SCIENCE. 



[N. S. Vol. IV. No. 84. 



cided on July 28th that the State Legislature 

 has no right to interfere with or dictate the 

 management of the University of Michigan. 

 The Legislature passed an act at its last session 

 directing the regents to establish the homeo- 

 pathic department of the University in Detroit. 

 The regents refused to comply on the ground 

 that the act was unconstitutional, and a man- 

 damus was asked for to compel them to estab- 

 lish the department in Detroit. The Court 

 holds that the regents have the sole control of 

 the University and that the act of the Legisla- 

 ture is invalid. 



Ground has been broken for the new science 

 hall at Lake Erie Seminary, O. Of the $20,000 

 required for the completion of the building, 

 $14,000 has already been raised. In addition 

 $10,000. has been subscribed for equipment. 



Dr. H. T. Lukens, of Clark University, has 

 been appointed professor of education at Bryn 

 Mawr College, and Dr. Colin A. Scott to the 

 chair of experimental psychology and child 

 study at the Chicago Normal School. 



Mr. Ben F. Hill, B. S. , has been appointed 

 Fellow in Geology at the University of Texas. 

 He will assist in the laboratory instruction in 

 paleontology and mineralogy under the direc- 

 tion of Dr. F. W. Simonds. 



Mrs. Arthur Jackson has contributed to 

 the Sheffield Medical School the sum of £5,000 

 towards the endowment of a chair of anatomy, 

 to be called the Arthur Jackson Chair of Anat- 

 omy. Mr. Jackson, who died recently, was 

 much interested in the success of the Medical 

 School, and had served it in the capacity of 

 Secretary and Lecturer. 



Dr. J. Norman Collie, F.E.S., has been ap- 

 pointed professor of chemistry in the Pharma- 

 ceutical Society's School of Pharmacy. Dr. 

 Collie has been for some time associated with 

 Professor Ramsay in the teaching of chemistry 

 at University College, London. The Council of 

 Bedford College for Women, London, has ap- 

 pointed Dr. Thomas Morison Legge, to the pro- 

 fessorship of hygiene.

DISCUSSION AND CORRESPONDENCE. 

 the personal equation. 

 In the admirable heliometric triangulation of 

 the cluster in Coma Berenices, by Dr. F. L. 

 Chase, lately published by the Yale Observatory, 

 the author has not noticed that the cluster is 

 one which was photographed by Mr. Ruther- 

 furd in 1870 and several years since ; hence, 

 material is already on record for the proper mo- 

 tions of the group. The cluster will furnish an 

 unusual number of stars which can be observed 

 for personal equation between bright and faint 

 ones, a problem which is not without psycho- 

 logical as well as astronomical interest at the 

 present time. It will be remembered that 

 among very eai-ly studies in experimental psy- 

 chology were those experiments conducted by
