such as diphtheria and scarlet fever, which seemed rather risky 

 to the uninitiated, and also a " Cambridge " rocking microtome, 

 which was kept busy cutting sections during most of the 

 evening. Dr. Thompson had a number of tests for colour 

 vision and optical illusions in colour — one gentleman amongst 

 those experimented on proved completely colour blind — also an 

 ingenious method of measuring small spaces of time, and a pulse 

 recording instrument. 



Dr. Cecil Shaw's microtome came in for a good deal of 

 attention, partly because it was engaged in the gruesome work 

 of slicing a human eye. 



Professor Symington's exhibit was an apparatus for drawing 

 pictures of sections under the microscope, also the structure of 

 nerve cells, with micro-photographs by J. J. Andrews, L.D.S. 



The following members also showed the exhibits here 

 detailed : — Rev. John Andrew, President of the Micro. Section, 

 general subjects; Miss Mary K. Andrews, sections ol rocks; J. C. 

 Carson, microscopes and microscopical apparatus; J. H. Davies, 

 specimens of flax injured by the rat-tailed maggot, larva of 

 drone-fly (Eris/a/ts), also specimens of the insect ; W. D. 

 Donnan, M.B., living specimens of infusorians and rotifers; W. 

 B. Drummond, M.B., CM., microscopic sections illustrating 

 marine life; W. A. Firth, diatoms; P. F. Gulbransen, pond life; 

 the Rev. H. W. Lett, A.M., structure of mosses and hepatics, 

 with specimens ; H. M'Cleery, Hydrozoa and Polyzoa ; W. S. 

 M'Kee, living illustrations of microscopic forms of fresh- water 

 organisms ; A. Speers, B.Sc, Lond., structure of vegetable 

 tissues ; James Stelfox, C.E., living illustrations of microscopic 

 forms of fresh- water organisms ; William Swanston, F.G.S., 

 Echinodermata. 



In addition to the microscopical exhibits there were two 

 series of lantern displays, at 8-30 and 9-30, from photos 

 taken on the Galway and other excursions. The first of 

 these was described by W. Gray, and the second by W. 

 J. Fennell, who pointed out the features of the pictures, 

 which were excellently shown by Lizars' lantern. On each
