90 PROFESSOR HEDDLE ON THE MINERALOGY OF SCOTLAND. 
1. The analysis of the following specimen, however, goes a long way to 
establish the specific individuality of Mr HarpMan’s mineral. 
In the basaltic pillars embedded in the tufa of the Spindle at Kinkell, in 
Fifeshire, there very rarely occurs, filling small druses, a dark-green almost 
black mineral, which has in certain lights a slight brownish tint. It has a very 
minute granular structure, is dull, but the impression of the nail leaves a 
polished streak, It is very soft. 
It is occasionally pseudo after analcime, and its associates are analcime, 
augite, and black lustrous titaniferous iron in angular fragments. 
It was conceived to be possibly one of the substances called ‘“ chloropheite 
from Fife” by Dr Maccuttocu, and was considered to be Delessite.

It lost 8:039 of the above water at 212°. It was readily decomposed by 
acids. 
It was found to contain ferrous oxide, but there was not enough material 
for the determination of its amount. While this non-determination of the 
ferrous oxide leaves its composition in doubt, the claim of Hullite to rank as 
a species is considerably fortified by the circumstance of the analysis of this 
specimen having been performed so speedily after its extraction from the rock 
that there was no reason to believe that any more than a merely trifling 
loss of water had occurred. 
It at the same time was so uniform in structure that it could not be 
regarded as a mixture, and its composition does not permit of its being ranked 
with either Delessite or chloropheite.
