quantities of magnetite, quartz and calcite. Besides these 
constituents there are, just as in the skarn from many other 
localities, considerable amounts of epidote. For the analysis 
purest possible chips where selected by hand, crushed up 
and digested with strong hydrofluoric acid which dissolves 
the other constituents easier than the garnet. Some quantity 
of quartz, however, remained undissolved and to this is 
apparently due the little excess in SiO, over the garnet ratio 
shown by the analysis. The result was as follows:

In the following we quote the analysis of the garnet 
"from the sviatonossite once more (I), to be compared with 
the analysis of the garnet from the skarn from Sviatoy Noss 
(II), and a few other analyses of the andradite from skarn- 
rocks: III is the analysis of the andradite from Orijärvi 2). :' 
Analysis IV, made by M. Dittrich, represents a dark green 
andradite from Grua, Christiania Region ?), analysis V, also 
by Dittrich, is one of an andradite from El Carmen, Con- 
cepeiöon del Oro, Mexico 3) and analysis VI gives the composi- 
tion of the garnet fron Kamaishi, Japan ?).
