      Making use of the theory developed in Part I, the integrated values of the reflected and the anti-reflected intensity have been obtained analytically for an internal reflection of a perfect crystal. Three special cases are considered, namely a symmetrical reflection, an asymmetrical reflection and also when absorption is very heavy. It is found that when absorption is large, the formula for integrated reflection reduces to that for a mosaic crystal, which may be physically explained by the fact that multiple reflections are not allowed to play a prominent part owing to the beam being quickly attenuated by absorption.
