The inconsistent spelling of "employe" (versus "employee") has been left as is.
The inconsistent capitalization of "Fleet street" versus "Fleet Street" has been left as is.
The inconsistent usage of "air craft" versus "aircraft" has been left as is.
In several places throughout the book, inconsistent usage of the degree symbol (°) has been left as is.
On page 31, "shiplike" changed to "ship-like" to be consistent with other usage in the book.
On page 31, "inclosed" changed to "enclosed" to be consistent with other usage in the book.
On page 67, "day-time" changed to "daytime" to be consistent with other usage in the book and with contemporary usage of the time period.
