Summary

This letter is from Alfred Vail to Joseph Henry, but it was written by Samuel Morse. The letter expresses Vail's discovery of Henry's grievances against his recently published work. Vail assures Henry that he did not consciously commit an injustice against Henry by not citing Henry's experiments in his book "The American Electro Magnetic Telegraph: With the Reports of Congress, and a Description of all Telegraphs Known, Employing Electricity or Galvanism". He also points out that he had requested information from Henry many times, but Henry never responded to his inquiries. Vail is preparing to make another edition of his work, and he assures Henry that he is more than willing to receive Henry's work, so that it may be properly cited. Vail also attests to the innocence of Morse in the preparation of his book (Henry had lodged his grievances against Morse more so than Vail, although it was Vail's book).
