Caste of Physicians
Fourth of the High Castes.

This is the caste of those who concern themselves with the healing arts. Surgeons, apothecaries, medical researchers and health practicioners are all members of this caste. Universally recognized as non-combatants during time of war. Their caste color is Green.

The instruments he used, the tests he performed, the samples he required were not unlike those of Earth. Of special interest to me was the fact that this room, primitive though it might be, was lit by what, in Gorean, is called an energy bulb, an invention of the Builders.

In this he would place slides, containing drops of blood and urine, flecks of tissue, a strand of hair.
