R. B., said to be 72 years of age, a widower, and, by occupation, a miller, was admitted on the 4th April last. The duration of his illness was stated to have been one week, but no particulars of his previous history were obtainable. He was a man of middle size, spare and decrepit. His pulse and respiration feeble, and his gait uncertain and tottering, but no particular paralysis was observed. He was quite blind from a dense cataract in each eye. He articulated fairly well, and modulated his voice, so as to give a semblance of meaning to his speech, but, when listened to, it was found to be nothing but a jabber, in which no intelligible word could be caught, and he did not appear to understand what was said to him. He took food fairly. He was restless, and inclined to wander about, but at night, in a room by himself, he rested and slept well.
