Unidad documental simple 13 - 'Tangrams. Constructions and Rough Copy'

Typescript, MS and illustrations in both pencil and pen. 3 unnumbered sheets; ff. 1-108 (includes both 3a and 3b, 4 and 4b), all fastened together with butterfly clip.
With envelope.

Includes copy letter from Rouse Ball to Herbert Allen Giles, 4 May 1913, asking whether he knows of a 'classical [Chinese] series of seven volumes of such diagrams [tangrams] with about 1000 diagrams in each volume', and whether there are any Chinese collections of tangrams in the British Museum or the Cambridge University Library. Giles's reply, 6 May 1913, is also included; he has never heard of anything like the seven-volume work, and having checked the catalogues of the British Museum and the University Library, can only find the 'small 2. vol. work' he mentioned to Rouse Ball or his wife 'long ago' (CUL F 126-129). Main text includes many examples of tangram figures, with page references for unnamed book.
