64/87 endured sea water for 28 days

18/94 floated (dried) above (much above/ 28 days)

∴ 64/87 of 18/94 = 1152/8178 = rather above 1/7 or rather more &  & 1/10 = stat .140

The proportion of any flower which cd be transported across sea for 28 days & germinated = [calculations not transcribed] = geographical miles

No doubt tossing of sea wd make plants sink much sooner, but then average far above 28 days
