SYNOPSIS OF PART I. 
Chemical analysis shows the mineral to be allied to both tremolite 
and richterite. It is found in schistose rocks at Kajlidongri and is of 
metamorphic origin. 
Juddite. — The chief diagnostic of this mineral is the following 
beautiful pleochroism : — 
a = carmine, 
b = blue with a lilac tinge, to pale green with a Jilac tinge, 
c= orange. 
It is found with blanfordite in a braunite-albite rock at Kacharwahi, 
and is probably of igneous origin. It is further distinguished as being 
one of the rare amphiboles with the optic axial plane at right angles 
to the plane of symmetry of the mineral, instead of coinciding with 
it.

Silicates : Garnets. 
Mamjaneae-garnds are very abundant in some of the Indian 
manganese-ore deposits. The varieties found in the Central Provinces 
are grouped under the name spessartite, and the series of rocks in 
which they occur, which is of metamorphic origin, is called the gondite 
series. Many good crystals of this spessartite have been found and 
eight examples are figured. The chief form is the trapezohedron. The 
locaHties for the best crystals are Jothvild, Hatora, Bichua, Gaimukh, 
Chargaon, Satak, Waregaon, and Kulu, all except the first and last 
being in the Central Provinces. 
Spandite. — The garnets found in the kodurite series — of igneous 
origin — in the Vizagapatam district, Madras, are found to be roughly 
intermediate between spessartite and andradite in composition. For 
convenience of use they have therefore been designated spandite, a con- 
traction of spessart- andradite. Spandite has not yet been found exhibi- 
ting definite crystal faces, being always in more or less romided gran- 
ules. 
Grandite.—^ocks, of the kodurite series seem also to occui at 
Boirani in the Ganjam district of Madras. But the garnet is found 
to dift'er in composition from that of Vizagapatam and to be a
