Ing the outcome of Weber he has proved the production of diamagnetic polarity’, thereby putting himself firmly in the nonFaraday camp. Thomson merely commented `it is effectively suited to publication within the Transactions’. At this point, again, Tyndall’s capability as an experimentalist showed itself. Working with equipment developed by Weber he made a series of extremely sensitive experiments with copper, antimony and with insulators, employing glass and six other components, and found deflections to become permanent in lieu of short-term, which would be the case if there had been a momentary induced present. In his terms this showed the polarity of a diamagnetic body as an insulator in addition to that of conductors. In addition he diplomatically noted that his gear was sensitive sufficient to create clear deflections, in contrast to the gear earlier made use of by Faraday, who because of this had stated that he could `find no experimental evidence to assistance the hypothetical view of diamagnetic polarity’. Tyndall ended the paper claiming that all objections to diamagnetic polarity had now fallen away, placing it `among by far the most firmly established truths of science…The bring about of science is more genuinely served, even by the denial of what may be a truth, than by the indolent acceptance of it on insufficient grounds. Such denials drive us to a deeper communion with Nature, and, as inside the present instance, compel us through serious and laborious enquiry to strive immediately after certainty, instead of resting satisfied, as we are prone to accomplish, with mere probable conjecture’. Tyndall’s final and comparatively brief paper, the Sixth Memoir, `On the Relation of Diamagnetic Polarity to Magnecrystallic Action’,327 followed the Fifth very promptly and was in reality published in Philosophical Magazine in February 856 before the Fifth, in September 856, although the latter had been published earlier in Philosophical Transactions. Within this paper, mainly addressing Faraday’s statement that the magnecrystallic force is neither attraction nor repulsion, he gave a clear explanation from the complicated effects of attraction, repulsion as well as the impact in the resulting moments, or couples, in explaining the path of movement of spheres and bars of substances in diverse magnetic circumstances. In distinct, he showed that a recession in the pole could be as a consequence of differential attraction and repulsion, i.e. to a `polar’ force, `The most difficult effects of magnecrystallic action are hence lowered to mechanical complications of32 322 323 324 325 326Tyndall, Journal, six December 855.

All through this time Tyndall demonstrated his capabilities as a systematic experimentalist which are far more widely known through the subsequent function on radiant heat and spontaneous generation. His certain contribution to diamagnetism was to esta.
