X 1.--A man is brought to prison for the first time charged with a series of petty thefts committed while under the influence of drink. He shows signs of alcoholism, and is too dazed to give any account of himself. In a day or two the alcoholic symptoms have passed off and his general condition suggests enquiry. He has signs of mental disease which cannot now be confused with drink. It is found that, until a year before, he had been in business in an industrial town; that he had been a reputable citizen, quiet, peaceable, and abstemious in his habits; that he began to take to drink, and sold off his business, which realised several thousand pounds; and that he had since been lost to the knowledge of his friends. What happened in the interval I do not know. He was taken in charge by the police for stealing glasses from a public-house, weights from a shop-counter, and such-like things, which were certainly of no use to him and which he could not sell. The charge was dropped and he was sent to a lunatic asylum. X 2.--A young man is imprisoned on a charge of fire-raising. He is brisk, talkative, and cheerful, and laughs at the charge as ridiculous. Beyond showing a high appreciation of his own qualities he does not do or say anything to attract attention, and as he is really "bright" his conceit only provokes a smile. He has no physical symptoms of brain disease, and it is not suggested on his behalf that he is mentally unsound.

It was found that prisoner had always been energetic and bright at his work, and that he had good reason for boasting of his skill. His fellow-workers admitted that, though they disapproved of his bounce. He had been a teetotaler all his life and was a prominent member of a militant temperance society. He was very industrious and thrifty. He married a quiet, reputable girl who shared his opinions and ideals. He had saved some money and he suddenly made up his mind to start in business for himself. His wife did not approve of his doing so, as she did not like the risk and was quite content to go on in their accustomed ways. He persisted, and she yielded the point, but only when she saw her opposition was causing domestic strife. He rented a small workshop and furnished it. He got as much work as he could undertake--not a great amount--but before he had time to see how his venture would prosper, he conceived the idea of removing to a larger house. His wife was unable to see how he could safely do this, as she did not think he had money sufficient to justify such a course. Her opposition only made him more insistent, and on one occasion he lost his temper so completely that she became alarmed. He threatened to kill her, and looked as though he meant it. When she spoke to him about
