MEMOIR OF THE LATE DR THOMAS CHARLES HOPE. 421 
In his way to the French capital, he made a short stay in London, where he 
was very kindly received by Sir JosepH Banxes ; and he had the high gratifica- 
tion of being introduced to CavEeNbisH, BLacpEN, HeErscHEL, and several 
other English philosophers. 
At Paris he experienced marked attention from LAvoIsiER and BERTHOLLET ; 
which he ascribed partly to his having been a pupil of Dr Buack ; but was princi- 
pally, I believe, owing to his having been the first chemist who had publicly 
taught the new French doctrines in Great Britain. 
Dr Hore considered this an important era in his life, as introducing him to 
men whose names were then becoming celebrated over Europe for their skill in 
a science to which he was ardently devoted. The amiable manners and great 
abilities of LavoisiIER made a deep and lasting impression on the Scottish profes- 
sor; and few persons more sincerely deplored the sad fate of that accomplished 
man, from whom he had received the most flattering attentions. 
During his connection with the University of Glasgow, Dr Horr enumerated 
as his colleagues and hisfriends, Dr Tuomas Rep, the celebrated Professor of Moral 
Philosophy ; the eminent Mr Jonn Mitisr, Professor of Law; and Mr Grorce 
JARDINE, Professor of Logic. 
Dr Hore, for some years, entertained the wish to join the practice of 
medicine with his chemical labours; and in 1789, sought and obtained the 
appointment of assistant Professor of Medicine, and successor to his uncle Dr 
STEVENSON in the University of Glasgow. For two years he taught the Theory 
and Practice of Medicine, at the same time with Chemistry. On the death of his 
uncle, in 1791, Dr Horr became the sole Professor of Practical Medicine, and 
then resigned the office of Lecturer on Chemistry ; but he continued his private 
researches in his favourite study, the first result of which was his masterly 
paper ‘“ On a new mineral from Strontian.” 
This was communicated to the Royal Society of Edinburgh on the 4th Nov. 
1793; and it proved, what indeed had been previously conjectured by others, 
that this mineral contained a new earth, differing decidedly in its qualities from 
Barytes, to which it bears the greatest affinity. To this earth Dr Hore gave the 
name of Strontites, from the place at which it had then only been found. From 
the appearance of this mineral, which had been, I believe, first noticed, about six 
years before, by Dr Waker, Professor of Natural History in Edinburgh, it was 
generally supposed to be a variety of heavy-spar, or perhaps might contain a new 
ingredient. Yet Kirwan, in the Second Edition of his Mineralogy, published 
late in 1794, takes no notice of Strontites; except we may consider such, his 
statement, “that he had heard of the discovery of Larolite, or aerated Barytes in 
Argyleshire ;” and ScuMmEisser, whose “ Mineralcgy” appeared in London two 
years after the reading of Dr Hopr’s paper, disingenuously passing over his ex- 
periments, states, “by analysis I found it yielded 68 of Strontian earth, 30 of
