“Though I cannot entirely agree with you in supposing that extreme study has been the cause of my late indisposition, I must yet confess that the hill of science, like that of virtue, is in some instances climbed with labour. But when we get a little way up, the lovely prospects which open the eye make infinite amends for the steepness of the ascent. In short, I am wedded to these pursuits, as a man stipulates to take his wife; viz., for better, for worse, until death us do part. My thirst for knowledge is literally inextinguishable. And if I thus drink myself into a superior world, I cannot help it.”
