illustrious, and, in many i-espects, wonderful progeny, which occurs 

 next year. The local microscopical society of Pittsburg is one of 

 the most active and thriving organizations of the kind in the 

 country, and the warm invitation given the A. S. M. will certainly 

 be followed by a still warmer and most gracious reception, so that 

 even at this date, we have no hesitation in prophesying that the 

 coming meeting will be one of the most enjoyable and successful 

 yet held. It might be objected by some that the meeting of last 

 year having been held in the East, the coming gathering should be 

 in this direction. To this may be answered that more meetings 

 have been held West than East, and especially is the place well chosen, 

 on account of the congress referred to, which every medical member 

 of the A. S. M. will desire to attend, in connection with the micro- 

 scopical meetings. The growing importance of our society is, we 

 believe, recognized by all ; but, although much has already been 

 done, there remains more to be accomplished. "We hope, therefore, 

 that every member will so arrange his or her summer vacation as 

 to take in Pittsburg August 30, when the meeting will be held. We 

 trust, too, that every worker with the microscope will come prepared 

 to make the meeting a success, and, by paper, work or exhibit, add 

 what they can to the general interest, and to the advancement of 

 the A. S. M. Pittsburg, August 30, 1887. 



We should be very glad if the I'eaders of The Microscope would 

 send us practical points in regard to the treatment of microscopical 

 objects. Short, concise notes on preparing, preserving, hardening, 

 embedding, cutting, staining and mounting objects — new instruments 

 and methods of work are always acceptable. Five lines on practical 

 work ar© often of more help to the worker and amateur than pages 

 of description. As we have all stages in microscopical development 

 represented among our readers, from the expert to the dilettante and 

 tyro, we desire to furnish matter of interest to both, and both will 

 always find in our pages something which will be of service in his or 

 her particular stage of development. Let every reader of these lines 

 adopt the motto of the Prince of Wales, " Ich dien," (I serve) and 

 endeavor, by sending us notes or articles which may be of help to 

 others, to assist in disseminating the science of which this magazine 

 is an exponent. There is altogether too much selfishness in this world, 

 and many a man lives and dies with his knowledge hidden in his own 

 brain, of use to himself perhaps, for a time, but of no benefit to the 

 world. Let this be said of no microscopist. Certainly the wonde r-
