Pike Mercury Banjo Barometer

Description
This is a compound instrument held in a wooden frame. The large circular face is silvered. The scale around the edge extends from 28 to 31 inches of mercury, and subdivided to 0.01 inches; there are also indications for “STORMY,” MUCH RAIN,” “RAIN,” “Change,” “FAIR,” “SET FAIR,” and “Very Dry.” There is a mercury-in-glass thermometer mounted above, mounted on a silvered scale that extends from 0 to 110 degrees Fahrenheit, with indications for “Freezing,” “Blood Heat,” etc. At top there is a small gut hygrometer. A medallion at the bottom reads “B. PIKE & SONS / 518 BROADWAY / NEW YORK.” The firm was in business from 1841 to 1867, and at this address from 1855. It is difficult to know, however, whether the Pikes made this instrument, or simply sold it.
