Professors of tlie Yorkshire College, and lie published a popular 

 little work upon the ' Birth and Growth of Worlds.' But the book 

 by which Green was most widely known among geologists and lovers 

 of geology was his ' Manual of Physical Geology for Students and 

 General Readers,' the first edition of which was published in 1876, 

 and which attained to a third edition in 1883. This manual is 

 admittedly the best English work in this branch of the science. It 

 is remarkably typical of its author, thoroughly practical and almost 

 painfully conscientious ; it is lucid and modest, but at the same time 

 original and bold ; and it has done more, perhaps, than any other 

 work to foster a wide appreciation of physical geology. In this 

 work we see Green at his best. His deep love for his science and its 

 students is evident in every chapter. His delight in the beauties of 

 literature and in good literary style gives a peculiar charm to the 

 book as a whole; and the mathematical bent of his mind is evident 

 in the crystallographic part of the work and in his original methods 

 of representing outcrops of strata and the like, methods which have 

 subsequently proved of especial utility in the advance of geological 

 science. 



Professor Green's geological teaching in his lectures, though 

 not perhaps calculated to move to enthusiasm, was exact and 

 thorough. His lectures were usually illustrated by careful experi- 

 ments, and were directed less to the presentation of geological facts 

 and accepted theories than to the inculcation of the true scientific 

 method of research and habit of reasoning. But as an original 

 worker in and as a teacher of practical field geology Green had few 

 equals. His own life training, his special artistic abilities, and his 

 love of detail all conspired to this end ; and there can be no question 

 that it is to his labours and teaching that British stratigraphical 

 geology owes much of its present influence. 



In the death of Professor Green not only has Oxford University 

 lost a most distinguished member of its professorate, but geology 

 has lost a steady and fruitful worker, one who loved the science 

 entirely for its own sake, and whose life was spent in quietly labour- 

 ing for its advancement. His wide knowledge of literature and of 

 general science, and his deep and unbiassed appreciation of all modes 

 of their progress, made him a most pleasant companion; while. his 

 calm judgment and his cautious habit of mind rendered him an 

 invaluable colleague. Always frank and fearless in the expression 

 of an opinion at which he himself had arrived, he was, nevertheless, 

 so hearty, so genial, and so unselfish that his loss will be most 

 keenly felt, not only by all his fellow workers in the science, but by 

 a still wider circle of loving friends.
