     The cloud point of a liquid is a measure of the degree of
     crystalization in a stock that can be measured by the refractive
     index.  It has been suggested that the percentage of I8 in the
     base stock is an excellent predictor of cloud point using the
     second or third order polynomial.

     The data in the `cloud' data frame were collected on stocks with
     known percentage of I8. The components are as follows
