orbing occupations the problem of
the _Odyssey_. Thus he had little leisure or energy for the labour of
painting; and this labour was always great. He could not leave his
outline until he had got it right, and there was a perpetual chase after
the changing shadows. And when he had got the outline it was so
constantly disappearing under the colour that he took to making "a
careful outline on a separate sheet of paper"; this was to be kept, after
he had traced the drawing on to the paper which was to receive the
colour, and to be referred to continually while he proceeded. When he
met with the camera lucida, which he bought in Paris, and which is among
the objects given to St. John's, he thought his difficulties were solved
and wrote to Miss Savage, 9 October, 1882: "I have got a new toy, a
camera lucida, which does all the drawing for me, and am so pleased with
it that I am wanting to use it continually." To which in 1901 he added
this note: "What a lot of time I wasted over that camera lucida, to be
sure!" It did all the drawing for him, but it distorted the perspective
so that the outlines of the many sketches which he produced with its help
were a disappointment.

The camera lucida having failed, his hopes were next fixed upon
photography, which, by rapidly and correctly recording anything he felt a
desire to sketch, was to give him something from which he could
afterwards construct a picture. So he took an immense number of snap-
shots, of which many are at St. John's, but he never did anything with
them. Nos. 62 and 63, which were done by Sadler from Butler's
photographs, show how he would have proceeded if he had not had too many
other things to do.

It was not until 1896, when _The Life of Dr. Butler_ appeared, that he
was able to return seriously to sketching, and by that time he was over
sixty and too old to be burdened with the paraphernalia necessary for
oils; he therefore confined himself to water-colours.

Some of the pictures in this list were included in the list in _The
Eagle_, vol. xxxix., no. 175, March 1918, and the remainder in the
succeeding number, June 1918. In making the present catalogue I have
corrected such errors and misprints as I noticed in _The Eagle_, and I
have re-arranged and renumbered the items so as to make them run in
chronological order. I have also amplified some of the notes. I have
placed the sketches and drawings in order of date because to examine them
in that ord
