[Data and Calculations]

Observations made to compare Green's barometer No 378 belonging to the Smithsonian Institution & observed at Milwaukee by Dr. Ch. Winkler, with Greens new Barometer No 1293 belonging to the Lake Survey under the care of I.A. Lapham.

No 378 has now been in constant use eight years, and (if the new barometer is correct) reads 3/4 of 1/10 of an inch too low.
