4-4 Journal of Applied Microscopy. 



latest and best apparatus for this work. The building is, in design and general 

 appearance, one of the most attractive on the campus, and is easily accessible 

 from the city hotels. All the facilities of the institution will be placed at the 

 command of the society, which is thus insured the most satisfactory environment 

 for a successful meeting. 



The programme will contain the contributions of some of the most active and 

 inHuential workers in the microscopical sciences, and will compare favorably 

 with the scientific work accomplished at previous meetings. 



A portion of the programme has been arranged especially for teachers of 

 the natural sciences in our grammar and high schools, and, with this end in 

 view. Professors S. H. Gage, and V. A. Moore of Cornell University, Dr. A. C. 

 Mercer of Syracuse, the president, Dr. Wm. C. Krauss of Buffalo, the secretary. 

 Professor H. B. Ward of Lincoln, Neb., and others, will present papers dealing 

 with technique and laboratory methods best suited for high school teachers and 

 private workers. In addition to this, papers embodying the results of the most 

 advanced investigations have been promised by original workers in the several 

 departments of biological science, which will be of value and interest to the 

 more advanced workers with the microscope. 



Thus, with reduced rates, an admirable meeting place, a hearty welcome, an 

 unexcelled programme, both for the elementary and advanced worker, and the 

 cordial support of the officers of the society, the Columbus meeting promises to 

 be one of the best the society has ever held. Every member of the society 

 should, if possible, be in Columbus August 17, IH, and 19, 1899. Titles of 

 papers may be sent to the president or secretary.

American Association for the Advancement of Science. — Columbus, 

 Ohio, where the next meeting of the American Association for the Advancement of 

 Science is to be held, was for many years the home of William S. Sullivant and 

 Leo Lesquereux. It is now more than a quarter of a century since the death of 

 Sullivant, the greatest of American bryologists. It is, therefore, intended to set 

 apart a day for a bryological memorial meeting. The committee which has the 

 matter in charge is planning a series of historical papers presenting the bryolog- 

 ical work of the great masters in this subject, to be illustrated by type specimens, 

 books, presentation copies of phamphlets, autograph letters, etc. European 

 bryologists who have worked upon North American mosses will be asked to con- 

 tribute. We shall hope to publish further details when the plans are further 

 developed. 



When preparing earthworms for sectioning, particles of sand and gravel in the 

 alimentary canal, that might injure the microtome knife when the specimen is 

 cut, may be removed by feeding the worms bits of filter paper before killing. 



In laboratories that do not have running water, a source of supply may be 

 improvised by using any large cask that is fitted with a spigot. The cask may 

 be placed on a stand to raise it to a convenient height, and filled with water as 

 often as required.
