oxalate of ammonia is poured into a solution of tribasic acetate of 

 lead ; but in this case it is pulverulent, and devoid of lustre. 



In ■whichsoever mode prepared this salt absorbs carbonic acid from 

 the air, and is eventually converted into a mixture of carbonate and 

 neutral oxalate. Nitrate of lead boiled with this salt is rapidly 

 changed into neutral oxalate, whilst the nitrate becomes bibasic. 

 Nitrate of lead, slightly heated "with carbonate of lead and water, be- 

 comes raonohydrated bibasic nitrate ; there occurs, during the change, 

 so rapid and abundant a disengagement of carbonic acid, that it might 

 be supposed free nitric acid was present in the solution. — Journal de
