 sively about Pisces and Aries, in the time that the index 

 goes over two hours. Therefore, whilst the moon is in 

 Pisces and Aries, she will not differ in general above two 

 hours in her rising for a whole week. But if you take 

 notice of the marks on the opposite signs, Virgo and 

 Libra, you will find that seven of them take nine hours 

 to rise ; which shews, that when the moon is in these 

 two signs, she differs nine hours in her rising within the 

 compass of a week. And so much later as every mark 

 is of rising than the one that rose next before it, so 

 much later will the moon be of rising on any day than 

 she was on the day before, in the corresponding part 

 of the heaven. The marks about Cancer and Capricorn 

 rise at a mean difference of time between those about 

 Aries and Libra. 



Now, although the moon is in Pisces and Aries every 

 month, and therefore must rise in those signs within the 

 space of two hours later for a whole week, or only about 

 seventeen minutes later every day than she did on the 

 former ; yet she is never full in these signs, but in our 

 autumnal months, August and September, when the sun 

 is in Virgo and Libra. Therefore, no full moon in the 

 year will continue to rise so near the time of sun -set 

 for a week or so, as these two full moons do, which fall 

 in the time of harvest. 



In the winter months, the moon is in Pisces and 

 Aries about her first quarter : and as these signs rise 

 about noon in winter, the moon's rising in them passes 

 unobserved. In the spring months, the moon changes 

 in these signs, and consequently rises at the same time 

 with the sun ; so that it is impossible to see her at that 

 time. In the summer months she is in these signs about 

 her third quarter, and rises not until midnight, when 

 her rising is but very little taken notice of; especially 

 as she is on the decrease. But in the harvest months she 

 is at the full, when in these signs, and being opposite to
