    cases of amaurosis and one of ptosis are recorded by Mr. Hancock* as cured by the removal of decayed or overcrowded teetli. Mr. Fleischmannf gives a case in which an obstinate muco-purulent discharge from the right nostril, which had resisted other treatments, yielded to extraction of the right upper canine. Plucking the large vibrissse at the entrance of the nostrils will, at least in some persons, cause a notable secretion of mucus, evidently dependent on the pain excited. Some while ago, I had a gentleman under my care with acute rosacea of the face and head, and chronic corneitis, with vascular development on the cornea. I applied on one occasion some liq. plumbi diacet., diluted with an equal amount of water, to the upper lids (everted), which I found very red. This caused excessive irritation ; the eyes became greatly congested, watered extremely, and were very painful; while the skin of the face, the nose especially, became of a deep red, and all the vessels of the face much congested. There was extreme photo¬ phobia. It was half an hour before the hypersemia began to subside. The irritation in this case evidently was reflected from the branches of the first division of the fifth nerve supplying the lids, on to the vaso-motor nerves of the arteries, supplying the skin of the face, which, in consequence of the morbid impression, became dilated—not contracted, as they normally should, accord¬ ing to the law of reflex action. This was a marked example of inhibitory action. Dr. Brinton informs me that he has long held and taught a view almost identical with the above, under the name of “ reflex relaxation.” The pathology of these cases is, no doubt, the same ; a nerve of special sense, a musculo-motor or a vaso-motor * “Lancet,” January 22, 1859. t “ British Medical Journal,” April 9, 1859.
