. Bulletin. Science. engineering," reflecting a dissatisfaction with the tra- ditional branches of engineering, kinematics was a senior subject and was taught from Rankine's Ma- chinery and Millwork}^^ At Massachusetts Institute of Technology, Peter Schwamb, professor of machine design, put together in 1885 a set of printed notes on the kinematics of mechanisms, based on Reuleaux's and Rankine's works. Out of these notes grew one of the most dur- able of American textbooks, first published in ;^ In the first edition of this work, acceleration was men- tioned only once in passing (on p. 4). Velocities in linkages were determined by orthogonal components transferred from link to link. Instant centers were used only to determine velocities of various points on the same link. Angular velocity ratios were frequently noted. In the third edition, published in 1921, linear and angular accelerations were defined, but no accel- eration analyses were made. Velocity analyses were altered without essential change. The fourth edi- tion (1930) was essentially unchanged from the pre- vious one. Treatment of velocity analysis was im- proved in the fifth edition (1938) and acceleration analysis was added. A sixth edition, further revised by Prof. V. L. Doughtie of the University of Texas, appeared in 1947. Before 1900, several other books on mechanisms had been published, and all followed one or another 11' Transactions oJ the American Society of Mechanical Engineers, 1885-1886, vol. 7, p. 757.

In addition to the work of Reuleaux and Rankine, the authors acknowledged their use of the publi- cations of Charles MacCord, Stillman W. Robinson, Thomas W. Goodeve, and William C. Unwin.
