in the Makaranda, and from these the figures given by us for every 1/100th of a circle, or 10 units of the argument of the Tables, are easily deduced.
110. The use of the auxiliary Table is fully explained on the Table itself.
111. Table VIII. This is designed for use with our method C, the rules for which are given in Arts. 139—160. As regards the tithi-index, see Art. 80. The period of a nakshatra or yoga is the 27th part of a circle, that is 13° 20′ or 10000/27 = 370+10/27. Thus, the index for the ending point of the first nakshatra or yoga is 370 and so on.[1] Tables VIII.A. and VIII.B. speak for themselves. They have been inserted for convenience of reference.
112. Table IX. is used in both methods B and C. See the rules for work.
113. Table X. (See the rules for work by method C.) The mean values in solar time of the several elements noted herein, as calculated by the Sûrya-Siddhânta, are as follow:—
| A tithi | = | 1417.46822 | minutes. |
| A lunation | = | 42524.046642 | minutes.do. |
| A sidereal month | = | 39343.21 | minutes.do. |
| A yoga-chakra | = | 36605.116 | minutes.do. |
From these values the time-equivalents noted in this Table[2] have been calculated. (See also note to Art. 82.)
114. Table XI. This Table enables calculations to be made for observations at different places in India. (See Art. 36, and the rules for working by our method C.)
115. Table XII. We here give the names and numbers of the samvatsaras, or years of the sixty-year cycle of Jupiter, with those of the twelve-year cycle corresponding thereto. (See the description of these cycles given above, Arts. 53 to 63.)
116. Table XIII. This Table was furnished by Dr. Burgess and is designed to enable the week-day corresponding to any European date to be ascertained. It explains itself. Results of calculations made by all our methods may be tested and verified by the use of this Table.
117. Tables XIV. and XV. are for use by our method A (see the rules), and were invented and prepared by Mr. T. Lakshmiah Naidu of Madras.
Table XVI. is explained in Part V.
118. The Tables now published may be used for several purposes, of which some are enumerated below.
(1) For finding the year and month of the Christian or any Indian era corresponding to a given year and month in any of the eras under consideration.
