noted appears to be about 200 years old and work itself may be roughly assigned to the middle of the 17th century.

The classification adopted is a development from that of piÅ’kalantai, There are 56 sections and of these, the last seven deal with homonyms. Theother sections relate to class-vocabularies and contain about 15,000 names.

NAMATIPA -NIKANTU.

Another work whichstrikes out a new scheme of classification is Nƒmatipa- nika--u Its author was Subrahma-ya Kavirƒyar of Kallidai-k-kuŠicci, son of the scholar who wrote Potikai-nika--u. p‡vai-p-purƒ-am, by the sameauthor, was composed, as already mentioned, in 1810 A.D. In Nƒmatipa- nika--u, the grammatical classificationinto uyar-ti-ai and ƒˆŠi-ai isadopted with suitable sub-divisions; and a chapter on 'qualities' is added at the end.The details of thescheme are set forth in the eight verses forming the introduction. There are 16 sections containing 800 stanzas in ve-pƒ metre. About 12,000 are treated.

TOKAI-NIKANTU

Before we pass on to works dealing solely with homonyms, we may mention a particular kind of nika--u known as nika--uPal-oiry--k‡--attoru-peyar-t-tokuti. Subordinatespecies of the technical and generalterms of science and literature', in Beschi's words, forms its subject-matter. Things are grouped in various numerical aggregated and these group-names areexplained in the numerical order. Tivƒkaram andsimilar works treated of these groups in their final sections, In course of time, separate works on this subject began to appear. Tokai-nika--u1, by Subrahma-ya Kavirƒyar, is a work of this kind . The manuscript of this has not yet been traced and our knowledge of it is obtained only from the introductory verses of the author's. Nƒmatipa- nika--u.

PORUTTOKAI-NIKANTU

Poru--okai- nika--u. is another work dealing with group-names. Its author was Subrahma-ya Bhƒrati, šon of Vaitt…swara D…k™itra of Ku-umiyƒmalai.Its data is date is unknown. It has been published by the Madura Tamil Sangam and Mr.R.Subrahmanya Kavirƒyar, Its editor, has added 122 sutras of his own, brining the total number to 1,000.

TOKAI-P-PEYAR-VILAKKAM

Another work of thisclass is Tokai-p-peyar-viËœakkam of Mudaliyar, published in 1840. in this, the groupnames under each numeral are arranged alphabetically.

ILAKKA-T-TIRAVUKOL

Several decades after, appeared another small Ilakka-t-tiŠavuk†l2. Its special feature is that all the group-names are given in one alphabetical list, without being arranged under different numerals. We have been till now considering class-vocabularies which correspond to the modern 'thesaurus', and group-names. There came into existence.
