 fixed upon, fertile.* 





SECOND EXPERIMENT. 



In the month of April I sowed Hemp-seed {Canabis) in two pots. 



The young plants came up in such abundance, that each pot contamed thirty, or forty, 



^placed both to the light on a window-seat, but in opposite parts of the house, so that all 



communication was necessarily prevented. 



In both situations the Hemp flourished greatly. 



In one of the pots I suffered the male and female plants to grow together, to flouush, and 

 prodlelit, which was ripe in the month of June, and afterwards being macerated m water, 

 and committed to the earth, shot up within twelve days. 



But in the seeond I plucked up all the male plants as soon as they had advanced, so that I 

 could discern the anther-bearing males from the pistiUeanng females 



The surviving females indeed flourished, and copiously presented the, long p stds, bu the
