168 Scientific Intelligence. 



In all these years of scientific observational activity, with the 

 pressure of University duties ever upon him, and in later years 

 with impaired health, he yet found time to publish many articles 

 in periodicals both scientific and popular, delivered popular 

 lectures at the Peabody Institute, Baltimore, and Lowell Insti- 

 tute, Boston, and educational courses for successive years at 

 Mount Holyoke College, Williams College, St. Paul's School and 

 elsewhere. He wrote several books. " The Sun," a volume in 

 the International Science Series, 1882 ; "General Astronomy for 

 Colleges and Scientific Schools," 1889; "Elements of Astron- 

 omy," 1890; "Lessons in Astronomy," 1891; and "Manual of 

 Astronomy," 1902. 



Such a life of scientific achievement did not go without public 

 recognition. He received the degree of Ph.D. from Pennsylvania 

 1870 and Hamilton 1871, and that of LL.D. from Wesleyan 

 1876, Columbia 1887, Western Reserve 1893, Dartmouth 1903 

 and Princeton 1905. He was a member of the National 

 Academy of Sciences, and a Foreign Associate of the Royal 

 Astronomical Society of England ; member Astron. and Phys. 

 Soc, vice pres. 1902 ; fellow A. A. A. S., vice pres. 1876, pres. 

 1883 ; Assoc, fellow Amer. Acad. Arts and Sci., Boston ; Hono- 

 rary member of N. Y. Acad. Sci., Philadelphia Philos. Soc, Brit. 

 Assoc, Cambridge Philos. Soc, Manchester Lit. & Philos. Soc, 

 Astron. G^sell., Sdc Ital. di Spettroscop., and President of the 

 Board of Visitors of U. S. Naval Observatory 1901-2. 



Before closing this brief notice of Prof. Young's life, some 

 mention of his personal character as a friend and a Christian 

 must not be omitted. During the twenty-eight years of his life 

 at Princeton the writer was associated with him in the University 

 work and can testify to his estimable qualities as a Christian 

 man of science, never losing sight of "the God behind the Nature 

 which he loved and studied. The resolutions of the University 

 Faculty well say : " His transparent honesty, his unaffected 

 modesty, his insight into principle, and his achievement in dis- 

 covery united to give his career not only distinction but also 

 grace and beauty, and his qualities as a man won for him our 

 love as well as our admiration," while the students' paper speaks 

 of his "lovable, mauly Christian character." So all who knew 

 him mourn his loss, while recognizing the beaut}'' of his life.

Pierre Jules Caesar Jaxssex, the eminent French astron- 

 omer and director of the Observatory atMeudon, died on Decem- 

 ber 23 at the age of eighty-three years. His scientific labors 

 extended into various fields ; he was one of the first to use the 

 spectroscope in the study of the sun and accomplished important 

 results at the transit of Venus in 1874, and at a number of solar 

 eelipses, particularly those of 1868, 1870, and 1883 ; even in 1905, 

 when a man of eighty, he was an active observer. 



Dr. Peter Townsend Austix, at one time Professor of Chem- 

 istry in Rutgers College, later a consulting chemist, died on 

 December 30 at the age of fifty-four years.
