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



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

 '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 contributedi 

 materially to eluci<lating 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 fordiff'erent substances. Tachenius thus laid the foundations 

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

The second work published on thk maonet, and of extreme rarity. It is mainly based on the ' Opusculum de

' 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 {mpra). 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.
