The arrangement of minerals adopted in the following Catalogue, though unsystematic according to the views of modern mineralogists, is an old-fashioned one, which will be found far more useful, in familiarizing the student quickly and easily with the general aspects of the mineral kingdom. These he will find himself at liberty, as his knowledge advances, to systematize either at his own pleasure or under the direction of his tutors;—but I would request that the numbers, attached to my specimens, be preserved: because I am at present endeavouring to organize a system of mineralogical instruction for schools, in which the accessible specimens to which it will refer, in provincial towns, may be permanently connected by their numbers, both with each other, and with the great central examples of mineralogical structure, which have just been so admirably arranged under the windows of the north side of the mineral gallery in the British “Natural History Museum” at Kensington.
