and a Body of a similar nature existing in Oats. 23 
ble. The oats were of common varieties, ground tolerably fine. 
Oat meal was first tried, but the kiln drying of the grain prepara- 
to a separation of the husk, seemed to have changed the solu- 
bility of the protein body. In my former remarks upon the prop- 
erties of this body, I said that it was largely soluble in cold water. 
On a second examination this did not appear to be the case, and 
repeated experiments satisfied me that the large quantity obtained 
formerly arose from the addition of a drop or two of ammonia in 
order to prevent the liquid from souring, it being very warm 
weather at the time. 
_ There is, however, in the oat a substance, which though in 
small quantity, is readily soluble in cold water. It is precipita- 
ted by dilute hydrochloric or acetic acids, but not instantly, it 
falls slowly, and in a state of minute division. 
- Nothing is precipitated at first upon boiling the solution, but a 
small quantity appears after cooling. 
It is partially dissolved in an excess of acetic or hydrochloric 
acid ; entirely on the application of heat. 
_ It dissolves readily in an excess of ammonia. 
_ It is precipitated in considerable quantity by both the neutral 
and basic acetates of lead. 
- The legumin of almonds, is extremely soluble in cold water, 
and in very large quantity. On the addition of a single drop of 
hydrochloric or acetic acids, a most abundant precipitate falls at 
once and in large flocks. When the solution is boiled, a very 
considerable precipitate falls almost instantly. 
- It partially redissolves in an excess of acetic or hydrochloric 
acid, entirely when heat is applied. ms 2, 
It dissolves in an excess of ammonia, and is precipitated in 
quantity by both the basic and neutral acetates of lead. 
_ The legumin of peas, is equally soluble in cold water, and 
also in very large quantity. Like the above, it falls instantly 
and in large flocks on the addition of very dilute acetic or hydro- 
eae acids. : :

_ The addition of a neutral or basic acetate of lead does not 
cause a large precipitate, but merely renders the solution cloudy.
