PROCEEDINGS OF THE SOCIETY. 579 



circumstances. He had tried himself some similar experiments, and 

 thought he had succeeded in infecting Musca vomitona, but it might be 

 well to remark that in one hive bee he had found eight or ten distinct 

 kinds of bacilli, one of which had a distinct curvature. Amongst bee- 

 keepers there used to be an idea that the bees had no diseases, although 

 there was one affecting the larvae, but directly a careful examination 

 of the bees was made it was found that they were subject to a great 

 many. One kind had the curious effect of causing all the hairs to 

 fall out, and on examining bees which were so affected he found them 

 all to contain large numbers of the short red bacillus. If any one 

 intended to experiment in these matters, it might be useful to know 

 that if the bees were fed with food stained with anilin dyes very 

 curious effects were produced upon the internal organs, differentiation 

 took place within the body, and when they came to dissect them after- 

 wards they would find it a very great help. 



Mr. Crisp announced that the Council had decided to place one 

 of Prof. Abbe's Apertometers in the Library for the use of any of the 

 Fellows who might wish to test the apertures of their objectives. 

 Also that it was intended to publish in the Journal in future portraits 

 of the Presidents of the Society. It was also contemplated to publish 

 the portraits of past presidents, but as it would be quite impossible 

 to give whole-page plates of the whole eighteen, it was intended to 

 give one of Prof. Owen as the first President of the Royal Micro- 

 scopical Society of London, and another of Mr. Glaisher as the first 

 President of the Eoyal Microscopical Society after the Charter, the 

 others being printed in two groups. To enable this plan to be car- 

 ried out, they would be glad if any Fellow of the Society who had 

 photographs of either Dr. Lindley, Mr. Jackson, Dr. Lankester, Mr. 

 Farrants, or Mr. Eeade, would lend them for the purpose of being 

 copied. 



Dr. J. D. Cox's paper, " Structure of the Diatom Shell. Siliceous 

 films too thin to show a broken edge," was read (supra, p. 398). 



Mr. E. Wethered read his paper " On the Structure and Origin of 

 Carboniferous Coal Seams " {supra, p. 406), the subject being illus- 

 trated by large diagrams, as well as by numerous preparations exhi- 

 bited under Microscopes. 



The President said he should only be expressing what he was sure 

 would be the feeling of the whole of the Fellows present, in thanking 

 Mr. Wethered for his very interesting paper. 



Dr. Hudson's paper " On four new species of the genus Floscularia, 

 and five other new species of Eotifers," was read. The paper described 

 F. mira, F. mutahilis, F. calva, F. edentata, ConocJiiliis dossuarius, 

 Notommata spicata, Stephanops armatus, Pompholyx sulcata, and 

 Taphrocampa ocellata.
