16. Doc-rooTH SPAR.

In basalt. Similar to No. 12. 
16a. CALCITE. 
Geelong. 
Light yellow, acute rhombohedrons, 
coating limestone. 
17. FRESHWATER LIMESTONE. 
Map No. Ra 1. 
Muchleford Creek, lot 4, section 4, 
Strangways. } sheet 15 N.E. 
Containing cavities filled with fine 
crystals of “arragonite” and “ calcite.” 
The former are especially characterized 
by fine terminal planes, which are seldom 
found on those occurring in the basalt. 
17a. CARBONATE OF LIME.

Mammillary coatings of cavities in 
the basalt.

Coating “hyalite” in mammillited 
crusts, filling cavities in the basalt, 
19. Catc-Spar. 
Phillip Island, Western Port Bay. 
In older basalt. ` 
20, LIMESTONE. 
Section 46, Redesdale. 
13 N.E. 
Occurs in lumps and horizontal veins, 
in a red-and-yellow mottled clay, full of 
ironstone pebbles, under 8 feet of basalt, 
and overlying grey, cellular basalt. It 
_ is nearly pure, and burns and slakes 
well, but is not abyndant,

Map No. M 41. 
Stone-jug Oreek, Spring Plains. 
} sheet 13 N.E. 
Occurs, underlying the basalt, in a bed 
a few inches thick, formed apparently 
by infiltration or absorption of carbonate 
of lime into the vegetable tissue of a 
moss, and the subsequent decomposition 
of the moss leaving the carbonate of lime 
in its exact form. Itis a beautiful object 
under a strong magnifying power.

4 sheet 9 N.E. 
Occurs in cakes from 1 to 2 feet thick; 
overlying a porphyritic dyke (in the bed 
and banks of a tributary of the Cam- 
paspe), from the joints of which bubbles 
of carbonic acid gas are constanly rising.

25. MacnesitE (Carbonate of 
Magnesia). List No. Mu 10. 
Lot 7, parish of Tarrangower,near 
Loddon River. 
Occurs in nodular masses in surface 
drift. These nodules, on analysis, are 
found, not to consist of pure carbonate 
of magnesia, but to contain small and 
variable quantities of the carbonates of 
lime and iron, with alittle clayey matter. 
Magnesite has lately been profitably 
employed by the “aerated bread? com- 
panies, for the production of pure car- 
bonic acid. gas, and is likewise in 
demand for the manufacture of “fluid, 
magnesia.”
