Yorkshire Type Ammonites

Abstract

WITH the issue of the eighth part of Mr. S. S. Buckman's “Yorkshire Type Ammonites” the first volume of this important work is brought to completion. The chief aim of this publication, as pointed out in NATURE for February 17, 1910 (p. 455), is to establish on a sound basis, by photographs of type-specimens and by critical and descriptive notes, the species imperfectly made known in the writings of Young and Bird, John Phillips and Martin Simpson. The method followed is akin to that adopted in the well-known “Palæontologia Universalis”; and in undertaking his arduous task Mr. Buckman has been fortunate in securing the collaboration of Mr. J. W. Tutcher, who possesses much experience and skill in carrying out photographic work of this kind.
