Electric field strength (commonly called 'E') was subtracted from 
magnetic field strength (commonly called 'H') by Einstein.

E has [V/m] as units and H has [A/m].

To subtract E from H would mean [A/m - V/m] =[(A - V)/m].

(Einstein used only the X-components called 'N' and 'Y', which should 
have similar units, nevertheless. The used phrase 'force' instead of 
'field strength' was actually wrong.)

Now ... ..(N - v/c*Y)... contains an illegal operation, because it 
requires to subtract Volts from Amps. (sorry: I wrote it the other way 
round, but that does not matter, because subtraction is also a form of 
addition).

I have complained about this operation and you are still not able to 
justify that by other means then by referencing to the same units used 
in the cgs system.

My argument, that this would justify other operations, which are 
regarded as illegal, like subtraction pressure from weight, hence must 
be illegal itself, you were unable to disprove.

So in effect you are unable to defend Einstein's position.
