Australia in January 1888, having been appointed Government 

 Geologist for West Australia. It was here that his most im- 

 portant work was done, especially in the exploration of the rich 

 goldfields of the Colony. In addition to numerous official reports 

 and a geological sketch-map, issued in 1894, he published in the 

 same year a ' Mining Handbook to the Colony of Westerja Aus- 

 tralia,' which proved of great service. His investigations also led 

 to the discovery of artesian water in the country west of the 

 Darling Eange. In 1895 he quitted the Government service; but, 

 after practising for some years as a consulting geologist in Perth 

 and Coolgardie, he rejoined the Survey in 190G as Assistant 

 Government Geologist. He died at Perth in his fifty-ninth year, 

 on February 7th, 1917, leaving a widow and three sons. 



Although the name of the New Zealand geologist Alexander 

 M'Kay is unknown to many, it is highly honoured by those who 

 can estimate the importance of his original contributions to science. 

 Beginning as a fossil-collector, he subsequently became attached 

 to the Geological Survey of the Colony under Sir James Hector, 

 and spent twenty years in the field. A self-taught man. and 

 owing little to books, he was led to study the structural 

 geology of the country, and to form for himself opinions far in 

 advance of the times. His views concerning the part played by 

 block-faulting in the evolution of the mountain-system of New 

 Zealand received scant regard, and have only been brought into 

 prominence by others in later years. Had M'Kay possessed the 

 power of presenting his conclusions more clearly and enforcing 

 them more cogently, his merits as an original thinker would have 

 been generally recognized. 



Upfiet.d Green was one whose services to science are not to 

 be adequately measured by the volume of his published work. 

 Although he had been a keen geologist throughout a long and 

 varied career, and had made many observations both at home 

 and abroad, it was not until his 70th year that he began to 

 make public his results. Cornwall was his chosen field, and his 

 paper 'On the Geological Structure of Western Cornwall," pro- 

 duced in 1909, brought his work into notice, and earned for the 

 author the Bolitho Gold Medal. Other papers on the same area 

 followed, including two written in collaboration with Mr. Davies 

 Sherborn ; and, although brief and appearing sketchy, they doubt-
