278 ARABIC AND INDIAN DIVISIONS OF THE ZODIAC third, also in the head of the Ram, the asterism is denominated Āshrait. The bright star of the second or third magnitude which is out of the figure of the Ram, according to Ulugh Beg, but on the nose according to Hipparchus, cited by this author from Ptolemy, is determined Nātih : It is placed in lat. 9°30'N and long. 1 0° 43', and is apparently the same with the principal star of the Indian asterism; for Muhammad of Tizin, in his table of declination and right ascension, expressly terms it the first star of the Sheratain. 2. Bharaṇī, the second asterism, comprises three stars (35, 39, 41 Aries) figured by the yoni or pudendum muliebre and the principal and southern star of this nakṣatra is placed in 12°N. On the Arabian system, the second manzil, entitled Butain is placed by Ulugh Beg in lat. 1°12' and 3°12', and this cannot possibly be reconciled with the Indian constellation. But Muhammad of Tizin assigns to the bright star of Butain a decli- nation of 23°N exceeding by nearly 2° the declination allotted by him to Nātih or his first star in Sheratain. This agrees with the difference between the principal stars of Aśvinī and Bharaṇī; and it may be inferred, that some among the Mohammadan astrono- mers have concurred with the Hindus in referring the second constellation to stars that form Musca. 3. Kṛttikā, now the third, formerly the first, nakṣatra consists of six stars figured as knife or razor, and the principal and southern star is placed in 4½ or 5°N and in 65 sixths of degrees (or 10°50′) from its own commencement (cf. the Sūryasid- dhānta), or 37° 28′ to 38° from the beginning of the Meṣa (the Siddhānta-Śiromaṇi or the Graha Lāghava) respectively. This longitude of the circle of declination corresponds nearly with that of the bright star in the Pleiades, which is 40° of longitude distant from the principal star of Revatī. The stars indicated by Ulugh Beg for Thurayyā, also corres- pond exactly with the Pleiades. 4. Rohiṇī, is the fourth nakṣatra, the Arabic name for the fourth mansion is Debarān (or with the article Aldebarān). It corresponds to the bright star called the Bull's eye, and which is unquestionably the same with the principal and eastern star of Rohiṇī, placed in 4½° or 5°S and 49½°E by the Hindu writers on Astronomy. This nakṣatra is
