JANUARY 24th, 1868. 

 Arthur E. Durham, Esq., President, in the Chair. 



The minutes of the previous meeting having been read, the secretary an- 

 nounced the following donations: — "The Naturalist's Circular," from the 

 Editor ; " The Popular Science Eeview," from the Publisher, and the Lord's 

 Prayer, written in the two thousand five-hundredth part of an inch, from 

 Captain St. John. 



The thanks of the meeting were voted to the donors. 



The following gentlemen were proposed for membership:— Mr. Thomas Crook, 

 F.E.M.S., Mr. P. E. Leefe, and Dr. Dempsey, F.E.M.S. 



Ten gentlemen proposed at the previous meeting were then balloted for and 

 duly elected. Dr. Arthur Mead Edwards, of New York, who was proposed 

 at the last meeting as an honorary foreign member, was also duly elected. 



The President stated that the subject of the microscopic investigation of deep 

 sea soundings having been brought before the notice of the committee, one of 

 their number, Mr. Arnold, had communicated with Capt. G. E,, Eichards, 

 E.N., as to the possibility of obtaining his help in the collection of the neces- 

 sary material. Capt. Eichards had expressed his willingness to assist, and with 

 his letter had forwarded a box of specimens. It was proposed to form a com- 

 mittee of gentlemen having some knowledge of the subject, to examine the 

 soundings thus obtained, and the names of gentlemen willing to join were 

 requested to be sent to Mr. Arnold, who had consented to act as secretary of 

 the sub- committee, when formed. 



Mr. M. C. Cooke then read his paper on "The Hairs of Indian Bats" (see 

 page 33), at the conclusion of which, he presented the whole of the slides 

 illustrative of his paper, together with others, amounting to one hundred, to 

 the Cabinet of the Club. He also presented the diagrams used by him, con- 

 taining 43 figures of bats' hair, on an enlarged scale, with the portfolio contain- 

 ing them, to the library of the Club. 



The especial thanks of the meeting were expressed to Mr. Cooke for his valu- 

 able paper, and for the handsome gifts accompanying it. 



Mr. Burgess drew attention to the point that as bats' hair was so much ser- 

 rated it ought to " felt" well, whereas there was no felting property. This 

 fact seemed to coincide with his own deductions in his paper read at the last 

 meeting. 



The President announced that at the next meeting Mr. Hislop would give 

 some suggestions on Oblique Illumination, and Mr. Draper would read a paper 

 • * On the proper application of the Microscope by Amateurs," and the meeting 

 terminated.
