a Letter to Sir Hans Sloane, Bart . Pr. Coll , 
Med. By Patrick Blair, MB. F. <!{. S. 
Bojlon , Dec, 31. 1721. 
Honoured Sir , 
I T is no finall Satisfa&ion, that what I advanced 
in my Botanick Effays is now fo fully confirm’d by 
Experiments made by fome curious Gardeners, among 
whom is Mr. Philip Miller , who writes me, 
November 11, 1721. 
1. That in Purfuance of my Advice he feparated 
the Male Plants of the Spinage from the Female j the 
Confequence was, that the Seeds did fwell to the ufual 
Bignefs j but when he fow’d it, it did not grow after- 
wards. He fearched into the Seed, and found it want- 
ed the PunBum Vita, which perhaps might have been 
the Cafe with Mr. Geoffroy \ but if not, the female Em- 
bry ones might have been impregnated another Way, as 
he experimented with twelve Tulips, which he fet by 
themfelves about fix or feven Yards from any other, and 
as foon as they blew, he took out the Stamina fo very 
carefully, that he fcattered none of the Duff, and about 
two Days afterwards, he law Bees working on Tulips, 
in a Bed where he did not take out the Stamina , and 
when they came out, they were loaded with the Duff on 
their Bodies and Legs: He faw them fly into the Tu- 
lips, where he had taken out the Stamina, and when they 
came out, he went and found they had left behind 
them •
