Megaceros of the extinct mammals, and it co-existed with man." 

 This from "The Intellectual Observer." Stewart adds "Therefore 

 I infer that Megaceros was likely contemporaneous with Man." 

 (There seems evidence in the Ballynamintra Cave deposits that 

 this was so, but Dr. Scharff does not consider the evidence con- 

 clusive in the case of the Clare Caves ; though he does so for the 

 Bear, which lived long after the " Irish Elk" and Reindeer had gone.) 

 From "Science Gossip" he has memos on "Sociable Mites 

 infesting various Plants," "Gall Insects and Oak-Buttons," "Death 

 of Native Birds in New Zealand caused by the introduction of 

 Bees," and on "Parasites," "Courtship of Birds," and other 

 subjects from "The Student." 



There are many additional notes from the "Annals of Natural 

 History," "Proceedings of the Royal Irish Academy," and other 

 scientific journals, mainly connected with Marine Zoology, in 

 which he seems to have been rather more interested than in the 

 land fauna. About 1868 he was engaged in dredging on the 

 Antrim and Down coasts, on the 20th June from Bangor to 

 Donaghadee in 6 to 8 fathoms, later in Belfast Lough in from 8 

 to 15 fathoms, and in September for two days at Glenarm with 

 Dr. Holden. He lists chiefly Shells, Star-fish, Urchins, and 

 Zoophytes, the latter mainly from Belfast Lough, where he seems 

 to have determined 17 species. This work proved very useful in 

 the compilation of the lists published in our Guide, prepared for 

 the 1874 Belfast Meeting of the British Association. I am glad 

 to say some of Mr. Stewart's collaborators in that work are with 

 us tonight, still active in our Club work, though thirty-seven 

 yi ;irs have passed since then. 



His finding of Helix personala, a foreign land-shell, on the 

 sand-hills at Newcastle, Co. Down, in 1870, gave rise to much 

 discussion in some scientific journals afterwards. 



His good knowledge of Mollusca and of local marine life 

 generally, must have been of service to him in determining the 

 species for his "List of the Fossils of the Estuarine Clays of Down
