TUITION BY CORRESPONDENCE
REQUIRED, EXPERT OPINIONS, solely in the interests of Science, upon a treatise on the Constitution and Structure of Atoms, which claims, among other deductions, to have established the following new Chemical Law :-" The acidicity or non-metallic
ature of an element is always due to a pair or pairs of electro-positive forces, each pair emanating from a portion of the element, of which the mass is 4, taking the mass of an atom of Hydrogen as unity.”

The deductions have been obtained by pure reasoning upon observed facts, and await experimental confirmation.
The latest expert opinions are as follow :-
(2) You are the first, I believe, to have given us what I consider the most tangible base lines upon which one may hope to fathom the causation or matter as we know it.
(3) There is truth on the face of it.
