OBITUARY. 



WILLIAM GRAY. 



The death, in liis eighty-sixth year, of Mr. Wilham Gray, removes one 

 of the pioneers of the Belfast NaturaHsts' Field Club, and one of the 

 most familiar figures in scientific circles in Belfast. Mr. Gray belonged 

 to the period when a " naturalist " v.as expected to know something of 

 the whole range of science, and he acquired a wide knowledge of local 

 geology, zoology, and archaeology. But detailed study did not appeal 

 to him, and though he collected extensively and had a very complete 

 knowledge of the district in which he lived and worked, he contributed 

 but little to scientific literature during his long and active life. This is 

 to be regretted, as for many years his position as inspector under the Board 

 of Public Works gave him exceptional opportunities for scientific study 

 throughout the counties of Antrim and Down. He was much esteemed 

 by his fellow-members of the Belfast Naturalists' Field Club who 

 elected him as President for the years 1879-81 and 1889-91.
