Incomplete letter from Alex [Alexander] Larmor, to [Joseph Larmor] Commencing mid-way through an explanation of an experiment on light bands and the rotation of the Earth on its axis. A negative result would have shown [Augustin-Jean] Fresnel to be correct. He might try the experiment himself and snds a manuscript [not present] so that Joseph can find any errors and whether it could be carried through. He asks how much residual charge in a Leiden jar is due to polarization. A radioactive body would dischsrge a Leiden jar, he supposes. A pencil note in the margin reads 'Oct 05'. October 1905 [?]
