410 PROCEEDINGS OF THE SOCIETY. 



The Chairman was sure the Fellows present would be very pleased 

 to return their best thanks and congratulations to Mr. Sheppard for his 

 excellent paper, so full of instruction and comment. As he had 

 previously pointed out, these original investigations involved a great 

 deal of work and much continued energy which were in no way commen- 

 surate with the length of a paper ; indeed, in one instance with which 

 he was acquainted, the summary of five years' close work was condensed 

 into but little more than a sheet of foolscap. It was not easy to pass 

 remarks on any new matter without reading the author's remarks in the 

 Journal, so he had but little to say upon the subject in question, but he 

 felt sure those present would show their esteem in the usual manner. 



The thanks of the Society were unanimously voted to Mr. Sheppard 

 for his paper. 



Mr. Heron-Allen said he had found in his slide box, a slide which 

 had been made to illustrate a paper recently read by himself and Mr. 

 Arthur Earland before the Quekett Microscopical Club, and which he was 

 glad to be able to show on the screen, as it represented the most remark- 

 able powers of selection of material hitherto encountered in the study 

 of the arenaceous Foraminifera. It represented a new species called 

 Technitella Thomsoni (Earland), dredged by Mr. Earland in the Moray 

 Firth. In this case the creature had formed its test entirely of the 

 spicules of a particular kind of Echinoderm, and though there were no 

 doubt plenty of these at the bottom of the sea in proportion to the 

 grains of sand and other material to be found in the same area, the 

 number of these plates was infinitesimal ; yet this Rhizopod went about, 

 and in the most remarkable way, selected only these for its purpose. 

 The slide in question was then shown upon the screen. 



Mr. J. W. Gordon said he should like to mention that the next 

 meeting of the " Brass and Glass " section would take place on the 28th of 

 April, when Mr. Cheshire had arranged for a demonstration of the 

 optica] parts of a Petrological Microscope, and contributions of apparatus 

 relating to this branch of microscopy would be particularly valuable on 

 that occasion. 



It was announced that at the next Ordinary Meeting of the Society, 

 on May 10th, there would be an exhibition of "Pond Life."
