    I am sorry, I have forgotten one more remark to Cotter: Don't read the pages 
    232-235 in his book (description of Hall's method for clearing the lunar 
    distances). It is full of errors, largely surpassing the average level of 
    errors in the book. It is not worth labour to correct it, as its content is 
    not important - the method was devised only to be the definitely last created 
    one, when the lunar distances were being dropped from the Nautical Almanac. 
    Only the notion "horizontal refraction", created in parallel with the 
    well-known "horizontal parallax", sounds interesting and funny.
