MY DEAR DAVIDSON,--I am in receipt of two letters from you since my last, the latest one of them from Capri. I am very sorry to hear of your continued bad physical condition. You have a queer constitution,--with such an unusual amount of strength in most ways,--to be a constant prey to ailment. I have long ago come to think that the right measure of a man's health is not how much comfort or discomfort he feels in the year, but how much work, through thick and thin, he manages to get through. Judged by that standard, you doubtless score an unusually high number. But when I hear you talking about Texas, I confess I really begin to feel alarmed. From Rome to Austin! How can you think of such a thing? Are you sure M---- is not playing the part of the tailless fox in the fable? I know not a living soul in Texas, and if I did I should have moral scruples about becoming an accomplice in any plot for transporting you there. Why is it that everything in this world is offered us on no medium terms between either having too much of it or too little? You pine for a professorship. I pine for your leisure to write and study. Teaching duties have really devoured the whole of my time this winter, and with hardly any intellectual profit whatever. I have read nothing, and written nothing save one lecture on the freedom of the will. How it is going to end, I don't well see. The four months of non-lecturing study I had at home last year, when I slept well and led a really intellectual life, seem like a sort of lost paradise. However, vacations make amends. This summer I am to edit my poor father's literary remains, "with a sketch of his writings" which will largely consist of extracts and no doubt help to the making him better known. You ask why I don't write oftener. If you could see the arrears of work under which my table groans, and the number of semi-business letters and notes I now have to write with my infernal eyesight, you would ask no longer. In fact I am beginning to ask whether it be not my bounden duty to stop corresponding with my friends altogether. Only at that price does there seem to be any prospect of doing any reading at all.
