sion in water. After tracing its development, Dr. Henderson 

 gave several instances of the effect of the poison in bites by 

 water snakes. 



Mr. Ales. Patience read a paper entitled " Note on the 

 occurrence of the Schizopod, Macropsis slabheri (van Beneden), 

 within the Clyde Sea Area," and exhibited specimens of this and 

 of some other species of Schizopods. He stated, " I obtained 

 two specimens (a male and a female), by means of the tow net, 

 while dredging off Aoidh Rock, Loch Fyne, in about 34 fathoms. 

 In the same tow-netting were quite a number of specimens of 

 another mysid, viz., Schistomysis ornata (G. 0. Sars). M. 

 slabheri is characterised by enormously developed eyes, elevated 

 on extremely long and nearly cylindrical eye-stalks. It is 

 distinguished from all others of this family by the structure, 

 in the males, of the first antennae. At the apex of the peduncle, 

 besides the two flagella and the usual setose appendage, there 

 is a fourth appendage, which consists of a long narrowly conical 

 basal process, ending. in a very long seta. The telson is short; 

 its extremity projected beyond the lateral margin in a triangular 

 form; the apex, however, is rounded. This schizopod has been 

 recorded from the Firth of Forth, and also from Falmouth. In 

 a letter from my friend, Dr. Thomas Scott, F.L.S., of H.M. 

 Fishery Board, he informs me that it has been taken from the 

 stomach of a fish captured in the Solway Firth. I have now to 

 record its occurrence in Clyde waters." All the more important 

 features of Macropsis were shown in a blackboard sketch. 



Mr. Peter Macnair, Keeper of the Natural History Collections 

 in the Glasgow Museum, read a paper on " The Alpine Flora of 

 the Scottish Highlands, and the Geological Factors in its Origin 

 and Present Distribution." The lecture was beautifully illus- 

 trated by lantern slides showing Scottish alpine scenery and 

 alpine plants, photographed in situ. At the outset he referred 

 to the history of the discovery of these plants in the Scottish 

 Highlands, and to the work of such early observers as Stuart 

 amongst the Breadalbane Mountains, and Don in the Clova 

 district. A number of plants were shown that had been 

 gathered by Don about the beginning of the last century, which 

 had recently been presented to the Kelvingrove Museum. 



The general character of the alpine flora of the Scottish
