286 Obi/nar//— Professor R. S. Tarr. 



that in 1881, when it was brought forward by Mr. Henry Stopes at 

 a British Association meeting, it was considered ivrong to suggest that 

 man could have been alive at so early a date. Mr. Stopes was 

 therefore content to wait till further evidence came to hand before 

 bringing it before a wider public ; but his early death left his work 

 unfinished, so the shell has never been figured. 



The accompanying illustration is from a photograph and indicates 

 the natural size of the shell ; it shows clearly most details of its 

 features except the coloration. It should be noted that the excavated 

 portions are as deeply coloured red-brown as the rest of the surface. 

 This is an important point, because when the surfaces of Red Crag- 

 shells are scratched they show wliite below the colour. It shoi;ld 

 also be noticed that the shell is so delicate that any attempt to carve 

 it now would merely shatter it. 



As, however, the question is still so much under discussion, I wish 

 to do no more now than give a good illustration of the most interesting, 

 though controversial, specimen, so as to make its appearance and 

 detail known to all interested in it. lieferences to the literature 

 will be found in my note in the Geological Magazine for Eebruary, 

 1912, pp. 95-6.

RALPH STOCKMAN TARR. 

 Born 1864. Died March 21, 1912. 



The sudden death of R. S. Tarr on March 21 last at the early age 

 of 48 has been deeply felt by his many friends on this side of the 

 Atlantic, who held in high regard his sterling personal qualities, as 

 well as his scientific ability. 



Born at Gloucester, Mass., Professor Tarr entered at Harvard in 

 1881, and after interruptions for practical work in marine zoology and 

 for geological field-work in the Eastern and Western States, he 

 graduated in 1891, and in 1892 was appointed Assistant Professor of 

 Dynamic Geology and Physical Geography at Cornell University, and 

 Professor of the same subjects there in 1896, occupying the chair of 

 Physical Geography up to the time of his death. He was married in 

 1892, and leaves a widow and two children. 



In 1896 Tarr had charge of the Cornell expedition to Greenland, 

 which did excellent work; and in 1909 and 1911 he, conjointly with 

 Professor Lawrence Martin, carried out the research expeditions of 

 the National Geographic Society for the study of Alaska glaciers. 

 In 1910 he participated in the Geological Congress excursion to 

 Spitzbergen. 



In his university Professor Tarr was recognized as an inspiring and 

 sympathetic teacher, and his untimely death has called forth many 

 touching tributes to his memory from his former students. He was 

 the author of numerous papers and memoirs on physiography, glacial 

 geology, and educational topics, the best-known in this country being
