The salaries of professors in Oberlin Col- 

 lege have been increased $200 each, and the 

 salaries of associate professors $300 each, 

 these increases to go into effect at the begin- 

 ning of the next college year. 



All of the qualified men in this year's 

 graduating class in the College of Agricul- 

 ture of the University of Wisconsin have se- 

 cured positions and the requests for teachers 

 are still coming in. The demand is espe- 

 cially strong from agricultural high schools 

 both in Wisconsin and other states. Many 

 of the requests are for men who have been 

 brought up on farms, have had some teaching 

 experience and also have had a thorough 

 course in agriculture. The demand for such 

 • instructors in agriculture for high schools is 

 very much greater than the supply. Even as 

 early as four vs^eeks ago most of the seniors 

 had accepted positions as farm managers, as 

 research assistants, or as teachers of agricul- 

 ture in colleges and secondary schools. The 

 average salary of the men vcho will teach 

 next year in agricultural schools is $1,253. 



Professor G. A. Bliss, of the University of 

 Chicago, and Professor Max Mason, of the 

 University of Wisconsin, have been appointed 

 lecturers in mathematics at Harvard Univer- 

 sity, the former for the first, and the latter 

 for the second half of the academic year. 



Dr. Stewart Paton '86, has been appointed 

 lecturer in biology at Princeton University. 



Dr. George S. Moler, has been promoted to 

 a fuU professorship of physics at Cornell 

 University. 



E. C. MuLLENix, Ph.D. (Harvard), pro- 

 fessor of biology in Yankton College, South 

 Dakota, has been elected to a similar position 

 in Lawrence College, at Appleton, Wis. 



The following instructors have been ap- 

 pointed at Princeton University: in the de- 

 partment of physics, C. J. Davisson and P. 

 Eosenberg; in the department of electrical 

 engineering, George Olshaussen, Ph.D.; in 

 the department of biology, E. Newton Harvey, 

 instructor in physiology; in the department 

 of civil engineering, P. E. Eickford '11 and 

 -A. C. Cornish '11, instructors in civil engi- 



neering; J. H. Drummond '11, instructor in 



In the Harvard Medical School instructors 

 have been appointed as follows: Dr. Marshal 

 Fabyan, in comparative pathology; Dr. F. P. 

 Johnson, in histology and embryology; Dr. L. 

 B. Nice, in physiology, and Dr. C. G. Page, 

 in bacteriology. 



DISCUSSION AND COEBESPONDENCE 



CONCERNING THE " NEMATOCYSTS OF 

 MICROSTOMA " 



Professor Kepner in a preliminary com- 

 munication entitled " Nematocysts of Micro- 

 stoma " ' brings forward additional evidence 

 showing that nettle capsules capable of sub- 

 sequent discharge may be transferred from 

 coelenterates to flatworms much as they are 

 from hydroids and actinians to eolids. The 

 mechanism of this interesting and suggestive 

 process is described in some detail, but it is 

 hoped that this will be added to and clarified 

 when certain proposed experiments have been 

 carried out. Quite apart from its subject- 

 matter, however, Professor Kepner's paper has 

 an interest especially in the light of Dr. Mc- 

 Dermott's recent " Plea for the Use of Eefer- 

 ences and Accuracy Therein." ' 



Thus on page 271, almost seven lines are 

 quoted and attributed to Boulenger, pp. 127-8. 

 Not only are there no such pages in Bou- 

 lenger's article,^ but the words are taken from 

 my own paper.* 



In the next paragraph Professor Kepner 

 states that the cuidophages of aeolids deliver 

 their nematocysts to the cnidocyst, whereas 

 the endodermal cells of Microstoma deliver 

 their nematocysts to the mesoderm. Unfor- 

 tunately for the analogy, both Grosvenor" and 

 P have shown that the cnidophages after en-
