abroad and studied through the summer semester at Hreslau with 

 Professor A. von Lasaulx, devoting himself' especially to micro- 

 scopic lithology. On reluming to New Haven he resumed In- 

 former position as instructor, and retained it until the following 

 spring, when he again went abroad tor further study. From 

 March 1879 to June 1880, he was a student of mineralogy and 

 crystallography at Bonn with Professor vom Rath, and of lithol- 

 «.'iv at Heidelberg with Professor Rosenbusch. At the comple- 

 tion of his studies in Heidelberg he took there the degree of 

 Doctor of Philosophy. He returned once more to his old place 

 and duties in New Haven. But at the end of the year (1880) he 

 accepted the position of Director of the theological Department of 

 the National Museum at Washington, which he held up to the 

 time of his death. During the first half of the year of 18S1, Mr. 

 Hawes, besides carrying on his labors in connection with the 

 Museum, was engaged on a special study of the building stones of 

 the country, undertaken under the an-pices of the U. S. Census. 

 His interest in this work led him to overtax his strength, and 

 before the close of the year it became evident to his friends that 

 consumption had taken a strong hold of him; -and in some nine 

 months after the disease was first distinctly recognized, it had 

 done its work. 



The death of Dr. Hawes takes from the ranks of the younger 

 scientific workers in the country one of the most gifted and prom- 

 ising. 15y years of patient study, urged forward by his own love 



cnces from outside, he had fitted himself to 

 in the subjects to which he had devoted 



i for the deepest regret that so useful a lite 

 should be cut off thus prematurely. During the years of his resi- 

 dence in New Haven, Dr. Hawes*puhlished sonic't went\ memoir* 

 on various subjects connected wilh mineralogy and lithology. 

 In 1878 he wrote a report on the mineralogy and lithologv of New 

 . published as Part iv of the Geology of New Hamp- 

 shire. This report covered 2ol pages (4to) with twelve plate-, 

 and forms his most impoi nIl ,,-j'i,,; i o science : it contain- 



the results of extensive held work, as well as the microscopic ex- 

 amination ,.f several hundred thin sections of rocks. It is through-

 gation of the building stones of the country, already alluded to, 

 was a work in which he felt great interest* and which promised 

 to yield most valuable results; unfortunately he was not allowed
