Pages 161-243 of this history [a copy of which, so far as published, is in the library of the late Dr. G. Enestrom, now the property of the Hogskola, Stockholm] deal with Egyptian fractions. Pages 161-198 appeared as supplementary to volume 11 of the periodical for the year 1892, with title page dated 1898. Pages 199-243 were supplementary to a later undetermined volume.

Makes note of three "remarkable similarities" between the Kahun and Rhind papyri. Compare Griffith (1897).

Transcription and translation, with commentary, of a Greek papyrus (size 21.30 × 40.5 cm.) which originally formed part of a papyrus roll and appears to have been found in the Fayûm, near the pyramid. It was probably written about 150 A. D. Each of the three problems in the papyrus is to ﬁnd an area: (1, 2) of a quadrilateral, two of whose sides are parallel 2-6 and 16-10 units respectively, and whose other sides are 13-13 and 15-15, (3) of a rhombus one of whose sides is 10 units and one of whose diagonals is 12 units long. In the course of the discussion of the first problem part of the work corresponds to solving the simultaneous equations x$2$ — y$2$ = 56, x + y = 14.
