Tree, or shrub. Jpril. 



A small tree, of very slow growth. Leaves ovate, hardly an inch 

 long, dark shining green, turning to a vivid tint of vermilion in 

 autumn j concave and paler beneath. Stipulas none. Foot- 

 stalks, as well as the young branches, more or less downy. Fl. 

 pale yellow, or cream-coloured, tufted, variable in the number 

 of their petals. 



Box wood is yellowish, hard, heavy, of a firm close texture, not lia- 

 ble to split. Hence its value for making mathematical instru- 

 ments ; and, above all, for engraving in wood ; an art so exqui- 

 sitely improved of late in this country, as to have almost tb^ 

 merit of a new invention.
