NOTES. 
NOTE A. p. vii. 
Tue remark made at that period by the American publisher, in recom- 
mendation of his work, will not be uninteresting at this day in relation to 
Dr. Bowditch, who was then about twenty-four years of age. He says :— 
“For several new Tables and Additions to this work, the Editor takes 
this public opportunity of returning his thanks to Mr. Nathaniel Bowditch, 
of Salem, Fellow of the American Academy of Arts and Sciences, whose 
acknowledged talents, both as a theoretical and practical navigator, reflect 
high honor on the nautical character of his country.” 
The publisher adds, that one of the Notes (on Table XIV. of that edition) 
“was furnished by Mr. William Bowditch,’ who was a brother of Dr. 
Bowditch, and distinguished also for his mathematical knowledge. 
NOTE B. pp. viii. 
In going through this examination Dr. Bowditch made the last figure 
exact to the nearest unit ; and no less than eight thousand errors were dis- 
covered and corrected in the work of Moore, and above two thousand in 
the Requisite Tables; though of the latter Dr. Bowditch justly remarks, 
that most of the errors were in the last decimal place, and in many instances 
would but little affect the result of any nautical calculation. But, he adds, 
when it is considered, that most of the Tables are useful on other occasions 
where great accuracy is required, it will not be deemed a useless improve- 
ment to have corrected so great a number of small errors. — Preface to 
Practical Navigator, p. vi. edit. 1802.
