Twenly-three persons present.

" Studies on the Habits of Spiders, particularly those of the

In compliance Avith the recommendation of the Committee on 

 the Hayden Memorial Geological Award, the medal was conferred 

 on Sir A^rchibald Geikie, D.Sc, LL.D., late Director- General 

 of the Geological Survey of Great Britain and Ireland. 



Archibald Geikie was born in Edinburgh, the 28th of Decem- 

 ber, 1835, the youngest son of James Stuart Geikie. He was 

 educated in the schools of his native city and, after graduation 

 from the UniverRity of Edinburgh, he entered the Geological Sur- 

 vey of Scotland at'the age of twenty years. Three years later, in 

 1858, he published his first book, entitled The Story of a Boulder ; 

 or Gleanings from the Note-Book of a Field Geologist. The 

 work of the Geological Survey was largely confined to mapping, 

 the first general geological map of Scotland being published in 1862. 



While this map was issued under the direction of Sir Roderick 

 I. Murchison, a large part of the work was contributed by Geikie. 

 In 1867, at the age of thirty-two, Geikie was appointed Director 

 of the Geological Survey of Scotland. All succeeding maps of 

 the survey of Scotland were issued under his supervision, many of 

 them being prepared by himself. Somewhat before this period he 

 had begun to publish papers on physiographic geology, his work on 

 The Scenery of Scotland, Viewed in Connection with Its Physical 

 Geology, appearing in 1865. Subsequent papers deal with the 

 effects of glaciation, modern denudation and other physiographic 

 processes. In 1871 he was elected Murchison Professor of Geology 

 and Mineralogy in the University of Edinburgh, The methods of 

 geological surveying were carefully cuitivattKl by Geikie, the results 

 of his experience being given to the world in his Outlines of Field 

 Geology (187(i), which has gone through five editions, the last 

 appearing in 1900. 



In the vear 1882, after serving on the Geological Survey of
