[^1]: Agreeably to the Request of the Editors, I Have Made the Necessary Observations; and Find That My House Is Situated as Nearly as Possible W. by S. from St. Paul\'s, and That Its Elevation above the High Water Mark at Chelsea, Is Not More Than 12 or 15 Feet.

    I Have Added an Additional Column to the Present Month\'s Table, Shewing the Degrees of Evaporation by an Hygrometer, Constructed Nearly upon the Principle of Mr. Leslie\'s; and Next Month, If Agreeable to the Editors, I Propose Giving the Degrees of Heat by the Centigrade as Well as Fahrenheit\'s Thermometer, for the Purpose of Shewing the Simplicity of the One, When Compared with the Other.
