POPULAR MISCELLANY. 



Edward J. Hallock, A. M., Ph. D.— It is 



with much regret that we have to announce 

 the death, on March 22d, of Dr. Hallock, 

 for many years a contributor to this Jour- 

 nal. He was born in Peekskill, New York, 

 on the 19th of June, 1845. His early edu- 

 cation was in the local schools of his birth- 

 place, ending with the Peekskill Military 

 Academy. In 1865 he entered Columbia 

 College, whence he graduated four years 

 later, receiving the degree of Bachelor of 

 Arts. He was the recipient of the first prize 

 in German, and in 1872 the college also 

 conferred upon him the degree of Master of 

 Arts. Soon after graduating he sailed for 

 Germany, and commenced the study of 

 chemistry in the University of Berlin. In 

 1870 he returned to this country, and was 

 appointed assistant to President Parrish, 

 of Swarthmore College, near Philadelphia. 

 Upon President Parrish's resignation, he 

 too resigned, and, leaving Swarthmore Col- 



lege, was appointed assistant to Professor 

 Joy, occupying the chair of Chemistry in 

 Columbia College. This place he held for 

 several years, acting as professor during 

 Dr, Joy's illness. He went to Germany 

 again in 1877, and was assistant to Pro- 

 fessor Hofmann, in Berlin, and received in 

 1878 the degree of Doctor of Philosophy 

 from the University of Heidelberg. Re- 

 turning then to this country, he was for 

 two years Professor of Chemistry in the 

 Southern Medical College, Atlanta, Georgia. 

 Since 1878 he had been engaged in a large 

 field of scientific work, lecturing in many 

 educational institutions, and acting on the 

 editorial staff of the "Boston Journal of 

 Chemistry " and the " Journal of Applied 

 Chemistry." He was a contributor also to 

 many of the scientific journals of this city. 

 Two laborious chemical indices are his work : 

 one an " Index to the Literature of Titani- 

 um," the other an " Index to the Literature 

 of Glucose," the latter prepared, at the re- 

 quest of Dr. C. F. Chandler, for the Na- 

 tional Academy of Sciences. Both of these 

 have been published, the latter appearing 

 only a short time before his death. His 

 last piece of literary work was a sketch of 

 his German master in chemistry, Dr. Hof- 

 mann, which appeared in the April " Popu- 

 lar Science Monthl}'." 



Dr. Hallock was a man of simple man- 

 ners, modest to a fault, and with great sin- 

 cerity and uprightness of character. He 

 carried this trait into all his work. He was 

 an excellent scientific teacher, and aimed at 

 thoroughness as the first object of instruc- 

 tion. He lectured before many popular 

 schools, and his patience was greatly tried 

 by the tendency he constantly encountered 

 on the part of their managers to make the 

 lectures showy and sensational, so as to 

 captivate ignorant patrons and advertise 

 the institution. 



On the Snpposed Discovery of Iron in 

 Prehistoric Monnds. — It has been generally 

 understood that an iron or steel sword was 

 found many years ago by Dr. Hildreth in 

 one of the prehistoric mounds at Marietta, 

 Ohio, and that an iron blade and a plate 

 of cast-iron were found by Mr. Atwater in a 

 mound at Circlcville ; and these supposed 

 facts have been used to maintain the sup-
