tion of making a model from the design of Mr. Burch, and of presenting 

 the same to the Club. 



The Chairman said that this very clever invention was calculated to 

 promote what every microscopist should do, namely, draw everything to 

 scale. It appeared to be an ingenious attempt to make one eye do what 

 had formerly been done by both. He had much pleasure in moving a vote 

 of thanks to Mr. Curties for reading the paper, and would beg him to 

 convey the thanks of the Club to the gentleman who had been at the 

 trouble of elaborating it. 



Mr. Ingpen said that he had an interesting paper to read by Mr. Stani- 

 forth Green " On Insect Mounting." Mr. Green had x-esided some years in 

 Ceylon, and made good use of the opportunities there afforded to him of 

 collecting and mounting insects. He was one of the first to mount them in 

 the solid, and to protest against the ordinary method of compressing them, 

 and he now gave them his process of mounting and preserving. The paper 

 was then read to the meeting. 



Mr. Thomas Spencer wanted to know what the Anti-Vivisectionists 

 would say to the paper, because the insect must, of course, be killed before 

 they commenced to operate, and it was probably killed rapidly by the action 

 of the turpentine. 



Mr. Ingpen said that most insects were killed instantaneously by placing 

 them, in turpentine ; one of the quickest means of killing them was by 

 plunging them into boiling water. 



The Chairman could assure Mr. Spencer that turpentine was an un- 

 doubted anaesthetic, and therefore no doubt these insects died happily. He 

 had often prescribed turpentine to patients to be used as an outward appli- 

 cation, and had ascribed its beneficial effect not so much to its action as a 

 counter irritant as to its anaesthetic effect upon the patient. 



Mr. Spencer said he had no doubt that death was quick, and what they 

 might call instantaneous ; but what might be to a human being only half a 

 second of time might be half a minute to the insects. However, he only 

 spoke of the matter philosophically. 



Dr. Matthews was very glad the subject of mounting insects in their 

 natural condition was receiving attention ; he himself had been almost one 

 of the first to protest against the process of squashing them. 



Mr. Ingpen thought it important that they should get all the informa- 

 tion they could on the subject, especially with regard to getting specimens 

 from foreign parts with the least amount of injury. The extremely 

 beautiful manner in which objects mounted by Mr. Green's plan were 

 shown by the paraboloid, the perfect condition of the trachea, eyes, and 

 muscular tissue, rendered this process a matter of the greatest interest. 



A vote of thanks to Mr. Staniforth Green was unanimously carried. 



Announcements of meetings and excursions for the ensuing month were 

 then made, and the proceedings terminated with a conversazione, at which 

 the following objects were exhibited: — 



Tongue of Honey Bee Mr. F. W. Andrew. 



Shell of Haliotis sjplendens Mr. A. L. Corbett.
