eggs of insects, and amongst them he got some of the eggs of the Lady, 

 bird. He put them for two hours or more into alcohol to kill them, and 

 then mounted them in Canada balsam. Looking at the slide some time 

 afterwards, he found that the whole of the eggs had hatched. The larvae 

 on the slide which he presented to the Cabinet were some of this batch ; 

 they were mounted in balsam ; and he mentioned the matter as it was a 

 carious fact that these creatures should have resisted the efforts made to 

 destroy them in the manner described. 



The President read a letter from the Secretary of the Croydon Micro- 

 scopical Club, announcing that their Soiree would be held on Wednesday, 

 the 24th of November, and asking the co-operation of members of the 

 Quekett Microscopical Club on that occasion. 



The President exhibited some button-moulds, brought by Mr. Simpson, 

 of Ealing, for use as cells for dry mounting. They appeared to be very 

 well made, and likely to be useful, and certainly had the recommendation 

 of being extremely cheap. 



Mr. Hailes said there was nothing new about them, as he had used them 

 for years for the pui-pose. 



The President read a short "paper " On a Simple Growing Slide," which 

 he exhibited in illustration. 



Ml'. Ingpen described the use of Zeiss's adjusting objective for low powers 

 (called " a* " in Zeiss' Catalogue), practically illusti-ating his remarks by 

 the exhibition of the apparatus. 



The President called attention to some objects exhibited by Mr. J. D. 

 Hardy. They were specimens of " Pond life," and appeared somewhat 

 uncommon. 



Mr. Hardy said that one of these was a species of Yaginicola ; it was in 

 a very different condition from anything he had been able to find figured 

 or described. It had been very abundant in his pond during the year, ap- 

 pearing in groups of 50 or more tubes. He had thus been able to trace 

 something of its life-history. It first appeared in pairs of very small bright 

 tubes attached to the weed. From every tube a very slender cilium was 

 thrown out on each side. It then developed a heart-shaped ciliated disc. 

 Sub-division then took place until the group was formed, which, on arrival 

 at maturity, became detached from the weed, aud floated away in the 

 water, revolving very slowly. It appeared to be most nearly allied to 

 Vaginicola grandis. He promised to send drawings for insertion in the 

 Club portfolio. Mr. Hardy also referred to a specimen of Melicerta tyro, 

 which he was exhibiting, mentioning particularly its inability to construct a 

 case, and the size and prominence of its two antennce. 



The President enquired if Mr. Hardy had detected anything like tlio 

 usual valve, and observed that Vaginicola usually had a vase-shaped 

 tube, and he thought the specimen just described was hardly like one of 

 that genus. Certainly it must be a very uncommon variety. 



Mr. Hardy thought that the variety to Avhich the President alluded was 

 marine. 



The Px'esident thought this was a case in which a growing slide would be
