| There is a brake on one of the roughed wheels to check or stop the motion of the integraph when required. |
| Such an instrument is an integraph, and the one I have to describe to you to-night is the outcome of that inquiry. |
| The integraph draws the graph of the integral as the user traces the graph of the given function. |
| I hope the above description of the integraph may have made its construction and method of working sufficiently clear. |
| Integraph, mathematical instrument for plotting the integral of a graphically defined function. |
| In graphical dynamics the applications of the integraph seem still more numerous. |
