but the Hon. Secretary, by whom they will be retained for future 

 reference, or published if deemed expedient, by the Committee. 

 Drawing-paper of suitable quality and size can be obtained on 

 application to the Hon. Secretary. 



It has been arranged to circulate several special series of 

 slides. One devoted to Histological and Pathological subjects will 

 circulate among the whole of the medical members, and will also 

 be sent to all other members who desire to see them, if they will 

 communicate their wish to the Hon. Secretary. Other series con- 

 sisting of Diatomacese, Fungi and general Botanical slides, 

 Foraminifera, and slides illustrating various other branches of 

 Natural History are in circulation; these are sent through the 

 entire circuit of the Society. 



All members are invited to contribute a series of six or twelve 

 slides to these special sections, but it must be distinctly understood 

 that they are required, before doing so, to contribute their qiwta of 

 slides to the regular boxes of the Society. Every slide, in each 

 case, must be accompanied by descriptive notes, and should also 

 be illustrated by a drawing. 



Each member on admission to the Society is requested to 

 send his Carte-de-vis ite to the Hon. Secretary, and as soon as 

 sufficient portraits are collected, they will be grouped together and 

 reproduced, and as this is for promoting a friendly feeling towards 

 one another, each member, it is hoped, will take a copy of the 

 same when published. Two of these groups have now been 

 published : the first, which consists of sixty-four portraits, was 

 printed in 1874, in Permanent Photography, by the Autotype Fine 

 Art Co. The other, in which the portraits are arranged in a more 

 pleasing manner, was printed in 1878 also in Permanent Photo- 

 graphy by the Woodbury Permanent Photographic Printing Co. 

 The two form very nice companion pictures. They are published 

 by the Hon. Secretary. Several copies of the second group 

 remain on hand, and may be had from him at 8/6 each, post free. 



The President, at the termination of his year of office, will, if 

 he deems it desirable, give a short address or written summary, 

 recounting the proceedings of the Society, and the President-Elect, 

 on taking the chair, will also read a paper referring to such Natural 

 History and Microscopical subjects as he may deem conducive to 

 the welfare and the furtherance of the objects of the Society. 



Several gentlemen have presented a number of valuable slides 

 to the Society. These will be kept by the Hon. Secretary for the us 

 of the members, and will form the Reference Cabinet.
