To find the Cuspe of the 11 house.
- Unto the Right Ascension of the 10 house
- 72. 82173
- Adde 30 degrees
- 30. 00000
- And then the oblique Ascension of the 11 house
- 102. 82173
- To this adde
- 30.
- Oblique Ascension of the 12 house
- 132. 82173
- 30.
- Oblique Ascension of the Ascendant
- 162. 82173
- 30.
- Oblique Ascension of the 2 house
- 192. 82173
- 30.
- Oblique Ascension of the 3 house
- 222. 82173
The Oblique Ascension of the houses thus found by a continuall additi∣on of 30 degrees, we must next find the poles elevation upon their severall circles of position thus, In the rectangle sphericall Triangles E A B and E C D we have limited. 1. Their common angle at E the latitude of the place. 2. E B and E D 38 and 60 with the right angles A and C to find the angles B and D, being the angles that the circles of position make with the Equator.
