new members were elected, and ten gentlemen were proposed for

the foreign correspondents of the club, a number of valuable photo- 
micrographs had been received from the Surgeon-General of the 
Army Medical Department at Washington, to whom a unanimous vote 
of thanks was passed. 
A paper was read by Mr. James Jordan, " On the Preparation of 
Eock Sections for Microscopical Examination," in the course of which 
he described a new form of machine for the purpose, having a 2-feet 
driving-wheel and a slitting-plate of soft iron, charged on the edge 
with diamond powder. Provision was made for regulating the thickness 
of the slice and varying the pressure, whilst the polishing was per- 
formed upon a leaden lap similarly mounted. The construction of 
the apparatus was explained by the aid of diagrams ; and a number 
of specimens of rock sections in various stages of preparation were 
placed upon the table for examination. After a few remarks by the 
President, a discussion took place, in which Messrs. Breese, Slade, 
Curteis, and the author of the paj)er took part. Mr. M. C. Cooke 
then read a paper " On Bunt Spores," describing their general charac- 
teristics and variations, briefly reviewing the different observations 
made upon them since 1848, and critically examining the evidence as 
to their supposed connection with the cholera epidemic. The paper
