The settlement of this affair must have been one of Lord Lyons's last transactions with the American Government, for upon his return to Washington his health rapidly grew worse, and as scarcely any letters from him are to be found between the end of October and the middle of December it is to be presumed that he was so incapacitated that the work devolved upon Mr. Burnley. Early in November he was forced to apply for leave, which was granted in December.

I am truly obliged to you for so promptly sending me leave to come home. When I wrote to you on the 1st of last month to ask for it, I hardly expected to have such urgent need of it as I have now, but a few days afterwards I became so ill as to be utterly unable to do any work. I have not made any satisfactory progress towards a recovery, and am scarcely in a state to travel. There seems however to be no prospect of my getting any better while I stay here, and I shall therefore, if possible, set out for New York to-morrow, in the hope of being able to embark there for England on the 14th.

I am told that the American papers have stated that I have been dangerously ill with typhoid fever. I have had no fever at all. My principal malady is a nervous headache.

In letters to other correspondents he explained that being quite unable to work he considered himself simply an impediment to the transaction of public business, and was going away simply on leave of absence. During the last few days of his stay in America he was too unwell to write, or even, as he explained to Mr. Seward, equal to a conversation, and it was doubtful whether he would be well enough to travel. Accompanied, however, by Mr. Sheffield, he embarked at New York and arrived in London during the closing days of December.

The fact was that he had completely broken down under the continuous strain of the last four years, and in view of the circumstances it was not surprising. Some idea of the work at Washington may be gathered from the following official figures.
