I wrote a few minutes ago:
"Incidentally, for the tables taxonomists, Ward's tables are in the same
general category as Turner's and Thompson's (Bowditch III from 1837) which is to
say that they are distilled series method, derived ultimately from Lyons'
method, in which refraction and the quadratic corrections are combined together
in a rather long, but relatively simple look-up table. These were popular
methods."
That should read "(Bowditch II from 1837)". Bowditch's *Second* Method from
1837 until 1880 was identical to Thompson's method.
