NASAL INSTRUMENTS. 181 chian tube, and excite severe inflammation of the middle ear. The acci-dent is most likely to occur from the fluid being driven through the nosewith too great force, or from the patient swallowing while using the in-strument. Common salt is ordinarily employed for the purposes of irri-gation, but Weber-Liel has found that carbonate of soda is less likely toproduce a serious result, should any fluid find its way into the middle ,2 who strongly insists on the value of this method of treat-ment, has noticed that the accident generally occurs when cold, instead ofwarm water, is used ; and he calls attention to the fact that Cassels hastried it in 1,500 cases without ever having seen or heard of an untowardresult. I do not employ irrigation nearly so frequently as formerly ; not.

Spray Producers.—There are a great variety of these instruments, mostof those already described in connection with laryngeal disease (vol. i.,p. 182) being also serviceable in affections of the nose. As a rule, how-ever, it is best to use an apparatus, the nozzle of which can be passedsome distance into the nasal fossa. Two kinds of spray-producers are re-quired, viz., the anterior and the posterior. The ordinary anterior nasal spray-producer (Fig. 44) consists of a silverpipe about three inches long, terminating in a fine perforated point, andprovided with a piece of tubing and an elastic hand-ball.
