What is the meaning of long-term and middle-term relationships?
Comment: See the book on page 22, first sentence, where long-term planetary relationships are defined as Jupiter-Pluto through Neptune-Pluto (the last 10 relationships in the right column). All planetary relationships that are not long-term are therefore middle-term by Bradley’s definition since he only mentioned long-term (L) and middle-term (M) in his equation on page 35. Therefore, the lower curve on our siderograph is the summation of the middle-terms for all the relationships in the left column of page 22 plus the eight top-most in the right column.
