PROPOSED MICROSCOPICAL SOCIETY FOR CARLISLE, pat fi § 
up the edges to form a sort of dish, coat its face with thin collodion, 
and allow to dry. 
Immerse the plate and the coated tissue in cold water, when 
the latter has become limp, place it on the glass under water, 
avoiding air bubbles, and force into contact with the squeegee, 
allow it to remain for a few minutes, then put into warm water, 
strip and develope as previously described—immerse in alum 
solution and wash well with cold water. 
When dry, the picture should be covered with another piece of 
clear glass the same size, the two being prevented from touching 
by very small strips of card fastened by gum to two of the edges, 
the whole bound round with thin black paper and the slide is 
completed. ‘These pictures when laid upon white paper should 
only allow the paper to show through in the very highest lights, 
just a patch of white here and there. 
Should the picture not be sufficiently vigorous, it can be easily 
made as intense as may be desired, by pouring over it, before it is 
allowed to dry, a three-grain solution of pyrogallic acid, to which a 
few drops of nitrate of silver solution are added in the same way 
that a negative is intensified.”

MEETING of gentlemen in the study of microscopy was held 
on Wednesday night, April 13th, in the County Hall, for the 
purpose of taking into consideration the question of forming a

and, subsequently Mr. Hepworth, (Mr. Ferguson having to leave) 
Carlisle, presided; and among others present were Mr. Hall, 
surgeon; Dr. Maclaren, Dr. Carlyle, Dr. Barnes, Dr. Macdougall, 
Dr. Campbell, Dr. Russell. Mr. W. Brown, surgeon; Mr. R. J.

Tom Duckworth, Mr. W. Duckworth, Mr. Sinclair, Mr. Hill, Mr. 
Hands, Mr. Dodd, Mr. James Young, Mr. Halton, and the Rev. 
Charles Dowding, curate of Dearham. Mr. Hall brought the sub- 
ject before the meeting in a few prefatory remarks. He said an 
attempt had been made on a previous occasion to form a Micros- 
copical Society in Carlisle, but he believed it was a failure. Nothing 
daunted by that failure he determined to take steps with a view to 
the formation of another Society. He had written to several 
gentlemen to ascertain their feeling about it, amongst others to 
Colonel Salkeld, who expressed a willingness to become a member 
of a Society, if formed; and to the Rev. Canon Carr, Dalston,
