COUNCIL FOR 1892.

March meeting, Mr. H. D. Taylor illustrated by means of some 
views of Welsh scenery, the advantages of using iso-chromatic

First and foremost should be mentioned a beautiful specimen 
of Baillon’s Crake (Porzana Baxlloni), the death of which is 
thus recorded in the “ Naturalist” for October, 1892, by the 
Departmental Curator, as follows :— 
“ Year by year numbers of birds fall victims to the telegraph 
“ wires, and if these ‘ Patent Guillotines’ continue to multiply 
“ as they are doing at present, many more casualties will
