A _Cow_ was threatened with immediate suffocation from the lodgment of a potato in the oesophagus. It had shortness of respiration, an incapacity of swallowing even its saliva, which flowed from the mouth, was in great distress, and covered with a cold sweat. Being properly secured in a horizontal posture, an external incision was made on the inside of the sterno-mastoid muscle, and a cautious dissection practised until the tumour was completely exposed. The oesophagus was divided by "an incision extending the whole length of the foreign body, which was extracted without any force, _which is almost always fatal_. I immediately made two close sutures; and also two others in the skin, on each side, adapting to them two pieces of packthread, more easily to fix the dressings. I dressed the wound with brandy, filling the opening with hemp soaked with brandy." The animal was kept on very little food or drink. On the third day the wound was dressed for the first time, and a digestive ointment applied. In the course of the 2nd week, the cicatrization of the oesophagus occurred; the part was dressed with lint; and by the 20th day after the operation, the animal was quite restored. This case would have been more useful, if more precision had been employed in describing the dressing and subsequent treatment of the wound. It would seem that the sutures were passed through the parietes of the oesophagus only, and that the external wound was kept open by being filled with tow. Certainly, union by the adhesive inflammation ought to have been attempted in all parts of the wound; but whether sutures in the oesophagus are advantageous, or whether the uniting bandage be preferable, is not so easily determined. In the two cases described in 3d vol. of the Mem. de l'Acad. de Chirur. the uniting bandage was alone employed, and with success. 50. _Retention of Urine, caused by a Stricture of the Urethra, relieved by a forcible but gradual Injection._--The editor of Le Propagateur des Sci. Med. in the No. for Feb. 1826, introduces the following case, by observing, that it reflects great honour on M. AMUSSAT, and that his discovery merits the greatest praise. M. D... aged 70 years, of a plethoric constitution, had suffered about 30 years before from three attacks of gonorrhoea; since which period he has had a difficulty in urinating, and can never discharge more than one or two ounces of urine at a time.
