โœฆ Synopsis

The resistance of the atmosphere also varies as the square of the speed.

The train displaces a volume of air somewhat wider than the cars, which it carries along with it, and which causes an additional resistance by its friction against the surface of the ground.

The following are the directions and velocities of the wind during the three days on which data were taken, which I have obtained from the U. S. weather signal office in Boston. Record 01 R&d.-Wednesday, March 15 : general direction, W.; velocity, at 11.30 A. M., 36, at 12.35 P. M., 48 miles per hour. Thursday, March 16: direction, veered to E., at 9.40 A. M.; velocity at 11 A. M., at Boston, 20 miles per hour. Thursday night at midnight, 30 miles per hour. Friday, March 17 : direction, wind continued E. till Friday noon ; velocity, at 11 A. M., the maximum, 24 miles per hour, when the direction changed to N. E., and at 12.43 P. M., to N. W.

Now this is diminished by the volume of the internal staying, and, although it was supposed that this would be inconsiderable, a correction was made for this. The arrangement of these stays caused the quantities by which the capacity was to be corrected, to be of two kinds. First, a constant correct
