MICROSCOPICAL AND NATURAL HISTORY SECTION. 
2nd November, 1880. 
Alfred Brothers, F.R.A.S., President of the Section 
j 
in the Chair. 
Mr. E. Ward exhibited some microscopic slides containing 
vegetable sections double stained. 
O 
Mr. Thomas Rogers exhibited specimens of Chiton sca- 
bridus (Jeffreys), from Jersey, collected by Duprey. It 
appears to be rare. Dr. Jeffreys thought at first that it 
might have been a variety of Ch. cancellatus, but the ar- 
rangement of the sculpture, and its somewhat different form, 
lead him to believe it quite distinct. Mr. Duprey finds it 
under stones, along with C. cancellatus, Rizzoa lactea, R 
striatula, and Adeorbis sub-carinatus. 
Mr. Thomas Rogers also exhibited a prepared section of 
the palate of an African species of Ampullaria, which had 
been shown in a living state at the last meeting of the 
Section. 
Prof. W. C. Williamson, F.R.S., exhibited a large mass 
of one of the Nidularise from Mr. H. D. Pocliin’s estate in 
North Wales. Also some slides of Ascobolus, in various 
stages. 
Prof. Williamson explained the bisexual reproduction of 
one of the the fresh water Vaucheriee. 
Dr. John Tatham, through Mr. Bailey, submitted a form 
of erecting microscope designed by Mr. Stephenson, which 
worked very well when used for dissecting. 
Mr. T. H. Birley read a paper explantory of the process 
adopted by Herr Herpell, of St. Goar, in preparing specimens 
of Hymenomycetous Fungi.
