Page 390, 2nd paragraph, last sentence, refers to "the second parameter, nh,". The second parameter is nv. Also, the discussion repeatedly refers to variable nm, which in the class is nmax.

Hi, Dave.
Yes, I agree.
nh = nhash = first argument in constructor
nv = nmax = nm = second argument in constructor

Probably we should change the argument nv to
nm in the code, and change "second parameter"
to "first parameter" in the text.
