1983,

The formula for the flow alignment angle ^{0 is} correctly given by equation (4.1). ^{In the}

^below (4.1)

it should read :

For

rod-like molecules (It

^{0) À -1}

^{2 0}

³ S/(2

S) ^{and for}

^disc-

like molecules (I1 -+ 0) ^{À - 1}

^{2 0}

³ S/(4 - S). ^In the latter

0 varies between (for ^S

0) ³ n/4 (and

nl4) ^and (for ^S

1) n/2. ^Thus, for discotics 0 decreases with increasing ordering

^In figure ^{4b the}

n-vector

should be reflected with respect

the y-axis.

We would like

thank T. Carlsson, ^{who drew}

^attention

the latter point.
