I was first called to William G----, a very ingenious artist, when he lay under a severe attack of what we call _delirium tremens_, or temporary insanity, produced by, or consisting of (for the proximate cause is often the disease itself), highly irritated nerves, the consequence of a succession of drinking fits. I found that he had been "on the ball," as they say, for three weeks, during which time he had drunk forty-two bottles of strong whisky. Like many other people of genius, whose fits of inspiration (for artists have those fits as well as poets) make them work to excess, and leave them, as they wear out, the victims of ennui and lassitude, he was in the habit of applying himself to his business with too much assiduity, for the period, generally, of about a month. Exhausted by the excitement of thought and invention kept up too long, he fell regularly down into a state of dull lethargy, which seemed to be painful to him. He felt as if there was a load upon his brain. A sense of duty stung him, after a few days' idleness, poignantly; and, while he writhed under the sting of the sharp monitor, he felt that _he could not_ obey the behest of the good angel; and yet could not explain the reason of his utter powerlessness and incapacity for work. If he had allowed this state, which is quite natural, and not difficult of explanation, to remain unalleviated by stimulants for a day or two, he would have found that, as the brain again collected energy, he would have been relieved by the _vis medicatrix_ of nature herself; but he had no patience for that; and drink was, accordingly, his refuge and relief. The first glass he took was fraught with the most direful power--it threw down the floodgates of a struggling resolution; the relief of the new and artificial impulse raised his spirits: another application inflamed his mind; and then bottle after bottle was thrown into the furnace, until the drink-fever laid him up, and brought upon him the salutary nausea which overcame the rebellious desire. This system had continued for more than ten years. He had been gradually getting worse and worse; and, latterly, he had resigned himself to the cognate influence of the narcotic weed.
