Monograph of the British Graptolitidæ

Abstract

IT is with no small degree of satisfaction that we welcome the appearance of the first part of Dr. H. A. Nicholson's Monograph of the British Graptolites, the first English essay attempting a clear digest or history of this very difficult and perplexing group of fossils. Dr. Nicholson has, however, for years lived in those regions whose rock masses, life contents, and structure were long since elucidated and rendered classical and famous by the researches of Sedgwick in 1848; and where these organisms are most abundantly distributed. Patient investigation of the great stores of entombed materials at his command, combined with requisite knowledge of zoology, has favoured the author in the preparation of this valuable contribution to our hitherto limited knowledge of these extinct forms of life.
