June 4. — Went about Diodati’s house. Then to see Shelley, who, with Mrs. Shelley, came over. Went in the evening to a musical society of about ten members at M. Odier’s ; who read a very interesting memoir upon the subject of whether a physician should in any case tell a lover the health [of the lady of his affections], or anything that, from being her physician, comes to his knowledge.
Afterwards had tea and politics. Saw there a Dr. Gardner, whom I carried home in the caleche. Odier invited me for every Wednesday.
Came home. Went on the lake with Shelley and Lord Byron, who quarreled with me.
