Dear Sir,

I send you annexed an extract of a Lr I have this morning received from Dr Hussey. <1> I have no instruments & never sit up to observe so that I have not seen the comet. <2>

I am very glad to hear that you have set to work seriously about your paper <3> for the Royal Society & I trust it will be finished so that it can be read at the first meeting.

Dr Lehrman [sic] <4> has in addition to Damoiseau, Pont' coulant & Rosenberger <5> determined the perturbation of the comet & arrives at very different results. According to him the comet will traverse the little bear.

Yours very truly
John Lubbock
