Note 20 — Chapter XI · Disease.

The astrological origin of the evils ascribed to the Yakseyo (Demons) of Ceylon, and the horoscope which is a necessary preliminary to any dealing with their influences; the constant recurrence of the number seven, denoting origin with races holding the seven-planet theories of the universe; and the fact that all demons are said, on every Saturday evening, to attend an assemblage called Yaksa Sabawa (Witches’ Sabbath), are facts that may well engage the attention of Comparative Mythologists.20 In Dardistan the evil spirits are called Yatsh; they dwell ‘in the regions of snow,’ and the overthrow of their reign over the country is celebrated at the new moon of Daykio, the month preceding winter.
