chloric acid solution from this second lot of 10 gms. yielded 
a precipitate with hydrogen sulphide weighing °*0316 gm., 
this was ignited and ground in an agate mortar and yielded 
streaks of a white metal, which disappeared on treatment 
with nitric acid. 
In a third experiment 100 gms. of the sawdust from slice 
No. 6 were treated with hydrochloric acid, and the insoluble 
residue treated as before. A-few specks of yellow metal 
insoluble in nitric acid were left, these were again evapor- 
ated down to dryness with nitric acid and remained undis- 
solved, so that they appear to be gold. 
One hundred gms. of planings from slice No. 7 were 
treated with pure sulphuric acid, the acid was previously 
treated with hydrogen sulphide to remove any platinum 
which might have been present; the insoluble residue 
amounted to 2°7952 gms.; neither gold nor platinum metals 
were found in it. 
One hundred gms. from slice No. 7 were dissolved in 
hydrochloric acid to which some sulphur dioxide had been 
added to remove any free chlorine. The insoluble residue 
amounted to 2°3777 gms. and yielded one speck of white 
and one speck of yellow metal, both were soluble in nitric 
acid. 
Ten gms. of the planings from slice No. 7 were treated 
with acetic acid, the insoluble residue amounting to °2594. 
gm. resembled that left by hydrochloric acid, and was 
apparently made up of schreibersite, perhaps some cohenite, 
and a little carbon. It contained 47°02% of iron, 25% of 
nickel and 3°42% of phosphorus; it is intended to obtain 
more of this acetic acid residue and submit it to further 
examination.
