HIPPARCHUS (150 B.C.) was the first in Europe to prepare a catalogue of stars showing their longitudes and latitudes after taking necessary observations. It is not at present available; but PTOLEMY after making allowance for ayana motion, prepared another catalogue (138 B.C.). It is at present available in his work entitled Syntaxis. It contains 1022 stars, grouped into 48 constellations. A second Catalogue after this, was prepared by 'ULUĞ BEY, grandson of Tamerlane, and Emperor of Samarkand in 1437 A.D. It contains 1019 stars. Another catalogue containing 777 stars was prepared by TYCHO BRAHE, in 1600 A.D. Afterwards, several catalogues were prepared in Europe. No one in our country appears to have prepared such a catalogue by taking actual observations. MAHENDRASŪRI has, in his work Yantrarāja, given polar longitudes and latitudes of 32 stars from the works of Greeks. Malayendu Sūri, the commentator of that work observes,”
