in wliich he shows that the most important agent in producing the 

 flavouring of tea is an enzyme, and that this materially increases 

 during the process of withering, while the largest amount is found 

 in the tip leaves, which make the best tea, and that the amount of 

 phospates in the soil increases the amount of enzyme and the quality of 

 the tea ; all highly important points. Another very interesting paper in 

 this section is one on Tidal periodicity in the Earthquakes of Assam by 

 Mr. R. D. Oldham, Superintendent, Geological Survey of India, in 

 which he considers the effect of the tidal stresses set up by the attrac- 

 tion of the san on the time of occurrence of earthquakes recorded in 

 Assam since the great one of 1897, and he concludes that there is such a 

 relationship. 



Altogether the year has been a good one in this section, both the 

 number and the variety of the papers having maintained a high level. 



Journal, Part III. 



In all, three numbers of this part of the Journal, containing ten 

 papers, were issued during the year, viz. : No. 2 for 1901, and Nos. 1 and 

 2 for 1902. The first of these numbers contains a paper by Mr. T. H. 

 Holland, F.G.S., on the Coorgs and Yeruvas, in which the affinities 

 of the two tribes are discussed on an anthropometrical basis. Apart 

 from the fact that the Coorgs are shown to differ ina very marked degree 

 from their Dravidian neighbours, this paper contains an interesting 

 discussion on the manner of applying in practice the results obtained 

 from anthropometry. 



Amongst other papers may be mentioned Mr. Friend-Pereira's 

 account of the " Marriage Customs of the Khonds," the " Folklore of the 

 Kollian," by Mr. C. H. Bompas, I C.S., and " Some Notes on the Rajvamci 

 Caste" by Babu Monmohan Roy. The last mentioned, paper offers an 

 explanation of the divergent views that have been expressed regarding 

 the origin of the Rajvarocis of North Bengal and of the Koch and other 

 tiibes in their neighbourhood. It appears that the original Raj vain ci 

 was a Dravidian, but that the term has also been assumed by the Mongo- 

 loid Koch, and that in some parts the'assumption of the name has been ac- 

 companied by intermarriage between the two groups. It has recently 

 been arranged to add a supplement to this part of the Journal for the 

 publication of miscellaneous notes on anthropological subjects.
