The same ellipsoid was removed from the carrier and replaced 
with Khotinsky cement; one could easily understand that very strong 
strain-magnetic phenomena might be occasioned by forcibly driving 
it into its mount. At the same time it was for the new experiment 
displaced through a different angle of rotation with respect to its 
major axis; by this operation the sign of the change of zero point 
as a function of the field was reversed.
