Each part of the flower, and he directly adduces the syngencsian cfass, 

 *a e h \tT artt wnicn contains the very plants, that (if he had dissected 

 cular part of the them ) would have proved the mistake of his argument. But 

 as all my opinions are formed on dissection alone, I have no 

 theory to carry on, if I deduce from what I see in the mi- 

 croscope a false conclusion. I am very ready on convic- 

 tion to give up the point; but as I reason from no other 

 (fata than dissection, I would ask him these simple questions: 

 why, if the nourishment of each part of the stem is not 

 confined to each different part of the flower, does the whole 

 arrangement of the stalk alter, the moment it gets to the 

 flower stalk? why are there particular vessels, to confine 

 and carry the juice to each peculiar part, if it was not of 

 consequence, that this juice should touch no other places? 

 for what purpose is the curious and artificial management in 

 the bottom ajid top of a seed vessel, which enables the 

 dissecter to say, u there are live divisions of little vessels 

 proceeding from the wood, I know therefore (though I do 

 not see it) that this must be a pent andrian flower ; here is 

 but one middle vessel proceeding from the circle of life (for 

 the pith stops,) it is therefore of the order pentandria mo- 

 nogynia: here are five divisions of little vessels proceeding 

 from the inner bark, it must therefore have Jive petals ? 

 'This is a simple way of showing the truth, and may dis- 

 gust, but it is truth, and should not do so ; I ardently wish 

 to convince; because I am convinced myself. Cut above 

 or below the seed vessel of a lily, a violet, a tulip, and 

 conviction will I think certainly follow. Why in cutting 

 below or above the seed vessel of a syngenesian flower, can 

 you directly tell whether it is superflua, aequalis, or se- 

 gregata? Look at the bottom of the seed vessel of the 

 sonchus; every pin hole of the vessel of the male is carried 

 up by corresponding vessels in the outward cuticle of the 

 seed : this I have proved in the solar microscope, (diminu- 

 tive as it is) it is thus carried up till it meets and joins the 

 'ligature of the males; and the female liquor is protruded 

 through the inside of the seed, and is perhaps one of the 

 . strongest. proofs of the impregnation of the female. In the 

 syngenesian class (".see Plate IX) the delicacy of the vessels, 

 which may be supposed too small for a liquid to flow through, 



must
