Very unexpectedly we perceived the sky overcast this morning and it rained very heavily all day so that nobody went to town. I passed my time quietly enough. My difficulty is only in the coldness of the weather which prevents my sitting with comfort away from a fire. Read German this morning, this being my month according to my plan of studying the languages alternately. Also Hume System of Morals founded upon Utility. Very questionable. Wrote part of an Essay upon our affairs. Afternoon Mandeville and Ovid. Evening, History of Maritime Discovery,1 the early adventures in South America, very interesting, but a very black page in European History.
