Walter Ibbotson Beaumont. 



Many workers at the riyniouth Laboratory will have heard with 

 deep regret of the death of Mr, Beaumont, who was accidentally 

 drowned whilst yachting at Tarbert, Loch Fyne, on May 3rd, 1912. 

 Mr. Beaumont first came to Plymouth in 1895, and from that time he 

 spent several months of each year at the Laboratory. He had com- 

 menced the study of biology under the late Professor Milnes Marshall, 

 in Manchester, and subsequently went to Cambridge, where he entered 

 Emmanuel College. He was chiefly interested in faunistic work, and 

 contributed valuable papers on nemerteans, schizopods, and nudibranchs 

 from Port Erin, Plymouth, and Valencia. He was also a keen student 

 of bird-life, and did much useful work in connection with bird-marking 

 and bird migration. 



George Herbert Grosvenor. 



Mr. Grosvenor will always be remembered by a large number of 

 younger English biologists from the fact that for a number of years 

 he conducted the annual Easter Vacation Course in Marine Biology at 

 the Plymouth Laboratory, and it was under his guidance that they 

 obtained their first acquaintance with the wealth of living creatures 

 that are found in the sea. He was a man of a singularly cheerful and 

 attractive disposition, a keen observer, and an enthusiastic naturalist. 

 His principal contribution to marine biology was the paper in which 

 he demonstrated that the nematocysts of nudibranchs are derived 

 from the hydroids upon which they feed. Latterly Mr. Grosvenor 

 worked chiefly at agricultural entomology in connection with his post 

 of lecturer in that subject at Oxford. Mr. Grosvenor was drowned 

 whilst bathing at Polzeath, in Cornwall, on September 4th, 1912, in an 

 attempt to help a companion who was in difficulties.
