Reed this paper for publication in Philosophical Transactions. Miller referred to as it `a substantial and crucial addition towards the expertise of diamagnetism’. Thomson was not so convinced, writing: …there is certainly so much of critical and curious experimental investigation in it…as to totally entitle to a spot inside the Transactions… Nevertheless I consider that…Mr Tyndall is frequently contending against an imaginary adversary…Feilitsch (sic) “theory” is founded on a error…all Mr Tyndall’s experiments and views are in ideal accordance with those indicated by Faraday in the starting and advocated by252 253Tyndall, Journal, 3 October 854.

Thomson wrote that he would want for some modification to become produced `in the controversial part from the communication’ but `should Mr Tyndall be disposed to create no alter, I need to advise its publication since it stands’. Within this paper, published as the `Fourth Memoir’ in Researches on Diamagnetism and Magnecrystallic Action, Tyndall set out his view from the significance of structure, `Indeed it might be safely asserted that each and every force which makes matter its car of transmission must be influenced by the manner in which the particles are grouped together…no matter whether we take the old hypothesis of imponderables or PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/9727088 the new, and much more philosophic a single, of modes of motion’, and described in the first part of the paper his experiments on the influence with the molecular structure of wood upon its magnetic deportment. His view 
on polarity can also be stated `The magnetic force, we know, embraces each attraction and repulsion, therefore exhibiting that excellent dual action which we’re accustomed to denote by the term polarity’. Detailed experiments are reported around the movement of bars and spheres of different substances, diamagnetic and paramagnetic, when placed between pointed poles, either straight in line among the poles or above or under them, exploring no matter whether the bars or the crystallographic axes (or axes of compression) of spheres set axially or equatorially. The clear conclusion is that the position taken up by spheres depends on molecular structure, though a further action comes into play with elongated bars, due to the magnetic force, or couple, around the end in the bar, which can overcome the effect of structure. In all cases diamagnetic and paramagnetic substances behave as complet.
