Some 1843 translations of ancient letters, including Isidore of Pelusium

In 1843 William Roberts translated a selection of the letters of Isidore of Pelusium into English, as part of his book A History of Letter Writing from the earliest period to the fifth century.  I stumbled across a copy of the PDF which I must have downloaded ages ago, while looking around my hard disk for something to read during a period of no internet access.  Isn’t Google Books wonderful?  The book also contains letters of Phalaris, Cicero, Apollonius of Tyana, Synesius, and so forth.  I will scan these and make them available in due course.
