operatee

It is necessary to begin with coarse preparatory tests, to accustom the operatee to the character of the work.

The operator finally records the scale interval that the operatee can just appreciate, as being the true measure of the coarseness (or the inverse measure of the delicacy) of the sensitivity of the operatee.

The testing is performed by handing pairs of weights to the operatee until his power of discrimination is approximately made out, and then to proceed more carefully.

The most perfect way would be to drop the weights, each in a little bag or sheath of light material, so that the operatee could not see the weights, while the ratio between the weights would not be sensibly changed by the additional weight of the bags.

Similarity in outward shape and touch was ensured by the use of mechanically-made cartridge cases; dissimilarity through any external stain was rendered of no hindrance to the experiment by making the operatee handle them in a bag or with his eyes shut.

The tests show the sensitivity at the time they are made, and give an approximate measure of the discrimination with which the operatee habitually employs his senses.

It is best now, for reasons stated in the Appendix, to hand to the operatee sequences of three weights at a time, after shuffling them.

To this one of the ponies whinnied softly, and then moved gently to its companion's side, head to tail, bared its big teeth as if to bite, and began to draw them along the lower part of the other's spine, beginning at the root of the tail and rasping away right up to the saddle, while the operatee stretched out its neck and set to work in the same way upon the operator, upon the give-and-take principle, both animals grunting softly and uttering low sounds that could only be compared to bleats or purrs.
