If we consider that it is a mesencephalic segmental nerve, the anomaly would be 

 imperfectly atavistic. If it belongs to the post-mesencephalic segment, the 

 nucleus of origin must have been displaced forwards. If the second primary 

 cerebral incisure has no real segmental value, the nerve would be within the 

 Umits of a single segment, and the anomaly would have no significance.

NEWS AND NOTES. 



A Brvological Memorial Meeting at Columbus, Ohio. — Columbus 

 was the home for many years of William S. Sullivant and Leo Lesquereux, two 

 names which will always awaken love and reverence from all students of North 

 American mosses and hepatics. It is twenty-six years since Sullivant died, and 

 this last quarter of the century has seen a marked extension of the limits of 

 bryological study and a large increase in the number of students. It seems a 

 fitting time and place to take a survey of the field, review the past, and make 

 plans for the future ; hence it is proposed to make the coming meeting of the 

 American Association for the Advancement of Science, which is to be held at 

 Columbus, the occasion for a Memorial day in honor of the Nestors of American 

 bryology, and to call on all botanists and scientific magazines to help make the 

 occasion a memorable success. It is proposed to present a series of papers 

 illustrated by specimens, photographs, microscopical slides, as well as by books 

 and pamphlets, and to show the work of Hedwig, Palisot de Beauvois, Michaux, 

 Muhlenberg, Eridel, Torrey, Drummond, Hooker and Wilson, Greville, Sullivant 

 and Lesquereux, James and Watson, Austin, Ravenel and Garber, Rau and 

 WoUe, Brandegee, Eaton and Faxon, Miiller and Gottsche. Supplementing 

 these, there will be shown collections of specimens macroscopic, and micro- 

 scopic, illustrating the monographic work of living American students. 

 Foreign students who have worked on North American mosses will be 

 asked to cooperate with us. An effort will be made to secure the loan 

 of type specimens and illustrations from the various public and private 

 herbaria and libraries, both here and abroad, as well as from private 

 collections. It is also intended to exhibit any portraits, autograph letters, type 

 specimens and drawings of special interest which may be loaned for the occasion, 

 as well as presentation copies of books and pamphlets. The following com- 

 mittee of organization will gladly answer questions and give assistance to those 

 wishing to contribute : Mrs. N. L. Britton, New York Botanical Gardens ; Prof. 

 W. A. Kellerman, Ohio State University ; Prof. Charles R. Barnes, University 

 of Chicago ; Dr. George G. Kennedy., Readville, Mass. ; Prof. L. M. Under- 

 wood, Columbia University. 



The coming meeting of the American Microscopical Society at Columbus, 

 O., August 17 to 19, will certainly be one of the best in the history of the society. 

 The practical character and number of the papers already presented to the com- 

 mittee are in keeping with the rapid growth of the use of the microscope in all 

 branches of science. Directors of laboratories, their assistants, medical men, 

 and investigators, will find in this meeting material which is not found else- 

 where, and which is very important to them.
