autographic curve, from which fig. 4 was plotted, showed that the 

 first effect of the added aluminium is, as might be expected, to lower 

 the temperature of the gold to a point a which proved to be close to 

 its solidifying point, 1045; the temperature instantly rises, however, 

 to a point &, which is 225 higher than the initial temperature of the 

 gold. The experiment is not strictly quantitative, as the perfect 

 admixture of the aluminium could not be ensured ; but it is probable 

 that true combination of aluminium and gold has taken place, which 

 would doubtless greatly affect the physical constants of the mass.]
