We will suppose, a— rate of motion of Vernal Equinox when it coincided with the star Kevati. the annual increment in tlie rate. Z= the last term or rate of motion on the first January 18e3. ' sz=i the sum of the terms or the length of the Ayanamsam. n = number of terms or number of years required. We have the following series: a, a + d, a ■{-2d, a 4-3d, ai-{n—l)d.

Substituting these values, we get n= 14,66 and 4,17,368 years , or = 1310 and 4,17,523 years, before first January 1883 where the bigger figures may be rejected as they refer to the position of the vernal Equinox in its second revolution. 8o that Varaha Mihira^s time is found to be eitherl882-l466= 416 A.

But I cannot bring myself to believe that Zeeta piscium was the Kevati of the Hindus, for this sim- ple reasonAhat it is not on the ecliptic. Several st'nrs of compa-
