 with Mr. Tait he collected a new fish-fauna from the Downtdnian 

 rocks of Lanarkshij-e, which, in the words of Dr. E. H. Ti-aquaij-. 

 opened out a new vista in the field of Palaeozoic ichthyology. 

 Mr. Tait. bv his investisration of the Ehvnie chert-band, was able to 

 establish conclusively its true age as Old Eed. and the investigation 

 of his collections has thi-own much light on the problems connected 

 with this oldest land-flora. I have referred briefly to the more 

 outstanding: of their individual conti-ibutions to knowledsre, made 

 during a long and devoted service, which has yielded a large body 

 of material for detailed iuvestisration bv others. In recosrnition of 

 this, I ask you to accept and ti-ansmit these awards to their 

 respective recipients in the name of the Geological Society of 

 London.
