HON. SECRETARY: 



ALFRED ALLEN, 1 Cambridge Place, Bath, Eng. 



The Society was formed in 1873 to aid in 

 the study, discussion and circulation of Mi- 

 croscopic objects, and to advance the pursuit 

 of Natural Science among its members. 



It is divided into Circuits of about twelve 

 members each, arranged geographically. A 

 box of Slides accompanied by MS. book for 

 the insertion of Notes and Memoranda, is 

 sent by the Hon. Secretary, at fortnightly 

 intervals, to the first member on one of the 

 Circuits; who, after keeping it for three 

 days, must send it on by post to the next on 

 the list, and he to the following one. When 

 it has gone round the Circuit the last mem- 

 ber returns it to the Hon. Secretary, who 

 will then forward it to the first member of 

 the next Circuit, and so on, until the Slides 

 have been seen by the whole of the Society. 

 Each member is expected to contribute six 

 Slides annually, which are returned to him 

 after they have been around the Circuits. 

 Ladies, as well as gentlemen, may be elected 

 members of the Society. 



All communications on matters connected 

 with the Society should be addressed to Mr. 

 Alfred Allen, as above.
