In presenting the AVollaston Medal to Dr. Alfeed Haee:ee, 

 F.R.S., the PsEsiDEyT adcbessed him as follows: — 



Dr. Haekee, — 



From the first you have recognized, as tou were among the first 

 to realize, the necessity of combinins: field-work with laboratory 

 research. ^Yell qualified by jouv mathematical training to apply 

 the laws of crystal optics and physical chemistry to petrological 

 problems, your early work on the Bala volcanic series, the Shap 

 granite, and Carrock Fell, established your position as a petrologist 

 and field-geologist. Selected to the Geological Survey for the 

 purpose of surveying portions of the Tertiary volcanic region of 

 the West of Scotland, your ten years' service produced two important 

 m.emoirs, on the Tertiary igneous rocks of Skye and on the Small 

 Isles of Inverness-shire, In addition to these, and many other 

 records of observations, your work has always been characterized 

 by a breadth of view and a recognition of fundamental principles. 

 Ap]Dlying the results of physical chemistry to the differentiation 

 of rock-magmas, you have indicated a manner in which a separation 

 of the alkaline and calcic portions might be brought about, and 

 you were the first to draw attention to the correspondence of the 

 distribution of these types Avith areas characterized by the Atlantic 

 and Pacific types of coast-line. Your work on the ' Xatm-al 

 History of Igneous Rocks ' and your addi*esses to the British 

 Association and to this Society have all been important contribu- 

 tions to theoretical sreolosrv. For these reasons the Council has 

 accorded to you the Wollaston Medal, in recognition of those 

 manifold services, by which you have advanced our knowledge of 

 the mineral structm-e of the Earth, both in the nan*ower and in the 

 more extended meaning of the words. 



Dr. Haekee replied in the following words : — 



Mr. Peesidext, — 



I wish to express my keen appreciation of the distinction which 

 has been conferred upon me, and to record my thanks to the 

 Council for their generous estimate of my merits. To so high an 

 honour I have never ventured to aspire. If a perusal of the list of
