They commenced to melt a little below and to solidify a little above these points, which 
were taken for perfect fluidity or opacity. Generally in solidifying, the crystallization 
commenced at one point, and spread gradually through the capillary tube. 
The density varied with different portions of one and two, from below 0.7487. to 1.0, 
and was ascertained, by immersing specimens (freed from external air globules) in ether of 
the above density, alcohol of density 0.8365, and distilled water. The ash,"no doubt, 
varied also; but the following determinations were made with the whitest portions of one 
and two: viz.: those of the density of ether. No. 1, contained 0.573 per cent. of ash, 
(1.135 gave 0.0065) which effervesced with acid, and contained principally, lime, with 
traces of chlorine, sulphuric and phosphoric acid, also iron, potassa soda, and_ (doubtful) 
magnesia. The melting point of this portion was 52°, 53°. No. 2, gave 0.18 per cent. 
of ash, (1.109 gave 0.002) which contained the same substances as number one. The 
melting point of this fat was 53°, 55°. 
The two specimens of adipocire were melted with about one and a half times their weight 
of ordinary alcohol, filtered hot, washed a couple of times with hot alcohol, and pressed, the 
residue being weighed. This gives an approximate per centage of the membranous and 
fibrous matter, which is rather too low, owing to a little fat remaining in the residue and 
filter. The specimens of adipocire were picked as far as practicable from dark pieces.
