Mon 4 Jan 1768: At my leisure hours this week, I read Dr. Priestley’s ingenious book on electricity. He seems to have accurately collected and well digested all that is known on that curious subject. But how little is that all! Indeed, the use of it we know; at least, in some good degree. We know it is a thousand medicines in one: in particular that is the most efficacious medicine in nervous disorders of every kind which has ever yet been discovered. But if we aim at theory, we know nothing. We are soon lost and bewildered in the fruitless search.
