This, as well as other experiments of the same class, shows that when tested in 
this way the critical point, at which the sign of the effects of heating and cooling 
(from 100° to, say, 6° C.) changes, occurs at a very low value of the magnetisation. 
In the above case it was reached when 3 was about 8, or about the yyo part of the 
so-called saturation value of 3- 
§119. (Feb. 5, 1883.) A similar experiment was made with an annealed 
specimen of wire cut from the same bundle as the last, and also 40'5 centiins. long.
