or verification in such a case as the present, owing to the fact that we have too few well-marked points of corôÙreôÙsponôÙdence between the one object and the other, and that especially along the shaft of such long bones as the cannon-bone of the ox, the deer, the llama, or the giraffe there is a complete lack of easily recognisable corôÙreôÙsponôÙding points. In such a case a brief tabular statement of apparently corôÙreôÙsponôÙding values of y, or of those obviously corôÙreôÙsponôÙding values which coincide with the boundaries of the several bones of the foot, will, as in the following example, enable us to dispense with a fresh equation.
| a | b | c | d | ||
|---|---|---|---|---|---|
| y (Ox) | 0 | 18 | 27 | 42 | 100 |
| yÿ£¢ãý (Sheep) | 0 | 10 | 19 | 36 | 100 |
| yÿ£¢ã° (Giraffe) | 0 | ã5 | 10 | 24 | 100 |
This summary of values of yÿ£¢ãý, coupled with the equations for the {740} value of x, will enable us, from any drawing of the oxãs foot, to construct a figure of that of the sheep or of the giraffe with remarkable accuracy.
That underlying the varying amounts of extension to which
