If, then, the line, _B D_ {1} _ be drawn, it is conceded that all the material within the area, _A B D_ {1} G C A_, causes direct pressure against or upon the structure, _G C A_, the vertical lines being the ordinates of pressure due to weight, and the horizontal lines (qualified by certain ratios) being the abscissas of pressure due to thrust.

To avoid the long and timeconsuming laying out of a boat by ordinates and abscissas, I have constructed a handy apparatus, by which it is possible without much trouble to obtain the sections of a vessel graphically and sufficiently accurate.

If we represent these two sections graphically by referring the magnetic moments as ordinates and the current intensities as abscissas to two coordinate axes (Fig. 2), we shall obtain for the first force the curve, O A B, which, starting from A, becomes sensibly parallel with the axis of X, and for the second the right line, O D.

In permeability curves the total magnetization of the given pieces of iron are plotted as abscissas, while the corresponding permeabilities are plotted as ordinates.

In these curves the ordinates represent the total magnetization = B =, while the abscissas represent the magnetizing force = H =.

The preceding tables, in which the ordinates represent the number of correct reproductions and the abscissas the age, are interesting.

He does not see the combinations of the abscissas and ordinates very clearly.

Never does a curve portray two or more ordinates for a single abscissa, although one of them (the parabola, curve D) has two abscissas for all positive ordinates.

I found that with each mixture there was a time of exposure which would produce the deepest blue, that with overexposure the blue gradually turned gray, and that if a curve should be plotted, the abscissas of which should represent the time of exposure, and the ordinates of which should represent the intensity of the blue the curves drawn would have approximately an elliptical form, so that if one knew the exact time of exposure which would give the best result with any mixture, one might deviate two or three minutes either way from that time without producing

Pokier knew how to find safety among the indoor abscissas and ordinates of graphs: finding the points he needed not by running the curve itself, not up on high stone and vulnerability, but instead tracing patiently the xs andjys, P (at), W (m/sec), Ti (" K), moving always by safe right angles along the faint lines ....
