GEORGE WASHINGTON (1732-1799). First President of the United States; Commander-in-Chief of the Continental Army; President of the Constitutional Convention and signer of the U.S. Constitution. 8” x 4”. Autograph note entirely in Washington’s hand. (circa 1796). “Pray get me one of those Thermometers that tells the state of the Mercury with in the 24 hours – Doct’r Priestly or Mr. Madison can tell where it is to be had. – Perhaps the old one, if nothing better may do to present to Mr. Snowden according to his letter to me – left with you.” Washington’s diaries show a farmer’s preoccupation with the weather. The first mention of the thermometer therein appears to be January 9, 1785; thereafter daily entries made at Mount Vernon almost always refer to the mercury of the thermometer, usually with readings taken three times each day.
