What reading level is The Theory of Valency book?
To quickly assess the difficulty of the text, read a short excerpt:
This result, however, cannot be accepted as final. It must not be forgotten that Baker and Bennett also analyzed the hydrated telluric acid, but obtained inconstant results, the variation in 26 deter- minations being from 126*8 to 128*2. This they attribute to inconstancy in the amount of water of crystallization. 3 Marck- wald only performed six experiments, and it has yet to be proved that the constancy of his results was not due to coincidence. Further, if this lower number is accepted, an e...xplanation will have to be given for the higher values repeatedly obtained by every other method.
Bettel, 4 in a very interesting communication to the Chemical NewS) has raised the vexed question again as to the possibility of tellurium being a mixture of two elements. Observing in 1883 tnat some silver obtained from assays of a silver telluride ore behaved in an unusual manner at the apparent completion of cupellation, Bettel endeavoured to determine the cause. The results of his experiments, performed in order to deter- mine if a new element were present, were inconclusive, and by giving publicity to the fact he hopes to draw the attention of scientific and commercial men to this unsolved problem.
