Philada. Feby 7th. 1807
The American edition of the nautical Almanac for the year 1809 being just published, I have the pleasure of sending you a copy; as also a copy of Garnetts Requisite Tables. In these you will find several valuable additions & improvements not to be met with in the English edition—and I have little doubt that these Almanacs & Tables will in a short time supercede the necessity of importing the English editions, altogether.
Mr. Garnett has just commenced the publication of a practical treatise of Navigation, which, from his known abilities, I am persuaded will be far preferable to any of the modern compilations on that subject.
As soon as his Almanac for 1810 is published I shall not fail to send you a copy from the balance still in my hands.
I have the honour to be with the greatest esteem Your obed. Servt.
