The quotient represents complete karctncts. ^ What remains after the division is multiplied by 60, and divided by the bhuktyctntctra. The quotient re¬ presents how much has elapsed of the current karctnct. Every unit of the number is equal to half a ghctti. We now return to the complete kctrctncts. If they are two or less, you are in the second kctranct. In that case you add one to the number and count the sum off, beginning with catushpctdct. If the number of kctrctncts is 59, you are in sctkuni. If it is less than 59 and more than two, add one to them and divide the sum by seven. The remainder, if it is not more than seven, count off, beginning with the beginning of the cycle of the movctble kctrctncts, i.e. with bavct. Thereby you will arrive at the name of the current kctranct in which you happen to be. The karanas Wishing to remind the reader of something relating as borrowed . byAikindi to the kctrctuas which he perhaps has forgotten, we Aiab must tell him that Alkindi and others like him have hit upon the system of the karctncts, but one which was not sufficiently explained. They did not comprehend the method of those who use the karancts. At one time they trace them back to Indian, another time to Babylonian origin, declaring all the time that they are altered on purpose and corrupted by the inadvertence of the copyists. They have invented a calculation for them which proceeds in a better order than even the original method itself. But thereby the thing has become something totally different from what it origi¬ nally was. Their method is this : they count half days, beginning with new; moon. The first twelve hours they regard as belonging to the sun, as burning,i.e. unlucky, the next twelve hours as belonging to Venus, thi authors. ```
