Aneroid barometer

A barometer is an instrument used to collect meteorological data by measuring changes in atmospheric pressure. According to the inscription, this barometer was designed to forecast the weather in the Philippine archipelago, as proposed by Father Federico Faura.

Federico Faura (1840–97) was a Spanish Jesuit priest who taught mathematics and created the Observatorio Meteorológico del Ateneo Municipal de Manila, now known as the Manila Observatory. Faura is considered to be one of the 19th century's great scientists and a founding father of cyclonic meteorology. He was the first director of the Manila Observatory, which became a key institution for the forecasting system and climatology studies in the Philippine archipelago.
