characteristics of the true (7. frigida, as compared with those 

 of the so-called Scottish C. frigida, and concluded by saying, 

 " I cannot find that there is any ground for believing that the 

 Swiss frigida is represented in this country, but I am con- 

 vinced that, if carefully examined and compared, the so-called 

 Scottish frigida will be found to be a variety of the well-known 

 C. binervis." 



Dr. Johnstone Macfie read a paper entitled " List of Birds

 Mackay, Woodbourne, Giffnock, were elected Ordinary Members 

 of the Society. 



Mr. T. N. Johnston, M.B., CM., delivered a lecture on " The 

 Bathymetrical Survey of the Scottish Fresh-water Lochs." The 

 lecture, which was fully illustrated by a very beautiful series 

 of photographs shown on the screen, entered with detail into 

 the elaborate work which the Survey is attempting in mapping, 

 sounding, and thoroughly exploring all the fresh-water lochs of 

 Scotland. The temperatures at various depths, seiches, currents, 

 bottoms, flora, fauna, and chemical constituents of the lochs are 

 all being investigated, and a full and interesting description was 

 given of the work already accomplished. Sounding and other 

 apparatus used by the Survey were also exhibited. 



Mr. James Murray, who had arranged to read a paper, " Notes 

 on the Pelagic Life of the Lochs," gave a few details of the 

 practical results of the investigations in the faunal department 

 of the work, but, on account of the lateness of the hour, was 

 obliged to postpone the reading of his paper to a future 

 occasion. A very cordial vote of thanks to the lecturer, Dr. 

 Johnston, was moved by Professor Barr, and warmly accorded 

 by the large audience present.
