to Mr Alister Thomson for piloting me safely over many deep waters in the course of my studies. To Mrs E. A. Hodgson, who so willingly and generously undertook the determination of some 300 or more specimens of the hepatics, I owe a special debt of gratitude. Mr G. O. K. Sainsbury again assisted me with the moss determinations, and I cannot speak too highly of the value of his ever-ready assistance.
