13. As stated in the "Instructions for making Meteorological Observations, etc.," (Kelly & Walsh, 1892) meteorological instruments forwarded by observers who regularly send their registers to the Observatory, are verified here free of cost. During the past year 6 aneroids were verified. In addition several hundred marine barometers and anëroids on board ship were compared with the Observatory standard.
