about 15 times its bulk of water.» The voluminous floccu-’ 
lent precipitate was immediately filtered, washed, the last 
time with hot water, and dried with care. The powder thus 
obtained is of a light yellow color and slightly bitterish 
taste. It is insoluble in water, dilute acids or alcohol but 
soluble in dilute alkalies: On heating these solutions a 
decomposition sets in and new products are formed, which 
the author has not yet analysed. On heating the powder in 
a dry test tube it behaves like the original Albumen. »

The rational name of this compound is: “ Hexanitroalbumin 
sulphonic acid.” 
When this new pay is treated aah Sulphide of Ammo- 
nium, a new amorphous body is obtained, which bears re- 
semblance neither to Albumen nor to Albuminsulphonice acid. 
This last new body seems to combine with acids as well. as 
with bases. The author intends making further investiga- 
tions on this point. 
The author obtained another derivative i ee Albumen 
with concentrated Sulphuric acid. In a mortar was mixed
