II. Soft-Iron Wires. 
Wires of about the same gauge as the steel were used, but, except one of them, bore 
only about 28 lbs. instead of 230. All of three or four kinds tried agreed with the 
steel in (1). 
The first tried behaved (except a seeming anomaly, hitherto unexplained) in the 
reverse manner to steel in respect to (2), (4), (5), and (6) ; it agreed with the steel in 
respect to (7). Another iron wire*, which, though called “soft,” was much less soft 
than the first, agreed with steel in respect to (1) and (2), but [differing from steel in 
respect to (3)] showed greater effects of weights on and off when the magnetizing 
current was flowing than when it was stopped. 
Other soft-iron wires which were very soft, softer even than the first, agreed with all 
the steel and iron wires in respect to (1), but gave results when tested for (2) which 
proved an exceedingly transient character of the residual magnetism, and were other- 
wise seemingly anomalous. 
The investigation is being pontinued with special arrangements to find the expla- 
nation of these apparent anomalies, and with the further object of ascertaining in 
absolute measure the amounts of all the proved effects at different temperatures up to 
100° Cent. 
[Postscript, Jan. 1877. — The proposed continuation of the investigation is still going 
on. A part of it (of which an abstract, communicated to the Royal Society at its next 
ordinary meeting after the communication of the preceding paper, has been published 
in the ‘Proceedings’ for June 1875) completely explains the “seeming anomalies” of 
§§ 194, 195, above.] 
* It was tested magnetically with weights up to 56 lbs., and broke, unfairly however, when 63 lbs. were 
hung on.
