near the furface of the ground ^, which h 



which was then 



been called the coronal root, was furniQied with a ftem and leaf, c, d, 



fcion, ^,/. This wheat-plant 



in, and pur- 



and with a fecondary fl:em 



_.Jifting of only two flems was replanted in my garden, ai 

 pofely buried fo deep as to cover the two or three firft joints of both 

 the ftems beneath the foil ; that is as high as the letter/, where the 



fecondary ftem 



purpofely cut off 



On taking up this plant with fome others on September 24, it had 

 {fumed the form here delineated. The primary ftem, c,g, had (hot 



roots from the joint g, which I fuppofe to have hap- 



out 



new 



pened from its being too far advanced 



wh 



planted 



many 



other ftems of other wheat-plants, which had not been obtruncated, 

 had neverthelefs put forth one or more lateral ftems or root-fcions at: 

 the fecond or third joints, which on tranfplantation had been covered 

 with the foil. 



But the obtruncated ftem, e, 



h. like the firft ftioot from the feed 



had generated a new root-fc 



which had produced 



new 



ftems, as it approached nearer the furface of the earth 



/ 



and as thefe advanced into the 



and formed their leaves, oth 



new root-fcions were generated at k and /. Whence it appears, that 

 by decapitation, and a deeper immerfion in the ground, a fecondary 

 ftem in this plant became multiplied into five ; all which produced 

 perfea ears of corn ; and in other roots, which I had planted in a 



fimilar manner, the increafe was much greater : and efpecially where 

 one or more of the primary or fecondary ftems had been decapi- 

 tated. 



If a <yraln of wheat be dropped on the furface of the earth, and fuf- 



fered 



ftioot dow 



and to raife its ftem, which is the 



the 



procefs of nature, I fuppofe but one ftem would be produced ; as 



firft knot or joint of it would not be covered with earth, and could
