English: Part of a 9th century Latin manuscript. From [1].

The text seems to read:

Fluuius quem heridanũ

dicunt hab& stellas pri

mo flexu iii scđo iii ter

tio vii quae dicuntur

ora nili summa xiii

huic sub ẽ stella quę

canopus appellatur.

In standard orthography:

Fluvius quem Eridanum dicunt habet stellas primo flexu III, secundo III, tertio VII, quae dicuntur ora Nili, summa XIII, huic sub est stella quae Canopus appellatur.

In English:

The river that they call Eridanus has three stars in the first bend, three in the second, and seven in the third, which are called the mouths of the Nile, (for a) total of 13, (and) under this is the star which is named Canopus.
