November 7th, 1881. 
Alfred Brothers, F.RA.S., President of the Section, 
in the Chair. 
A letter was read by the Secretary from Mr. Arthur 
Latham, in acknowledgement of the resolution of condolence 
on the death of his father, passed at the last meeting. 
The following resolution passed at the council meeting of 
the Parent Society on 19th April was read : 
“ On the motion of Mr. R. D. Darbishire, seconded by Dr. 
Joule, it was resolved that the Associates of each Section be 
empowered to vote in the election of officers of the Section 
with the members, and that Associates may be eligible for 
the offices of the section.” 
The Secretary read a communication from Mr. Side- 
botham, F.L.S., relative to a supposed marine species of 
alga (? fucus canaliculatus or ceranoides) which was growing 
on the window of his house at Bowdon. It was about half 
an inch in diameter, but was still increasing in size. It 
might have originated from a spore blown by a west wind, 
and nurtured by the saline breezes that blow across from 
the Irish Channel through Runcorn Gap. 
Mr. Hartog, B.Sc., F.L.S., made some remarks on the 
result of his further investigation of the mode in which 
hydra viridis swallows its food. He had found that the 
endoderm cells of the tentacles possess a power of amoeboid 
motion by means of which they draw themselves over the 
object to be swallowed.
