Note 126 — Chapter III · THE AMOUNT OF FINE EARTH BROUGHT UP BY WORMS TO THE SURFACE.

This case is given in a postscript to my paper in the ‘Transact. Geolog. Soc.’ (Vol. v. p. 505), and contains a serious error, as in the account received I mistook the figure 30 for 80. The tenant, moreover, formerly said that he had marled the field thirty years before, but was now positive that this was done in 1809, that is twenty-eight years before the first examination of the field by my friend. The error, as far as the figure 80 is concerned, was corrected in an article by me, in the ‘Gardeners’ Chronicle,’ 1844, p. 218.
