At the ordinary meeting held at University College, August 27th, 
1870, Dr. Lionel 8. Beale, F.R.S., President, in the chair, seven new 
members were elected, four gentlemen were proposed for membership, 
a number of donations to the library were announced, and 113 slides 
were presented to the cabinet. A paper was read by Mr. T. C. White 
“On Papers for the Club,” in which he offered a variety of sugges- 
tions as to the kind of papers it was most desired to obtain, and urged 
those members who had hitherto been working at subjects in silence 
to give to their fellow-members the results of their personal experi- 
ences by short practical communications at the meetings. Mr. Curties 
communicated to the meeting an interesting letter received from Mr. 
Davis, describing some remarkable eggs of insects which had been 
found parasitic upon the Black Peacock in the collection of the 
Zoological Society. The subject was illustrated by some very beau- 
tifully-executed drawings, and by a number of photographs presented 
by Mr. Davis for distribution amongst the members. Mr. M.C. Cooke 
exhibited to the meeting a photograph of the appearance of a portion 
of Pleurosigma angulatum, magnified 98,000 diameters, as shown at 
the Bailey Microscopical Club in New York, and of which a descrip- 
tion has been read at the preceding meeting. It appeared, however, 
upon inquiry that the photograph was not taken from the object, but 
from a plaster representation of it. The Secretary read a letter from 
Mr. ©. H. Sterne, of Liverpool, inviting the co-operation of the 
members on the occasion of the Soirée of the British Association to 
* Secretaries of Societies will greatly oblige us by writing their reports legibly 
—especially by printing the technical terms thus: H ydra—and by “underlining ” 
words, such as specific names, which must be printed in italics. They will thus 
secure accuracy and enhance the value of their proceedings.—Ep. M. M. J.
