POPULAR MISCELLANY. 



Death of Professor Dana. Prof. James 

 Dwight Dana, the veteran American geologist, 

 died at his home in New Haven, Conn., of 

 disease of the heart, April 14. He had been 

 apparently in good health, manifesting no 

 signs of weakness other than by taking his 

 walks less frequently, but on the morning 

 before his death was attacked with a nerv- 

 ous fluttering of the heart, which, being not 

 uncommon with him, was not regarded as 

 serious. After sleeping for a while at night, 

 he awoke feeling worse, and died before the 

 doctor was able to reach him. A brief sketch 

 of Prof. Dana's life and work up to that time 

 was given in the third number of The Popu- 

 lar Science Monthly, July, 1872. Besides 

 the books and published papers mentioned 

 in that article he has since revised the text- 

 books and manuals of geology and mineralogy, 

 bringing them up to very recent dates ; added 

 to his works The Geological Story Briefly 

 Told and a small volume on the New Haven 

 region entitled The Four Rocks ; contributed 

 numerous papers on scientific subjects to the 

 journals in which they appropriately found a 

 place; and edited the American Journal of 

 Science to the end of his life. He continued 

 to serve in his professorship in Yale College 



till 1892, when he asked the corporation to 

 appoint his successor, and Prof. H. S. Wil- 

 liams was elected ; but he continued, at the 

 request of the corporation, to deliver his 

 lectures till January, 1894. After this he 

 finished the revision of his Manual of Geol- 

 ogy, which has been published recently ; 

 continued his contributions to the American 

 Journal of Science ; kept up his investiga- 

 tion of the phenomena of the Hawaiian vol- 

 canoes, for which he made a recent visit to 

 the Sandwich Islands in 1887; and com- 

 pleted a short work on Cephalization, or a 

 system of classification based upon progress- 

 ive nerve centering in the brain. He was 

 a man of lovable disposition and high per- 

 sonal character; and he held honors, mem- 

 berships, or medals from most of the im- 

 portant scientific societies of the world. 

 The complete list of his books and published 

 papers given in the American Journal of 

 Science contains two hundred and fourteen 

 titles. It begins with a paper on the Condi- 

 tion of Vesuvius in 1834, published in 1835, 

 and ends with the fourth and revised edition 

 of the Manual of Geology, which Prof. Dana 

 finished in February, 1895. A month later 

 he had completed the manuscript of a new 

 edition of The Geological Story, and then be- 

 gan work on a new edition of the Text-Book. 



Treatment of the Morally Defective. 



The question of the treatment proper to be 

 applied to the morally defective was treated 

 with considerable effectiveness by Prof. A. J. 

 McClatchie, in a lecture delivered at Pasa- 

 dena, Cal. The speaker first named the in- 

 fluences under which persons became crim- 

 inals. Many are born of convicts or of 

 criminals who have escaped punishment, 

 and hence have a natural tendency to be 

 morally deranged. Other persons are sur- 

 rounded by unfavorable circumstances, and, 

 being weak, are drawn into a life of crime 

 against their will. Others are quick-tem- 

 pered, irritable, supersensitive, and liable at 

 any time to be provoked to do that which 

 they would not do in soberer moments. 

 Others are born of good parents and have 

 good surroundings, but under certain cir- 

 cumstances such as the influence of bad 

 associates and in their weakness yield 

 gradually to temptation, and thus slowly 

 develop into criminals. Shutting these per-
