170 THE AMERICAN MONTHLY [May 



made in any branch of microscopical work, always receive 

 a courteous hearing- from the society, and frequently valu- 

 able assistance is afforded by hints from the ripe experi- 

 ences of the Fellows. The Journal, which is issued bi- 

 monthly to the members, contains, in addition to the trans- 

 actions, a summary of current researches in zoology, 

 botany and microscopy throughout the world, and is an in- 

 valuable record for workers. The extensive library and 

 instruments are always at the disposal of members, and 

 the rooms at 20, Hanover Square, are open daily. 



Representing, as it does, microscopy in its scientific as- 

 pect only, the membership is necessarily limited, and the 

 very high standing of the society has rather tended to dis- 

 courage workers from applying for admission to its ranks, 

 but all really interested microscopists are entitled to claim 

 its advantages by becoming Fellows. The "toy" micro- 

 scopist, who uses — or rather misuses — his instrument for 

 curiositv and amusement, is not eligible, but any person 

 who may be desirous of gaining a better understanding 

 of the theory and methods of employment of the most fas- 

 cinating instrument ever devised, or wishes to be au fait in 

 eurrent scientific microscopy, will have no difficulty in find- 

 ins - a Fellow who will nominate him. The secretaries of 

 the society are always glad to render assistance to such 

 persons. The society should have on its roll every earn- 

 est worker, and it is the duty of such to afford his best 

 support to the society, not alone for his individual benefit, 

 but for the good of microscopy generally and the vast in- 

 terests that are interwoven with it.
