Mr. Suffolk exhibited Ja collecting bottle with flat sides, which 

 had been ground and polished. Every one must have found the 

 inconvenience of the ordinary round bottles through which it was 

 impossible to see anything clearly, and therefore would welcome one 

 which had flat sides worked to a true surface, through which an

Prof. Stewart said they had almost ceased to use these bottles 

 at the College of Surgeons because the sides were so rough and the 

 tops so far from flat as to be of very little value. The first samples 

 were very much better, but the . later ones were so bad as to be 

 practically useless. 



Prof. Stewart called attention to a specimen he exhibited under 

 the Microscope, showing the special eyes of Chitonidse described by

 but having found at the College of Surgeons a better specimen than 

 the one from which Prof. Moseley 's model had been made, he had 

 brought it to the meeting. A section showed that the shell was 

 raised into nixmerous corneal elevations beneath which it was
