MICROSCOPICAL SOCIETY.

The next change was in May, 1859, when W. K. Bridgman, 
who had till then made all the arrangements for the Society, 
desired to resign the Secretaryship, and J. Mottram was appointed 
in his stead. 
Francis Sutton, p.i.c. [Council, 18G7], well known by the work 
on Volumetric Analysis which bears his name, and for his practice 
as a chemist and analyst, added greatly to the interest of the 
meetings by his practical knowledge as applied to the subject 
matter of the Society. 
About this time Rev. William Cufaude Davie, M.A., of Cringle- 
ford, and Charles Mends Gibson, M.R.C.S. (d. 1871), [Council, 
18G6 — G9], joined the Society. 
In 1 8G2 the presentation by Mr. Brightwell to the Society of 
his instrument and cabinet of objects necessitated its reconstruction 
under more definite rules, and with a small share capital of £2 
per share, and an annual subscription. 
On the 2Gth September in that year, at a meeting at Mr. 
Brightwell’s, he made some remarks on the nature of his collection 
of slides, and then formally handed them and the microscope to 
the Society. On the 3rd October the Secretary superintended 
their removal to the rooms of the Literary Institution in 
St. Andrew’s, where, by permission of that body, a large cupboard 
cabinet had been placed for their reception, and, from this time 
forth, the host of each monthly meeting arranged for the appear- 
ance of the microscope on his table, and for its return. In after 
years, at various dates, two micro-slide cabinets holding 1000 each, 
a micro-spectroscope, and a micro-lamp were purchased. 
For some years (1869 — 1876) the ‘ Monthly Microscopical 
Journal ’ was taken and circulated amongst the members, and these 
volumes are now in your own library. In 1S72 a 1 - 10th immer- 
sion object glass was obtained, and in 1873 the instrument was 
converted to a binocular. 
In the spring of the year 1863 a microscopical evening was held 
by invitation, in the rooms of the Literary Institution, courteously 
granted by the Committee of that body for the occasion. More 
than one hundred of the friends of the members were present, and 
twenty-one instruments were placed on the table, with the result 
that a most enjoyable evening was spent. 
The same course was pursued in 1861 and 1866 with a like
