    the Conversation-tube, is well known, and has many patrons, especially among the ladies. When not in use, it can be conveniently deposited in the reticule, and there is an elegance about it which the others do not possess, and this is some recommendation. Moreover, it is a most efficient apparatus, and for the very deaf the only instrument which will answer the purpose. Unfortunately, it is only adapted to carry on conversation with a single person, who is required to speak into the funnel-shaped extremity; but this disad- vantage is in some measure counterbalanced by the length and flexibility of the tube, by which a person is enabled to hold conversation at a distance of two or three yards, if the tube be so long. The Ear-cornets which are fixed into the ears, and retained there by a metallic spring, which, passing over the head, connects them, have been in use chiefly because they leave the hands at liberty; but as far as I have had opportunities of observation, they are soon laid aside as ‘more plague than profit;” for unless the nipple is ac- curately adjusted and retained in the passage of the ear, the instrument fails. The fact is, the hand is necessary to preserve the nice adjustment of the nipple in this or in any other instrument. The same observations hold good with regard to an instrument made use of by a distinguished judge, one of the kind patrons of the Ear institution. Seeing it to be of such service in his case, I was induced to recommend a trial of it to others, but I am not aware of any one else having adopted it. It is somewhat upon the same principle as the ear cornets; but the receptacle for sound, instead of being situated in front of the ear, opens in the centre of the instrument on the top of the head.
