Extract

1. When a peat, as obtained from the bog, is dried, considerable changes occur in the amount of ammoniacal nitrogen removable by distillation with magnesia under reduced pressure.

2. Removal of water causes a relative increase in the amount of ammonia extractable by water. This is due to a reduction in the absorptive colloidal properties of the peat.

3. A partial recovery in the absorptive power takes place on prolonged contact with water.
