In W. E. Crum, Short Texts from Coptic Oslraca and Papyri, Oxford, 1921. number 442 (p. 115) is a transcription, without translation, of a 11 line pottery tablet in the Manchester University Museum. It appears to be a table of numbers, the total of which in each of the ﬁrst seven lines is equal to 17; but the purpose is obscure. The number in the Museum catalogue is 6221.

Compare under 1900 for an account of the larger fragment. We have here a problem similar to that in the larger fragment, and leading to the equations x$2$ + y$2$ = 400, x :y = 2 : 1½. The facsimile of the smaller fragment is given on the same plate as that containing the larger.

Very numerous references in the index under: "Ägyptische Geometrie," "Ägyptisches Rechnen," and "Ahmes."

An interpretation of problem 60, of the Rhind papyrus, without emendation of the text; refers to Borchardt (1893). This note was corrected in Schack-Schackenburg (1904, 1).

, "Breve storia dell' aritmetica e dell' algebra nei tempi antichi," Il Pitagora, vol. 10, Nov., 1903, pp. 14-19.

These pages in a series of articles, deal with "Aritmetica ed algebra presso gli Egiziani;" there are references to Eisenlohr (1877, 1891), Sylvester (1880), Loria (1892, 1893, 1894), and Baillet (1892). Practically the same material is given in Chapter II, pp. 17-25, of G. Fazzari, Brave Storia della Matematica dai Tempi Antichi al Media-e-vo, Milano, [1907].

Not important in this connection.
