This is just to note that in addition to having the sex skin sizes starting 
with 1999, we are almost finished adding the pcs coloration.  This was 
stimulated by Jacinta's pregnancy failure ms and the fact that everyone 
else uses pcs color to determine pregnancy whereas we have always used 
earlier criteria and now have the hormonal data as well in some cases.  We 
have noted that pcs color change comes later; it is also very variable in 
timing, but as far as I know, neither we nor others have quantitative 
information on this.  We will now have it electronically for the years for 
which we have hormonal data (and may soon be able to related color change 
to hormonal change) and for most of the years for which we have data on sex 
skin size electronically.
