The six grains which were insoluble in water, were treated for
forty-eight hours with alcohol of the specific gravity ·817, at 66°
of Fahrenheit; a green solution was obtained, but by slow
evaporation only _half a grain_ of solid green matter was procured.
The insoluble residue obstinately adhered to, and coated the filtre
like a varnish, and completely defended the mass from the action of
the alcohol; it is probable that it consisted principally of
_Starch_.
