 To be specific:
 
 specific gravity of ethyl alcohol = 0.791
    "        "     " methyl alcohol = 0.810

Thanks for the info, Duane.  I didn't have the numbers handy.  As I mentioned 
to someone off the list, mixing volume and weight measurements (fluid ounces 
vs. ounces of weight) is sloppy engineering but hopefully not critical in 
this discussion.  What all this means is that alcohol fuel weighs about 8/10 
as much as the same volume of water.
