'^4i OBSERVATIONS AND EXPERIMENTS ON PUS. 



neutral salts, and with carbonate of potash, it produced a 

 viscid semitranspareijt mass like expectoraied half transpa- 

 rent matter-^ex posed to fire in a platina crucible, it was in- 

 flamed, but did not emit an offensive smell, and aiter conti-r 

 nuing the ignition, the residue was a particle of half fused 

 matter, not amounting to ,^Vtr of the pus after ablution, nor 

 above -j-J^ pf the same matter exsiccated ; it consisted of 

 phosphate of lime and vitrified mutter.-r-no ammonia was 

 perceivable, on mixing lime with this washed pus; nor mu- 

 riatic acid on adding sulphuric acid.

agitated in wa-^ ^" halt a pmtol distilled water, produced a milky fluid, with 



^^i"' a number of small curdy particles suspended,' but very few 



leafy or fibrous pieces or clots. 



{b) The serous pus he\ns^ treated as juft mentioned (c), 

 the same appearnnces ensued. 



(c) The curdi/ pus being agitated in the same manner in 

 •water, a number of clots, leafy, and fibrous masses, were 

 seen suspended among fine small cuidy particles in a pearly 

 liquid. 



(f?) The viscid pus hc'mg treated as just said, it required 

 long continued and violent agitation, to diffuse it through 

 the water, and then the appearances were as last de- 

 scribed. 

 Boiled. g^ pyg ^f jjj^y ]^jp(]^ after boiling in twenty times its 



quantity of water, was quite as globular under the raicro-r 

 scope as previously. With a smaller proportion of water, 

 the mixture became very turbid, sometimes clots were 

 formed in a pearl liquid, in which a fine sediment took 

 place, which appeared much more globular than the clots 

 or curdy masses, 



4. In general, water in which pus has been agitated re- 

 mains somewhat milky, with an abundant c'ose white sedir 

 ment ; but after two, or three, or more ablutions, the 

 water becomes clear qa standing, and the sediment more 

 curdy.
