A rare small u-shaped mercury thermometer inscribed ‘The curved clinical. Pat 718/12 (dated to 1912).
On the other side the gradations are from 95 to 107 degrees fahrenheit. It is housed in a fitted velvet and silk lined leather case along with a silver rod which by means of a screw allows the thermometer to be secured anywhere along its length and applied or introduced to the appropriate part. Quite which part this would be is not clear. Judging by its size it is likely to have be a paediatric device and could potentially have been used in the axilla, nares, mouth rectum or vagina.
