In 1779 Peter Woulfe examined this mineral and concluded that it must contain something new. The Spar of the Germans, said he, is commonly called white tin ore.. . . This is supposed by several to be rich in tin but the Saxon mineralogists assert that it contains none. The only experiment I made with it was to digest it in a powdered state with acids, by which means it acquires a rich yellow colour, like turbith mineral [basic mercuric sulfate] the acid of salt answers best for this experiment. This is the only substance I know of which has this property (65). 

Picric Acid (PA), discovered in 1771 by Peter Woulfe (inventor of 2- or 3-necked bottle) but not identified, was rediscovered by A. Laurent (1807—1853). He prepd it by nitrating phenol or Dinitrophenol with nitric acid and identifying it as Trinitrophenol. He did not recognize it as an expl, but found that some of its salts are expl. When the price of phenol became reasonable, PA started to be used as... 

History of Discovery. In 1779 Peter Woulfe examined the mineral now called wolframite and reported a hitherto unknown substance. Scheele, in 1781, found that a new acid could be made from tung sten (circa 1758 nomenclature for scheelite). Scheele and Bergman suggested the possibility of obtng a new metal by redn of this acid. The deElhuyar brothers found an acid in... 

The Bakerian Lecture of the Royal Society was endowed by Henry Baker, F.R.S., in his will, dated July 1763, in which he bequeathed 100, the interest to be applied for an oration or discourse to be read or spoken yearly . After his death in 1774, the first was given by the alchemist Peter Woulfe in 1775. Davy gave a succession of Bakerian Lectures from 1806 to 1810. The first, read on 20 November 1806, gave him a European reputation and gained him the minor prize of 3000 francs founded by Napoleon when First Consul, although England and France were then at war. 

Peter Woulfe ( 1727-London, 1803 or 1805) lived partly in Paris and partly in Barnard s Inn, London, where he had an untidy but well-stocked laboratory, to which his friends were invited at very inconvenient times in the night. If he took a dislike to an acquaintance he presented him with a specimen of some very rare chemical and never invited him again. He had very eccentric...
