“Electromagnetic Theory”
by Professor J. A. Stratton.

 During the investigations of Y. Mushiake in the 1940's he repeatedly
studied “Electromagnetic Theory” 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.
