certain reticulations which occurred in Pro'ococcus pluvialis when stained 

 with osmic acid. There seemed to be no structure until they were stained, 

 and then surrounding the nucleus were seen what looked like fine canaliculi. 

 Mr. Gilburt said he had observed this feature in Protococcus, but did not 

 think it was altogether the same as the President had described ; he thought 

 the reticulations were simple protoplasmic filaments which acted as guide 

 ropes to keep the nucleus in the centre. 



Mr. Stewart said he quite agreed with this view ; they had their parallel 

 in the lines of Volvo x by which they were kept in position. 



The thanks of the meeting were voted to Mr. Gilburt for his paper. 

 Announcements of meetings for the ensuing month were then made, and 

 the proceedings terminated with the usual Conversazione, at which the fol-
