strong jets through the safety tube. It is therefore advisable to 
treat the oxalate with nitrate of baryta or chlorid of barium, 
leaving them in contact for a day, to evaporate the filtrate and 
then distill. I give the preference to the nitrate of baryta, be- 
cause the nitrates of the ammonias distill more quietly than any 
of the others of these salts. 
The methylamine thus obtained was converted into chloro- 
platinate and analyzed.*
