VICTORIAN METEORITES, WITH NOTES ON OBSIDIANITES. 
as were found in the Cranbourne No. 2 between the nickel -iron 
plates, were noticed, although this fact might easily be accounted 
for by the small amount of material examined. The taenite lamellae 
showed, in a similar manner to those of the Cranbourne No. 2, the 
crystals referred to schreibersite. Generally, the mineral, however, 
was not plentiful as in the Cranbourne No. 2 meteorite, it seemingly 
having been replaced by cohenite. 
Rhabdite. — This mineral permeates the iron in fine prismatic 
crystals and differs in no way from its mode of occurrence in the 
Cranbourne No. 2, except that it was not nearly so plentiful. 
In the Cranbourne No. 1 and the Beaconsfield meteorites the mineral 
apparently also shows no divergence in its form and manner of 
disposal. Similarly, as in the Cranbourne No. 2, fine prismatic 
crystals occur on the taenite lamellae which can, in all probability, 
be correctly referred to rhabdite. 
Cohenite. — In the residues after solution of the nickel-iron in 
dilute hydrochloric acid, a quantity of brittle, coarse, slightly 
porous powder remained behind with the taenite, schreibersite, 
and rhabdite, and, being tarnished, it imparted a much darker 
appearance to the residues than was noticed in those from the Cran- 
bourne No. 2 ; so much so, that it afforded an easy means of distinction 
between the two. This fact led to an examination being made for 
cohenite on similar lines to those made for it in the residues from the 
meteorite just mentioned. Some of the grains were dissolved in 
aqua regia and tested for phosphoric acid with negative results. 
Solid carbon particles were obtained by treatment with copper- 
ammonium chloride, which burned with deflagration on ignition. 
In the section of the meteorite no crystals were seen such 
as could be referred to cohenite. A group of small irregularly 
oval patches occurred, however, on one part of it, having the 
characters common to that mineral and schreibersite. They 
were granular and broke up during treatment into a powder. 
Judging by the abundance of cohenite in the residue compared 
with schreibersite it is very probable that the patches in question 
consisted of the former mineral.

The analysis was made on material left as a residue after treat- 
ment of some powdered crust with dilute hydrochloric acid. It
