  In this note we show that Frobenius split smooth, projective threefolds are
Hodge-Witt (using a criterion for the degeneration of the slope spectral
sequence of smooth projective threefolds which we prove), and that smooth,
projective Frobenius split varieties do not have exotic torsion in their slope
spectral sequence. We also record a few simple observations on Frobenius split
threefolds. This paper complements authors paper with C. S. Rajan ``On
Frobenius splitting and ordinarity'' which is also available on this archive.
