As an explanationof the two well defined heat effects exhibited by this alloy, these photo-graphs also offer Httle that is enlightening. Thus it seems apparentthat the tin-rich constituent of the eutectoid may make its appearanceprior to the actual formation of the eutectoid, which certainly is not inaccordance with our ideas of eutectoid formation. Two pure copper-tin alloys, one containing a considerable proportionof excess a and the other only a slight amount, were qu
