The Boreal Arrow 

Code BA12041733: Antique English Leather-Cased Thermometer and Compass, c. 1830

 

This is a unique and extremely rare thermometer and compass made around 1830. This date can be determined by the vivid red color of the leather case and also by the crown shaped cap. The leather covered wooden case is in excellent condition with no loss of leather. It has a strong hinge, opens and closes properly by using the small hook. The compass and thermometer are placed on a disc made entirely of Mother-of-Pearl. Even the small cylinder that houses the compass is made of Mother-of-Pearl.  There is no damage to the base: no cracks or chips. The base is marked with two temperature scales: Fahrenheit and Celsius. The scales are graduated in degrees. It says FREEZING at 0°C, TEMPERATE at 10°C, SUMMER HEAT at 20°C and BLOOD HEAT at 30°C. The markings are sharp and can be read easily. The thermometer is in working order and reads the correct temperature even after 150 years. The compass has an enamel dial and a crown shaped needle cap. It is covered with a thick slightly convex glass crystal. Crystal and dial are free of chips and scratches. The compass is in working order and finds North without any problem. It measure 76mm in diameter. This is an extremely rare find and still in excellent condition.
