A sea fog from the Eastward covered every thing up and prevented my being able to go to town as I intended. The greater part of my morning was therefore devoted to the comparisons of the copy of the old journals with the original which I pursued steadily and executed a great deal of. This is necessary as a first step. I find much that is interesting and much that is only amusing in the examinations. But it cannot be done with much rapidity.

Afternoon, a succession of thunder showers with at times very heavy rain, and sharp lightning. This is a position from which there is a great opportunity of witnessing all these results, and they are at times fearfully sublime. Mrs. Adams who was riding came home in the shower, bringing with her E. C. Adams who remained to drink tea and I returned with her in the evening. Read Pliny and Grahame. Quiet evening at home.
