202 THE AMERICAN MONTHLY [September, 



Friday Morning. 



A number of business propositions were considered. A resolution 

 was adopted calling on Congress to remove or reduce the duties now 

 levied on foreign microscopical apparatus, as altogether higher than 

 necessary for the protection of the American makers. 



The treasurer's report was read, showing $276 on hand at the open- 

 ing of the meeting. 



The election of officers followed, and the names proposed by the 

 nominating committee were unanimously elected. 



The question of the new constitution and change of name was then 

 discussed. It was decided that in the future the society should be known 

 as the American Microscopical Society, instead of the American Society 

 of Microscopists. Considerable discussion followed as to the steps 

 necessary to carry out the transfer of property and membership from 

 the old to the new society. The details having been satisfactorily ar- 

 ranged, the reading of papers was continued. 



Dr. J. M. vStedman read two very interesting papers, the first on 

 " Killing of Invertebrata in an expanded condition," and the second 

 '•'■ On the nervous system of a fresh-water sponge." 



The following papers were presented to the committee, but owing to 

 the great amount of time devoted to visiting the Government Depart- 

 ments, as well as to the absence of several of the authors, they were 

 mostly read by titles only. 



By Prof. M. D. Ewell : "A new form of graphological microscope," 

 and " Standard glass and speculum metal centimetres." 



By Prof. W. A. Rogers: "The relations between a mikron and a 

 wave length of sodium light." 



By Dr. Wm. C. Krauss : " The microscope as a factor in the diag- 

 nosis, prognosis, and treatment of morbid new growths." 



By Dr. Veranus A. Moore: "Apparatus for holding cover-glasses 

 when staining." 



By Miss V. A. Latham : " The use of stains, especially with refer- 

 ence to their value for differential diagnosis." 



By Dr. Lucien Howe: "Floating particles in the eye a source of 

 error in microscopical observation," and " The mecli^nical stage used 

 as a micrometer." 



By Prof. Simon H. Gage : " Notes on the fixation of serial sections 

 and the collodion method in histology," and " Preparation of the fibrin 

 filaments of blood and lymph, and of the oxyhsemoglobin crystals of 

 Necturus." 



By Prof. John Michels : " The microscopical examination of pork 

 by the U. S. Government." 



At the conclusion of the morning sesssion, the society was declared 

 adjourned sine die^ after having spent one of the most enjoyable meet- 

 ings ever held. The time and place for next year's meeting will be de- 

 termined by the Executive Committee and hereafter announced.

 Fine exhibits of microscopes, objectives, accessories, microtomes, 

 mounting instruments and materials, lenses of all descriptions, cabinets 

 for slides, microscopical literature, and mounted objects were made by 

 the following well-known dealers in microscopic supplies :
