Island Exploring Expedition. He contributed a series of 
papers on the results of these expeditions to the American 
Journal of Science and other magazines. On another occa- 
sion he revisited Greenland—this time in the company of 
Edward Whymper—and subsequently wrote several other 
papers bearing more or less upon glacial physics. 
After his return from this latter expedition, he was 
appointed Lecturer on Geology, Zoology, and Botany at 
the Watt Institution, Edinburgh, and at the Mechanics 
Institute, Glasgow. 
He took a prominent part in the management of the 
Edinburgh Field Naturalists’ Club, and was appointed the 
first President of that body. In 1872 he was elected 
President of the Royal Physical Society, and subsequently 
fulfilled the duties of Secretary to the same Society during 
the years 1874-76. 
Amongst his published works are some few on Natural 
Science subjects contributed to our Proceedings. He is 
better known, however, amongst geologists in general, in 
connection with his paper “On the Physical Structure of 
Greenland,” published in the papers for the Arctic Expedi- 
tion of 1875, as well as for others on kindred subjects which 
appeared in the Quarterly Journal of the Geologie Society 
of London and elsewhere. 
In addition to his original contributions to scientific 
literature, Dr Brown was the author of a large number of 
compilations, most of them dealing in a popular manner 
with various branches of Natural Science. 
Of late years he had devoted himself mainly to purely 
journalistic work in connection with the Scotsman, the Lcho, 
the Standard, and others. 
He died at Streatham on the 26th of October 1895.
