The Student's Flora of the British Islands. By J. D.

Hooker, C.11_ (Macmillan.)—" The object of this work is to supply students and field botanists with a fuller account of the plants of the British Islands them the manuals hitherto in uso aim at giving." Dr. Hooker's name will be guarantee for the energy, industry, and complete acquaintance. with the subject with which the object thus stated is pursued. The- book, it should be understood, is meant for students; an amateur might. not improbably be puzzled by the multiplicity and particularity of the detail—imagine more than twenty sub-species of the rubus or bramble— but the student could not have a better text-book.
