NATURAL HISTORY SOCIETY OF GLASGOW. 67 



genus Solenocaris, which had been collected by Mrs Robert Gray, 

 from the Silurian strata near Girvan; a remarkable series of 

 fragments, found in the same locality by Mrs Gray, and wliich 

 the speaker was inclined to consider as appendages of a Trilobite 

 or Limulid crustacean; and lastly, a specimen of the Tench 

 {Cyprinus tinea), from Lochlomond. This specimen gave rise to 

 some conversation, but no one could give information as to the 

 introduction of Tench into the loch. Mr Hadaway some time ago 

 informed Dr Young that one had been caught by two members 

 of the Angling Club near Balmaha, and that an individual captured 

 in the spring had been kept alive in the neighbourhood ; the 

 latter, forwarded by the Rev. W. Macintosh of Buchanan, being 

 that shown to the Society. It was stated that the recently caught 

 fish had been taken by the net, but that one had been taken with 

 bait some years ago. Mr John Young, F.G.S., said that in a cut, 

 near the Kelvin, in Gadder Park, Tench had been found living 

 some years ago, having been introduced by a former Mr Stirling 

 of Gadder. Yarrell does not mention its occurrence in the West 

 of Scotland. 



Mr John Young exhibited a further series of specimens of 

 polyzoa, shells, etc., which he had collected from the glacial clays 

 at Gartsdyke, a deposit in wliich he, Mr D. Robertson, F.G.S., and 

 others, had found over eighty species, some of them identical with 

 those from the English Grag. The carefully-selected series he 

 showed was presented to the Hunterian Museum. An animated 

 conversation ensued, in which Mr J. Thomson, F.G.S., Mr Goutts, 

 and others took part, the natural or artificial disturbance of the 

 beds being the chief points at issue. 



Dr Young, in exhibiting the specimens purchased from 

 menageries, stated the ca.use of death in each case, insufficient food 

 and imperfect protection from cold being the chief causes ; while 

 in the case of the monkeys, neglect of the most obvious sanitary 

 precautions had also to be considered. In connection with this 

 subject he referred to the mortality of cats in autumn, and denounced 

 the brutality too common of turning them adrift when families 

 leave town for the holidays. He suggested the imposition of a 

 tax on cats, if that would be found practicable, not for fiscal 

 purposes, but to diminish the cruelty practised on these animals, 

 and because vagrant cats were, he believed, agents in the spread 

 of infectious diseases.
