thole of the wit,, but bigger. 
3. That afterwards continuing the Obfervations , he found 
the Spots of thefe two Faces to turn by little and little from 
Eaft to Wefts and to return at laft to the fame fituation, wherein 
he had feen them firft. 
4. That S, Campani, having alfo obferv’d at Form with Glaffes 
of 50 .Palmes or about 3 7 To^likewife of his own contrivance,

7. That the Spots return the next day to the fame fituation, 
40.minuts Liter.than the day before; fo that in every 36. or 37. 
daies, about the lame hour, they come again to the fame place, 
8. He promifes fhortly to give us the particular Tables oi this

themfelves. 
9. Pie reprefents,that fome other Ajlronomers have alfo made 
at Rome feveral Obfervations of thefe Spots of Mars , from 
March ~ to March jk with Glades, wrought by Euflaehio Di -

Mars to be performed, not in 34 h/40 m. (as he maintains it is) 
but in about ig h. 
11. And to evince, that they aremiftaken in thefe Obferva-
