322 M. Fischer’s Memoir of the Life of Klaproth. 
clous apartment for his labours, for his extremely valuable mi- 
neralogical and chemical collection, and for his lectures. 
As soon as Klaproth had brought the first arrangement of his 
office to perfection, — an office which, under his inspection and 
management, has always been a model of a laboratory, conduct- 
ed upon the most excellent principles, and governed with exact 
conscientiousness,— -there appeared in CrelVs Chemical Annals , 
• — in the Writings of the Society for the Promotion of Natural 
Knowledge , — in Sellers Contributions to the Science of Nature 
and of Medicine,— in Kohler's Journal , and in other periodical 
works,— a multitude of essays by him, which drew the attention 
of all chemists, and afterwards gained for him the rank of the 
first analytical chemist in Europe. Of these labours, we may 
mention only an Essay on Copal, — on the Elastic Stone, — on 
the Pearl-Salt of Proust,— on the Green Lead-Spar of Tschop- 
pau, — on the best Method of preparing Ammonia, — on the 
Carbonate of Barytes, — on the Wolfram of Cornwall, — on 
the Wood Tin-Ore, — on the Violet Schorl, — on the celebrated 
Aerial Gold, — on Apatite, — and so forth. All these labours, 
by means of which scientific chemistry was illustrated and en- 
riched, were gone through before the year 1788, when he was 
adopted as an ordinary member of the physical class of the 
Royal Academy of Sciences, the Royal Academy of Arts ha- 
ving elected him one of their members a year before. From 
this time, not only all the volumes of our academical me- 
moirs, but several of our well known daily papers, contained a 
multitude of new discoveries by this accomplished chemist ; and 
we must say, that, amidst all this crowd of his works, there is 
not one by which we have not been led to a more exact know- 
ledge of some one or other of the productions of nature or of art, 
since in these works he has either corrected false representations, 
or extended views that were before partially known, or has 
revealed the internal and formerly unknown composition and 
mixture of the parts of bodies, and has made us acquainted with 
a multitude of new elementary substances.- Amidst all these 
labours, it is difficult to say, whether we should most admire 
the fortunate genius, which in all cases readily and easily di- 
vined the point where any thing of importance lay concealed ; 
or the acuteness which enabled him to find out the best means
