"Catal. Scientif. Papers" ['Catalogue of Scientific Papers']
The slips at present in your hands will be sufficient to finish the first of the three volumes which form the new decade. I should be glad to know whether you think we ought to have a proof binding, or whether it will be sufficient for you to take a volume from the previous decade as pattern. The binding should of course accurately match that of the previous decade.
