694 THE POPULAR SCIENCE MONTHLY. 



science has recently written of Prof. Lovering's articles that they 

 impressed him as few others had ever done. " It will surprise him 

 to know it ; yet it is true that the ideas then presented, and with 

 an elegance worthy of their breadth and power, affected the whole 

 tenor and tendency of my thoughts, and thus of my subsequent 

 life. At this moment I could repeat by memory long passages 

 from these articles. They were upon ' The Internal Equilibrium 

 of Bodies/ ' The Application of Mathematical Analysis to Physical 

 Research,' ' The Divisibility of Matter/ etc." And he compares 

 the style of parts of them with that of the most classic passages 

 in Babbage's " Ninth Bridgewater Treatise." 



Mr. R. W. Emerson published the following notice for the 

 " Dial " : * " We rejoice in the appearance of the first number of 

 this quarterly journal edited by Prof. Peirce. Into its mathe- 

 matics we have not ventured ; but the chapters on astronomy and 

 physics we read with great advantage and refreshment. Espe- 

 cially we thank Prof. Lovering for the beautiful essay on the 

 ' Internal Equilibrium and Motion of Bodies/ which is the most 

 agreeable contribution to scientific literature which has fallen 

 under our eye since Sir Charles Bell's book on the hand, and 

 brings to mind the clear, transparent writings of Davy and Play- 

 fair. Surely this was not written to be read in a corner, and we 

 anticipate the best success for this new journal." 



Prof. Lovering is a member of the American Academy of Arts 

 and Sciences in Boston ; was its corresponding secretary for many 

 years ; was afterward its vice-president, and its president since 1880. 

 He is also a member of the National Academy of Sciences, of the 

 American Historical Society of Philadelphia, of the California 

 Academy of Sciences, and of the Buffalo Historical Society. In 

 connection with the work of the United States Coast Survey from 

 1867 to 1876, he had charge of the computations for determining 

 differences of longitude in the United States and across the 

 Atlantic Ocean, by means of the land and cable lines of telegraph. 

 He was for some years one of the trustees of the Tyndall fund for 

 the endowment of scientific research, and is now one of the 

 trustees of the Peabody Museum of Archseology and Ethnology. 

 Besides the papers already mentioned, Prof. Lovering contributed 

 other articles to the " Memoirs " and " Proceedings " of the Ameri- 

 can Academy, and scientific articles and reviews to the " Proceed- 

 ings of the American Association," the "American Journal of 

 Science," the " Journal of the Franklin Institute," the " American 

 Almanac," the "North American Review," the "Christian Ex- 

 aminer," " Old and New," and " The Popular Science Monthly."
