Summary
Sunk Under 10 days |
Floated over 10 under 25 |
Floated over 25 to 90 & upwards day |
|||
Not dryed 72/94 |
Dried 62/94 |
Not dryed 15/94 |
Dried 14/94 |
not dried 7/94 |
Dried 18/94 all these above 28 days See Back |
Not dryed Walnuts Nuts & Not dryed Asparagus 22-23 Lychnis dioica 21-22 Honeysuckle 3-4 days Helosciadium 1-2 Barbery Papaver 5-6
Viscaria 2-3 Dianth 1-2 Narthecium 6-7 Sweet Briar 2-3 Juniper 12-13 |
Dryed. 90-day, still floating -germinated after 90 days - 74 days
85-86- germinated 44-45 21-22 whole plant 21-22 seeds- thrown away after 90 days? germinated well 40-41 14-15
30-31 28-29 16-17 21-22 38-39 |
average 67 2 beyond patience |

87 [-] 23 [=] 64
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
