T wave already introduced a subject from the skies, and it 
is not a little remarkable that it should be necessary to do 
so again, but to show the insulated crystal of Water I have 
no other resource. Indeed Water in any form may be 
deemed more absurd in British Mineralogy than the Me- 
teoric Stone. As it, however, belongs neither to the 
Vegetable nor Animal Kingdoms of Nature, it must remain 
to the Mineral one, and this with the more propriety as its 
ingredients are found dispersed in that division. It has 
long been known that 85 parts of Oxygen Gas and 15 parts 
of Hydrogen Gas, combining at the expense of the greater 
part of their Calor, or the Galvanic or Electric Fluids, &c. 
form Water, and that this becomes solid, or Ice, at 32° of 
temperature, being liquid above that point. Hence it is 
mostly in the latter form that it is best known, such being 
the more usual temperature of the atmosphere, especially 
in moderate climates: in winter indeed it is often in the
