^{page 65 note 1} On Miss Lang's interpretation nos. 10 and 34 of the Agora series, complete jars holding 7 Attic choes, would be decisive for her theory. For in their inscriptions she finds confirmation that they were designed to hold 8 Chian choes. But neither, I think, is certain. No. 10 has an unintelligible mark followed by eight vertical strokes and a small eta and unless we can interpret the initial mark it would be rash to assume that the strokes indicate capacity in Chian choes. No. 34 has an E followed by two vertical strokes which Miss Lang understands as half a metretes (E = hemi) and 2 choes, i.e. 8 choes. She then sees in the appearance of Chian psilosis evidence for the use of a Chian standard. But would we find with Chian psilosis an Attic use of epsilon for eta? Chian inscriptions of the fifth century are consistent in their use of eta.

Script. 202 ff.) for the volume of a pithos. Cf. Pouilloux, , Thasos i. 213 ff.Google Scholar

M. Pouilloux, impressed by the coincidence of multiples of 11 in this inscription and the letters Δl on the Chian stone and at the same time disturbed by the oddity of Διημίεκτον, would prefer to read ΔΙ ἡμίεκτον With some hesitation I reject this attractive suggestion because the significance of these multiples remains unexplained (though it should be noted that the diameter of the Διημίεκτον is very nearly 11 Ionic fingers); because I should expect some division between Δl and ἡμίεκτον because with 4,800 c.c. as half a hekteus the Chian amphora would become abnormally large.

^{page 65 note 3} It can be seen from Fig. 1 that if we exclude the immediate opening to the drainage hole the height becomes exactly 14 fingers.

×av. diameter² × height.

It was, of course, known that the volume of a cylinder was three times that of the corresponding cone.
