Seldom has head ache afflicted me as that did last night. The back part of the head and neck were still painful this morning. Returned to Boston driving Abby in with me. Commencement day at Cambridge. Feeling still very unwell, I dispatched a Note to Abby1 declining a party at her Sister’s, Mrs. P. C. Brooks Jr., and proceeded to Quincy to mend myself. My father returned from his ride shortly after. Went to bed shortly.
