Summary:

Explains 'discordances' as contraction of damp paper. Use 'Engraved Squares' to avoid this error. Possible error in barometer observations from Montreal. Diurnal 'undulation' appearing in data. American observations arrived, may fill 'missing intervals.' Keep record of expenses incurred. Postscript on color variation in stars.

Summary:

WB's wave models show that barometer observations will reveal atmospheric dynamics like astronomical observations revealed planetary orbits. Encourages WB to seek simple method of temperature corrections applicable to all barometers. Offers possible mechanism. Send results to B.A.A.S quickly. Will send WB's letter to [Magnetical and Meteorological] Committee.
