Natural Families which have been pointed out, an 
account of the uses to which the plants in each family : 
may be applied, and an explanation of Dz CaNpoLue’s, _

The ultimate object of all botanical knowledge is an 
acquaintance with the uses of plants; under each na-

properties of the leading plants which it contains, un-
