The object of the Historical Society of Science is to render materials for the history of the Sciences accessible to the general reader, by the publication of manuscripts, or the reprinting of very rare works connected with their origin and progress in this country and abroad.

The plan adopted for carrying this purpose into effect is by an annual subscription of One Pound from each Member, such Member being entitled to one copy of each of the works published by the Society.

The number of Members is limited to Six Hundred, and, until this limit is attained. Members are admitted on the introduction of one of the Council, or by application to the Secretary.

All Communications relative to the Society to be addressed to the Secretary, J. O. Halliwell, Esq., 35 Alfred Place, Bedford Square, London.

Bankers.—Messrs. Cocks, Biddulph, and Biddulph, 43 Charing Cross.
