PROCEEDINGS OF SOCIETIES.

Scientific Evening, November 8, 1876. 
On Wednesday evening, November 8, a conversazione was given 
by the Eoyal Microscopical Society, the library of King's College 
having been kindly placed at its disposal by the authorities. In 
every sense of the word the evening was a complete success, the 
objects exhibited being at once interesting and rare, and, as will be 
seen by the annexed list, being both numerous and varied. There 
.were about a hundred present, and there was hence abundance of 
room, and everybody was enabled to examine the different specimens 
exhibited with ease and comfort. 
The thanks of the Society are especially due to Mr. How and to 
Mr. Charles Baker for the loan of the lamps, which were a great 
acquisition to the exhibitors of objects. Among the special things 
exhibited by the Society may be mentioned the Quekett Medal, which 
it is proposed to bestow on certain lecturers selected by the Council 
of the Society, and which really looked remarkably well. 
Tea and coffee were served in the course of the evening, and 
altogether the gathering may be said to have been one of the most 
successful that have been held at King's College. 
Objects Exhibited. 
Messrs. Beck : New form of achromatic condenser, and crystallized 
gold, &c. 
Mr. John Browning : Sorby's improved micro-spectroscope, with 
new measuring apparatus ; the McLean star spectroscope, requiring 
no slit and used like an ordinary eye-piece ; also table polariscope. 
Mr. Brindley : Sections of boulders from the glacial clay. 
Mr. Baker : Bramhall's illuminator. 
Mr. T. Curties : Seminal glands of flea. 
Mr. W, Cocks : Lacinularia socialis and Carcliesium polypinum. 
Mr. F. Enock : Stylops Spencii emerging from the abdomen of 
bee and various insects, mounted without pressure. 
Mr. Frederick Fitch : Eeproductive organs of the wasp. 
Eev. T. W. Freckelton : New arrangement for attaching the 
polariscope and analyzer to the microscope, so that both can be put 
instantaneously out of the field without unscrewing. 
Mr. A. de Souza Guimaraens : Sections of pearls in different stages 
of development. 
Mr. A. Hilger : A new form of direct vision, very powerful spectro- 
scope, dividing widely D with nickel line between when on sun, with 
micrometer arrangements to measure relative positions to 0 * 0001 to the 
inch. A new micrometer for having two spectra at the same time, or 
even three, and measuring to 0*00020 part of an inch intervals 
between lines. A new pocket spectroscope as devised by the Pre- 
sident, with unusual power for the small size. Diverse eye-pieces, 
with arrangement to measure faint stars. * 
Messrs. How and Co. : Sections of dolerite, &c. 
Mr, Thomas Howse : Crystalloids in albumen of nutmeg. 
Mr. John E. Ingpen : Proposed general standard of magnifying 
power. The microscope is arranged as in ordinary use, and focussed
