EX^ERmENTS ON WOOTZ. 



dfSerent parts of tlie fame inftrument. The efledii produced 

 by the conlrait ot colour is very beau-titul. Whether any 

 of' tliefe obfervations may be worth eomniunicating through 

 the medium of your moft ufcful Journal, is a queibon I beg 

 leave to fubmit entirely to your judgment. I have not tried 

 any of the efTential oils with folution of platina ; furtiier ex- 

 periments will probably be made with thefe metallic fohitions, 

 by thole who have more time, and a better knowledge of 

 thete fubjeds. Such purfuits, when the refults are frankly' 

 communicated, promife to benefit fcience, and muft ultimate- 

 ly prove ulelul to fociety. 



I remain with much refpe6l. 



Dear Slr^ your obliged Servant,

Appearances on vJnE half of this cake was heated to a fcarlet (liade, and put 

 ©/w(wu,No's!"'^^^'' ^^® cutting cliiflel; it was at firft ftruck lightly, then 

 reheated, and cut comparatively foft ; but a fmall crack had 

 over-run the progrefs of the chiflel. Its foflnefs in cutting 

 was attributed to an evident want of folidity. The other halt 

 cake felt harder under the hammer, but proved afterwards 

 Ipongy throughout the mafs. In the aft of cutting, a loofe 

 pulverifed matter was difengaged from fome of the cells, 

 poffefled of a fhining appearance. 



The fradures obtained in confequence of the divifion of the 

 half cakes, prefented a flattiQi cryftaUized appearance, more 

 referobling very white call iron, than fteel capable of being 

 extended under the hammer. One of the middle cuts was, 

 entirely cellular with cryftallized interiors, and incapable of 

 drawiDg J the correfjponding cut of the other half cake was-
