by Professor J. A. Stratton.
During the investigations of Y. Mushiake in the 1940's he repeatedly
studied $B!H(BElectromagnetic Theory$B!I(B by Professor J. A. Stratton and he found
many misprints. In order to make sure whether he was right or not,
he sent a letter with a list of the misprints directly to Professor Stratton.
Then Professor Stratton kindly gave him a letter of answer
acknowledging the all items of the list as misprints.
The letter of Professor Stratton is shown below.
