Xos. 1 and 2 = spessartite ; from gondite series. Centra! Provinces. 
Nos. 3 and 4 = spandite ; from kodurite series, Vizagapatam 
No- 5 = manganese-grandite ; from kodurite series, Ganjam. 
Nos. 1 and 3 are from actual analyses of garnets, and Nos. 2, 4 and 5 calculated from 
=inalyses of rocks containing them. 
We can now consider the Indian manganese-garnets under the head- 
ings ol spessartite, spandite, grandite, aplome and calderite. 
Spessartite. 
On the strength of two analyses, I am, as explained above, pro- 
visionally calUng all the garnets found in the gondite 
Occurrence of spes- series, i.e., in the manganese-bearing rocks of the 
Central Provinces, Jhabua, and Narukot, by the 
*Calculated.
