volition, in the combination of a mind that deals with the 

 conditions of existence interwoven with as it were another mind 

 capable of abstract thought and creative imagination, we have a 

 duality corresponding with that of the body. In the vegetable 

 kingdom, also duality is well represented. Besides the sexual 

 distinction to which I have already alluded, we have the fact 

 that ovules are universally produced in pairs. The typical 

 carpel is, in fact, a pod with two seeds. Sometimes, as in the 

 filbert, one seed gorges himself to gigantic dimensions at the 

 exjiense of his poorer brother, who dwindles to a husk ; sometimes, 

 as in the chickweed, the two seeds become as many score ; but 

 the unripe ovary always tells the same tale of double birth. 

 The growth of minerals is more obscure, but recent researches 

 liave thrown much light upon the modes in which minerals 

 crystalhze or congeal. Throughout these investigations great 

 stress is laid upon the law ofi^olarity. To the eye of the modern 

 philosopher every particle is but a little magnetic needle, having 

 its poles of attraction and repulsion ; and this polarity has been 

 claimed by Tyndal not only for the particles composing the 

 crystalline structure of minerals, but even for those of the human 

 brain itself I have good authority therefore for saying that even 

 minerals are dual. 



Number Three comes next ; the type number of all that 

 great division of plants knoAvn as the Endogens, or Monocoty- 

 ledons. These plants, comprising every variety of vegetable 

 production, from the tiny grass to the gigantic cocoa-nut paJm, 

 from the coarse bulrush to the delicate lily of the valley, 

 differing in all else, imite in this peculiarity that their leaves, 

 under all their modifications, occur in whorls of three. The 

 flowers have a calyx of three sepals, a corolla of three petals, one 

 or two sets of three stamens, and an ovary composed of three 

 carpels with a trifid stigma. In many of the sedges this 

 character is extended to the stems, which are triangular. In few 

 of Nature's groupings does she show more regularity than in this.
