326 Scientific Intelligence. 
sor Henry, extending as they did over more than half a century, 
played so important a part in the development of science in this 
country that it is well, alike for the reputation of their author as 
for the interests of the worker of to-day in the same fields, that 
they should be collected and given to the world in convenient 
form. This is especially true in view of the fact that the original 
papers were much scattered and many of them are now hardly 
accessible. The collection is published by the Institution of which 
he was Director for more than thirty years, and to which he devoted 
a large part of his life’s energies. The first volume contains the 
greater part of the papers on physical subjects, extending from 
1824 to 1855, with also the acoustical researches of 1874 to 1877. 
The second volume is largely occupied with the more popular 
Meteorological Essays, with also papers on some other kindred 
subjects ; the volume closes with the addresses to the National 
Academy of Sciences in April, 1878. The life of Professor Henry 
was conspicuously active and productive, and his original con- 
tributions to Physical Science, particularly in the branch of elec- 
tro-magnetism, have given him a place he will always hold in the 
foremost rank of American workers. 
2. The American Naturalist—The American Naturalist will 
be in future published by the house of J. B. Lippincott & Co. of” 
Philadelphia, under a slight change of editorial management. 
Dr. Packard retires, and Dr. J. S. Kingsley becomes with Profes- 
sor Cope assistant editor-in-chief. The remainder of the editorial 
corps continues as before, excepting the addition of Professor J. 
H. Comstock of Cornell University, who will have charge of the 
Entomological Department. As stated on its title-page it is “A 
Monthly Journal devoted to the Natural Sciences in their widest 
sense,” and, we add, value to all interested in its departments. 
3. Van Nostrand’s Science Series.—Recent issues of this series 
are No. 90, Analysis of Rotary Motion as applied to the Gyro- 
scope by Major J. G. Barnard, a reprint of the well-known paper 
first published in 1858 in the Journal of Education. Also, No. 
91, Leveling, barometric, trigonometric and spirit by Ira O. Baker; 
this gives a clear and simple statement of the methods applied 
to the determination of altitudes. 
OBITUARY. 
Joun Artuur Puitiies, F.R.S.—Mr. Phillips, the distinguished 
author of works on Ores, Mining and Metallurgy and of papers 
on petrography, died on the 5th of January, in his 60th year. 
He was engaged, at the time of his death, on a new edition of his 
work on “ Metallurgy,” in conjunction with Mr. Bauerman. In 
connection with his study of gold deposits he visited the gold 
regions of California in 1861 when he made observations of much 
interest on the formation of veins. ‘“ Nature,” of January 138th, 
closes a notice of Mr. Phillips with the words: “‘ He was a large- 
hearted and open-handed man, fond of taking every chance that 
came in his way of doing a good deed and helping any one to 
whom his help could be of service.”
