PROCEEDINGS OF THE SOCIETY. 125 



Miss Pankerd, Dr. Ruggles Gates and Mr. Beer also spoke. 



Mrs. Arber, in reply, said there was a nuclear lobing that occurred 

 in young cells, and, in addition, she had unfortunately used the word 

 " lobing " for the irregular forms developed by very old nuclei. This 

 perhaps accounted for the disagreement pointed out by Mr. Paulson. 

 With reference to the nuclear pseudopodia breaking olf, she would like 

 to know whether Mr. Sheppard had evidence of their actual detach- 

 ment. She had always found that they were joined by a little bridge. 

 That was what had puzzled them. At the present time there appeared 

 to be some doubt about most of the botanical cases described under the 

 name " amitosis." 



The President proposed a very hearty vote of thanks to Mrs Arber, 

 and it was carried by acclamation. 



Mr. Akehurst gave an exhibition of Professor Silverman's Illuminator 

 for Opaque Objects. 



Mr. E. J. Sheppard exhibited a slide showing Mitosis in Hyacinth 

 root-tips, with marked differentiation in the staining of the chromosomes. 



Mr. F. Martin Duncan exhibited a slide of Cladonoma radiatuniy 

 a Medusa narcotized by the Menthol Crystal method. 



Mr. Wilson exhibited specimens of Floscularia ornata. 



Mr. Scourfield exhibited a specimen of Diaptomus Castor. 



Votes of thanks were accorded to the above for their exhibits. 



The President announced that the next Meeting would be held on 

 March 17, and the next Meeting of the Biological Section on March 3, 

 when Dr. Tierney would read a communication on "The Bacterial 

 Flora of Water." 



The business proceedings then terminated.
