2. On hydrorylamine.—Lossen has succeeded in replacing an atom 
med drogen in ammonia by an atom of peroxyd of hydrogen or hydroxyl.

short time, but not much hydrogen is evolved. When the action is over 
evaporation ; larg antities of salammoniac first crystallize out, and 
afterward the chlorhydrate of hydroxylamine, which is very easily soluble 
in water, is may be completely separated from salammoniac by dis- 
NHO,+6H=NH,0+2H,0. 
The chlorhydrate of hydroxylamine crystallizes from a hot saturated solu- 
ton in aleohol in needles or in broad leaves; its formula is NH,@. HCl. 
@ sulphate has the formula 2NH,@.H,S@,. The nitrate could not 
,odtained crystallized; the oxalate crystallizes in beautiful prisms 
Which have the formula 2NH,0.€,H,©,. It is not yet decided 
Whether hydroxylamine can be prepared pure in the isolated state. 
When a concentrated solution of a salt of this base is treated with 
caustic potash, nitrogen is given off rapidly and ammonia is formed. 
The decomposition may be represented by the equation 
3NH,O0=NH,+2N-+3H,9. 
Tn dilute solutions the decomposition takes place gradually. When 
sulphate of hydroxylamine is precipitated by baryta water a more stable
