Bristol, 1771 



A pseudo-scientific tract, avowedly suggested by another paradoxer RICHARD LOVETT (v. No. 11048), in which the 

 author elaborates Jacob Behmen's mystic fire fluid in an attempt to explain physical phenomena, e.g. electricity, light, etc.

 told in an easy pleasant style which gives the book an exceptional charm.' Prof. Bonney, pr., F.R.S.

1 Tachenius proved himself an independent investigator, to whom chemistry is indebted both for extremely valuable 

 observations and for speculations deduced from these . . . Among his other valuable observations, he contributed 

 materially to elucidating that problem which Boyle considered the most important of all, viz. a knowledge of the 

 composition of bodies. It was with him that the first serviceable definition of the term ' salt,' as a compound of an acid 

 and an alkali, originated. His statements on the composition of various compounds show great acuteness, which is also 

 seen in the value which he laid on certain reactions as tests for different substances. Tachenius thus laid the foundations 

 of qualitative chemistry in a more systematic manner than his predecessors.' Prof. E. v. Meyer.

'Dr. Peacock [Dean of Ely] mentions Tacquet as a late instance of the old method of division. Both methods are 

 given in this translation, 'whereof the first, 1 meaning the Italian method, 'is least used but is the best ; the other most 

 used, but the difficultestV Prof, de Morgan.

 Natura Magnetis ' of Petrus Peregrinus, with whom Taisnier shared the opinion (also held by Cardan) that the magnet 

 could cause a perpetual motion. There is also at end a treatise 'de Fluxu et Refluxu Maris ' (pp. 37).

' On 25 Jan. following Faraday briefly described Talbot's independent invention of ' photogenic drawing ' at the Royal 

 Institution, and on 31 Jan. Talbot communicated an account of his researches (supra). His process consisted in produc- 

 ing the photographic image on writing-paper highly sensitised by chemical treatment. White images of the objects were 

 formed after a long exposure upon a dark ground, these being the ' negatives ', from which ' positives ' could be obtained 

 by printing in the manner still employed.' D. N. B.
