On the 27th I was so sharply troubled with toothache after dinner that I sent for the doctor, who, when he had taken account of all the symptoms, and had marked especially that the pain subsided while he was there, decided that this was no material fluxion, but one extremely subtle, and little else than wind which ascended from the stomach to the head, and, having mixed itself with the humours there, caused this disorder. This opinion seemed to me reasonable, seeing that I had often suffered from similar seizures in other regions of my body. On Monday the 28th of August I went at dawn to the Bernabo spring and drank over seven pounds thereof. I am sure this draught gave me the vapours and made my head ache, and on Tuesday I drank nine pounds from the common spring and felt my head affected immediately after. In sooth my head was in very bad case, having never recovered from the effects of the first bath I took. It has pained me less often of late, and in a different way, as it has not weakened me or dazzled my eyes as it did a month ago. I suffered chiefly in the back, and pain never attacked my head, but it flew to my left cheek, affecting all parts thereof, the teeth down to the very roots, the ear, and a portion of the nose. The pang would be brief, but as a rule sharp and burning, and wont to attack me frequently both night and day. This is how my head fared at this juncture. I am firmly convinced that the fumes of this water both in drinking and in bathing--though I hold drinking to be the worse--are very bad for the head, and even worse for the stomach. And on this account the patients here are forced to take medicines to correct the action of the water. On the Thursday I gave up drinking and rode in the morning to see Costrone, a large village in the mountains. I found many fine and fertile level spaces and pasturage to the very tops of the mountains. To this village are attached several hamlets with comfortable houses roofed with stone. On my way back I made a long circuit through the hills. My head meantime continued in its usual condition--to wit, a bad one; I began to get weary of these baths, and if I had received from France news for which I had been waiting--indeed for four months I had heard nothing at all--I should have set forth at once and finished my autumn cure in some other bath. In travelling towards Rome the baths of Bagno Acqua, Siena, and Viterbo would lie but little off the main road; and towards Venice I should pass near those of Bologna and Padua.
