Mr. M. Buys-man, of Middleburg, Holland, has started a very useful enterprise in preparing sets of dried plants to suit various objects. The farmer may, if he chooses, buy an herbarium of weeds; the druggist, an herbarium of plants used in pharmacy; colleges, plants suited to their various teachings; and the general botanist, anything he wants. Plants for physiological teaching, with the parts desired properly dissected and dried, are also among the articles offered.

Any one interested can correspond with Mr. Buysman at the address given.
