This was a lovely day and the softness of the air relieved me con-335siderably from my pain which was still however, somewhat sharp. Morning passed in reading the Massachusetts Reports, and finished the Collection of Statutes of the State from which I have gained some information. Called upon Davis and spent half an hour with him in conversation, but felt dissatisfied afterwards at the waste of time. Afternoon, Adam Smith from whom I have already gained some ideas. I went to the Theatre this evening to hear Dr. Arne’s Opera of Artaxerxes. Mrs. Austin and Mr. Horn.1 I was abundantly pleased. The former sings very well. The latter is not so highly gifted in voice. On the whole, I have seldom been better satisfied at the Theatre. The Soldier tir’d, and the Quartett of Mild as the moonbeams were exceedingly pleasing.
