108 SCIENTIFIC SURVEY OF ABERDEEN AND DISTRICT 
CHEMISTRY. 
Brown, Prof. J. CampBeLL.—The son of an auctioneer in Aberdeen, 
and, after graduation, assistant to the Professor of Chemistry in Marischal 
College, 1864, Brown went to Liverpool School of Medicine as lecturer 
on Experimental Science and Toxicology. He was one of the foremost 
spirits in promoting the scheme for a University College in Liverpool. 
When this was accomplished he was appointed to the chair of Chemistry 
in the new college. He was an authority on the latent heat of vaporisation 
of liquids. 
MacxkalLe, MatrHew.—This was a very early apothecary in Aberdeen. 
He was also a writer of books of some quality. His earliest known work 
is The Diversitie of Salts and Spirits maintained, published in Aberdeen, 
1683. For the printing of this book, John Forbes, the Town’s Printer, 
was reprimanded by the Town Council in respect that the work reflected 
on other physicians and chirurgeons in the burgh. 
GEOLOGY. 
CRUICKSHANK, ALEXANDER.—The accomplishments of this man, 
although he was deformed and paralysed from birth, were little short 
of marvellous. He was the son of Prof. Cruickshank, of the chair of 
Mathematics in Marischal College and University. Having graduated 
with ‘ honourable distinction ’ at the University in 1840—bracketed equal 
with Alexander Bain, afterwards Professor, and Rector of the University— 
he devoted himself to study, geology and meteorology taking first place 
in his cultured interest. He was made LL.D. in 1882. 
Lonemuir, Rev. JoHN.—This many-sided man, an accomplished 
geologist, did his most important work in lexicography. In revising 
Jamieson’s Scottish Dictionary he produced a work that was more 
valuable than the original, and corrected Jamieson on the sources of the 
dialect speech of Scotland in a fundamental sense. He was an LL.D. of 
King’s College, 1859, and was one of the Secretaries of the Geology 
Section of the British Association in connection with the visit of the 
Association to Aberdeen in 1859. 
Miter, HucH.—It does not appear that Hugh Miller ever actually 
visited Aberdeen, although on two occasions he passed it on his way to 
Leith by the ‘ smack,’ but his celebrity attaches rather to the whole north 
of Scotland. He was in contact with Prof. Fleming, the geologist, of 
Aberdeen, and doubtless owed something to the association. ‘The bust 
in the National Portrait Gallery, Edinburgh, is by William Brodie, an 
Aberdeen sculptor. 
MirTcHELL, James, LL.D.—He was a graduate of King’s College and 
University, Aberdeen, and in London wrote much on the sciences, 
including geology. His most remarkable production was the compilation 
The Scotsman’s Library, 1825, a singular collection of out-of-the-way 
facts, all carefully indexed. 
NicoL, Prof. James.—Nicol, a Peebles-shire man, was Assistant 
Secretary to the Geological Society, London, 1847 to 1849, when he went
