About this object

Envelope; a small brown paper envelope with the pre-printed text Form 399 / AIR MINISTRY / METEOROLOGICAL OFFICE, LONDON / MUSLIN & WICK / FOR / WET BULB THERMOMETER / Change every 3 weeks or oftener if necessary. / Use one thickness of muslin, and three strands of cotton / looped double'. Enclosed inside the envelope are small white muslin strips with cotton thread attached. The number '16' is written on the envelope in orange crayon or pencil.

This object is probably original to site. After the death of the Reverend Alexander Don in 1934 the responsibility for keeping meteorological records seems to have fallen on the postmistress at Ophir Post Office, Mrs Drake. Don (and later Mrs Drake) recorded temperature and other weather phenomenon on behalf of the Met Office.
