The wall of the old houses runs towards the gate of San Nicolo.
[Footnote: By the side of this text there is an indistinct sketch, resembling that given under No.973. On the bank is written the word Casace. There then follows in the original a passage of 12 lines in which the consequences of the windings of the river are discussed. A larger but equally hasty diagram on the same page represents the shores of the Arno inside Florence as in two parallel lines. Four horizontal lines indicate the bridges. By the side these measures are stated in figures: I. (at the Ponte alla Carraja): 230—largho br. 12 e 2 di spoda e 14 di pile e a 4 pilastri; 2. (at the Ponte S. Trinita); l88—largho br. 15 e 2 di spode he 28 di pilastri for delle spode e pilastri so 2; 3. (at the Ponte vecchio); pote lung br. 152 e largo; 4. (at the Ponte alle Grazie): 290 ellargo 12 e 2 di spode e 6 di pili.
There is, in MS. W. L. 2l2b, a sketched plan of Florence, with the following names of gates: Nicholo—Saminiato—Giorgo—Ghanolini—Porta San Fredian —Prato—Faenza—Ghallo—Pinti—Giustitia.]
