152 Archaeology in Egypt Studies, vol. 2), London, 1911, is an argument that no. 87 furnishes the means for ﬁxing the date of the Hyksos period. With two of the three assumptions here made by Petrie, Peet (1923, 2), p. 130, has no sympathy.

These articles are valuable, especially in the last volumes. Quotation (first paragraph vol. 16, p. 164): "Two years and a half elapsed since my last notes on the Rhind Papyrus were published: on proceeding with it it became evident that the metrology of Ancient Egypt ought to be thoroughly worked over as a preliminary study, in order to give a better mastery of the subjects dealt with in this important document. My notes were soon afterwards ready to be issued, but other matters have interfered with their publication until the present time, and in some ways they have proﬁted by the delay. I do not pretend to have solved all the problems that were outstanding after Professor Eisenlohr's edition, but I have done what I can to supply certain new information about the papyrus itself, and to make such observations as are calculated to render the study of the document easier to those who have not hitherto paid special attention to ancient Egyptian Arithmetic and Metrology."

A Greek papyrus not earlier than the sixth nor later than the ninth century, and hence it is almost our latest mathematical document to exhibit the methods of Egyptians 2500 years earlier. The papyrus contains a set of tables and 50 problems. The tables give (pp. 24-31): (1) the products of 2, 3,. . ., 10, 20,30, . . ., 100,200, . . ., 1000,2000, . . ., 10000, by ⅓, ⅔, ¼, $1/undefined$, $1/undefined$, $1/undefined$, $1/undefined$, $1/undefined$,$1/undefined$ (2) the products of 1, 2,. . ., and n by $1/undefined$, n= 11, 12,
