 pg. 19  Eq. (1.11.32) contains an extra left bracket.
 Pg. 276  the functions A2,3(w)
are actually the denominators of the functions referred to on that page. This is not stated as such.
 Pg. 62  the 4th line should read "Using this result in Eq. 3.6.60 leads to" and 
Eq. 3.6.63 and 3.6.64  the argument of the Hankel function should have a cosj
instead of a sinj. (Eq. 3.6.67 is correct)
 pg. 149  Eq. 6.5.14 for T_{nm} should be multiplied by 1/2, the k's
in the H_{0,1} and H_{1,0}
should not be there, and the last term in the last line should
be h^{(1)}(kr_{n+1})
h^{(2)}(kr_{n})
 pg. 32  Fig. 25 has the wrong curve for a ceramic magnet  the wrong
quadrant is shown. The correct curve slops down from the correctly
shown Yaxis value and intersects a point at 1.7 Oersteds and 2.0
kilo Gauss. It then falls off rapidly. This error has no effect on the
discussion in this section.
