Description

The text describes the constellation 'Tropicus Capricorni'. Includes a drawing of the constellation of Cetus and others with scales.
This appears to record observations of the variable star Mira of Cetus between 10 and 18 March of an unknown year. The text records that it was 'Drawn from the french Padres draft', which may suggest that this was copied from the papers of Ismael Bullialdus, a French mathematician and Catholic priest who reported on this star in Ad astronomos monita duo (1667). This work was reported in 'Philosophical Transactions' vol. 1, no. 21 (1667).
