Nurunacrina Séma Sta bears the meaning in Sanscrita of the Malabar 
terms * Purnamana Soma Yagi,” the first word being the name of his house. 
The last verse of his work contains its date in numerical letters in terms 
of days of the Caliyuga ; a mode of dating which, in the country, is to be 
traced back to upwards of one thousand seven hundred years ago, as may 
be seen in the inscriptions taken from the pagoda of Tirwvunnir near 
Calicut. The verse is as follows: 
Iti sivapura nam agramajah Capiyajwa 
Cimapi Carana padhatyahwayam tantra rupam 
Vyadhita ganita metutsamyagalocyasantah 
Cathitamihavidantassuntu santosha pantah. 
The words Ganita Metutsamyac, written in numbers, amount to 1765653 in terms 
of days of the present age; which is found to agree with A.D. 1733, being 86 years 
and 271 days before the 3lst of December 1819; Sdéma Yast was not, however, 
inventor of the system by which he formed his infinite series. 
The author of the Tantra Sangraha, who was educated in the college of 
Bréhmanas at Trichtr (which college still exists, and which is a place of 
reputed sanctity, and certainly of respectable learning), has, among his works 
on arithmetic and astronomy, laid the foundation for a complete system of 
fluxions, and opened a mine of wealth in mathematics to those students 
who can boast of being his followers, of which they are most eminently 
jealous. The copy of the work, which I have obtained with some difficulty, 
by frequent intercourse with this interesting society, bears in itself marks 
of antiquity, the commentary in the vulgar tongue being written in a 
language which is not now generally current in Malabar, and the forms of 
many letters differing materially from those of the present day. 
The author of the work is TaracutatrOra Namsu Tir, of Cérala, or 
Malabar ; the first epithet being the name of his house, the latter the title 
of his rank: he flourished in the forty-sixth century of the present age, or 
Caliyuga. 
The testimonies as to the author, and the period in which he lived, are 
the following, viz. The general consent of the learned in Malabar; the 
date which is shewn in the commencement of the work itself, namely, the 
year 4600 of the Caliyuga ; the mention made of him in the first chapter 
of a work named Driccaranam by his commentator, the author of the 
Yucti-Bhdashad, Cettatura Namsutirt, in which, while relating the history 
of the progress of astronomy, from the improvements of A’ryAB’HATTA up
