With reference to the illustrations to your paper on the "Decussating Tracts of the Mid- and Inter-brain, &c." I have not yet received from you the drawings which, after several applications, you informed me, on August 2, you had "already commenced to get finished". As it is now nearly two years since the paper was voted for publication, it will become my duty early in January to lay the matter before the Sectional Committee appointed to advise the Council with regard to the publication of papers, and I trust that before that date I may rely upon receiving these drawings.
I am, faithfully yours,
Asst. Sec. R.S. [Assistant Secretary, Royal Society]'.
