places as at Mellialum is auriferous — it is from the decomposition of 

 this into soil that the gold is procured. Gold was discovered in the 

 eastern provinces of Mysore by Lieutenant Warren of H. M. 33d regi- 

 ment in 1802 — he found it in the small nullahs, or ruts, or breaks, in the 

 ground, at Warrigum, a small village 4| miles S. W. of Battamungalum 

 • — also on the banks of the Palar river, and the Ponian, near Caargory — 

 from a load of this earth near the last, he obtained three sparkles of 

 gold. He found gold also at Marcoopium 3 miles south of Warrignm — 

 here there were mines worked by the natives. Tippoo had worked 

 them also, but desisted on finding that the produce just balanced the 

 expences. The strata described by Lieutenant Warren as existing in 

 the different mines do not agree, but the ore was found in large stones, 

 of a siliceous or quartzy nature, of a black changing to deep rust colour, 

 to which generally adhered a deep orange soft substance. Within the 

 golden tract the proportion generally obtained by him was one grain of 

 native gold out of 12 baskets of earth taken at random. 



Corundum is found at Mundiura near Seringapatam, and in other parts 

 of Mysore, as at Tippity Beygoor, three days march from Bangalore, and 

 Bunercottah, about 12 miles from Beygoor, 9 miles from Bangalore — ■ 

 it is of different colours grey, blue and reddish. Rubies of a 

 coarse kind have been brought me ; and also heryJ, or what Dr. Heyne 

 calls the schorlous beryl.

TW/c Sltbjects 01 Doxinii/^-\l. inquiry, both of considerable interest, have 

 recently engaged my attention ; and as the conclusions at which I have 

 arrived are somewhat different from what I anticipated at the out-set, I 

 think a summary of the results may not be uninteresting to your botani- 

 cal readers. The first of these, taking them np in chronological order, 

 was the examination, for my Illustrations of Indian Botany, of the natu- 

 ral order Guttiferae for the purpose of marking out its limits and eluci- 

 dating its Indian genera and species. The second was an endeavour to 

 ascertain the Laurus Cassia of Linnseus, and the tree which furnishes the 

 Cassia bark, or Cassia Ugnea, of commerce ; undertaken by order of 

 Government, with a view to the solution of a question submitted for it^
