"Whistler makes dry-points mostly, and sometimes regular etchings, but the suppleness you find in them, the pithiness and delicacy which charm you derive from the inking which is done by Whistler himself j no professional printer could substitute for him, for inking is an art in itself and completes the etched line. Now we would like to achieve suppleness before the printing. I saw two prints exhibited in Paris a year or two ago; they were rather delicate, meager and thin-looking, one would have to see a whole collection in order to judge them, for doubtless he [Whistler] has done some that are first rate."
