The following account is practically identical with section (a) of my Report to the Cretan Committee of the British Association (cf. Reports, Section H, 1903, Southport meeting). On the 26th March, 1903, the day of my arrival at Palaikastro, I commenced work on the ossuary discovered and partially excavated in the preceding year (cf. Report by R. C. Bosanquet, in Man, 1902). The work consisted in exposing the crania in the several compartments of that enclosure, and I soon found that the only reliable method of obtaining satisfactory cranial measurements was to clear away the surrounding earth from each skull and to measure while the specimen was still in situ. Subsequently, each skull (to the number of about thirty) was carefully removed, and then, moistened paper having been spread over and around it, a covering of plaster of Paris was finally applied: in this way it was hoped to render the skulls less liable to destruction in the transit to Candia or to such other destination as might be determined upon.
