Put the materials into a deep and wide silver pan, and make them boil, eva¬ 
porate, continually stirring, and taking care to regulate the fire towards the 
end, until the mixture is reduced to a very thick consistence, detach this and 
divide it, drying upon plates; break up the dry product and keep it in well- 
stoppered bottles 
Soluble cream of tartar is in amorphous, transparent pieces, with an acid 
flavour ; it should dissolve entirely in water. This preparation is not in the 
P. B., it can be made to scale in very pretty thin transparent scales of a glossy 
appearance.

This is an obsolete steel wine, made with cream of tartar, steel filings, water, 
and alcohol. ' 
152. Boules de Mars*. 
Boules de Nancy, Globuli Martiales. 
Martial Balls. 
This appears to be one of the extraordinary preparations of the Codex, and 
if not led to think it was a favourite upon the Continent, one would imagine 
it was introduced as a curiosity. 
The boules de Mars are prepared with steel filings, crude tartar, water, and 
especes vulneraires, the especes vulneraires comprising the leaves and tops of 
seventeen and the flowers of three plants, making altogether twenty different 
plants. 
The process is tedious and troublesome, occupying from two to three months, 
and the preparation when finished about as elegant and useful as the mistura 
ferri aromatica of the P. B. 1867.
