who also made the excellent drawings of the different phases 
of the comet as shown on the accompanying plates. 
In the later years of his service at the Observatory he pre¬ 
pared for each annual report of the Smithsonian Institution 
a paper on the “ Progress of Astronomy,” giving, in consid¬ 
erable detail, an account of the work of the principal obser¬ 
vatories, a list of the discoveries, a brief resume of the more 
important astronomical publications, together with a com¬ 
plete astronomical bibliography for the year. This interest¬ 
ing and valuable work was continued from 1885 to 1892. 
In 1886 he was appointed Professor of Astronomy in the 
Corcoran Scientific School of the Columbian University, 
meeting his classes principally in the evening, and at the 
time of his death he held the same position, together with a 
similar professorship in the Graduate School of the same 
University. 
As the years of exacting work passed by, Mr. Winlock 
lost no interest in astronomical pursuits, which he had early 
chosen to follow, but he began to realize that the chances for 
promotion or increase of pay at the Observatory were almost 
infinitesimal, and that such advantages must be sought in 
other directions. Accordingly, when the Secretary of the 
Smithsonian Institution offered him the office left vacant by 
the death of Dr. J. H. Kidder, he felt that duty to himself 
and to his family impelled him to accept the position, ar¬ 
dently hoping that he might in his new field find an oppor¬ 
tunity to devote a portion of his time to some branch of 
astronomical investigation. 
On May 14, 1889, he was appointed “ Curator of Inter¬ 
national Exchanges” in the Smithsonian Institution. In 
1891 his sphere of work was enlarged by assignment as 
“ Assistant in charge of Office,” and still later he was made 
“ Curator of Physical Apparatus ” in the U. S. National 
Museum. In this new field of activity his innate liking 
for scientific work was held in abeyance by the pressure 
of administrative business, and by his dominant desire to 
see that every duty was faithfully performed. His buoy-
