For ten days, the patient had not been able to swallow anything but about a quart of milk or bouillon in small doses. As soon as he had swallowed the liquid, he experienced distress over the pit of the stomach, followed by painful regurgitations. For three days, every attempt made by Dr. Terrillon to remove the obstacle that evidently existed at the level of the cardia entirely failed. Several times after such attempts a little blood was brought out, but there was never any hemorrhage. The patient suffered, grew lean and impatient, and was unable to introduce into his stomach anything but a few spoonfuls of water from time to time. As he was not cachectic and no apparent ganglion was found, and as his thoracic respiration was perfect, it seemed to be indicated that an incision should be made in his stomach. The patient at once consented. The operation was performed February 9, at 11 o'clock, with the aid of Dr. Routier, the patient being under the influence of chloroform. A small aperture was made in the wall of the stomach and a red rubber sound was at once introduced in the direction of the cardia and great tuberosity. This gave exit to some yellowish gastric liquid. The tube was fixed in the abdominal wall with a silver wire. The operation took three quarters of an hour. The patient was not unduly weakened, and awoke a short time afterward. He had no nausea, but merely a burning thirst. The operation was followed by no peritoneal reaction or fever. Three hours afterward, bouillon and milk were injected and easily digested. Passing in silence the technical details, which would not interest the majority of our readers, we shall be content to say that Mr. X., thanks to this alimentation, has regained his strength, and is daily taking his food as shown in Fig. 1. The aperture made in the stomach permits of the introduction of the rubber apparatus shown in Fig. 2, the object of which is to prevent the egress of the liquids of the stomach and at the same time to introduce food. A funnel is fitted to the tube, and the liquid or semi-liquid food is directly poured into the stomach. Digestion proceeds with perfect regularity, and Mr. X., who has presented himself, of his own accord, before the Academy, and whom we have recently seen, has resumed his health and good spirits.--_La Nature._ * * * * * HOW TO CATCH AND PRESERVE MOTHS AND BUTTERFLIES. There is no part of our country in which one cannot form a beautiful local collection, and any young person who wants amusement, instruction, and benefit from two, three, or more weeks in the country can find all in catching butterflies and moths, arranging them, and studying them up.
