37. Observations on the Zoonomia ofErasmus Darwin^ M. D. by Thomas Brown, esq. Edinburgh, 1798. — V.

In the external world we merely know a change of position. Oxygen, hydrogen, a calorie exista : thev change their place : water exists. When one of the ingrédients of a compound substance is added to the others we term it the cause of the oompound ; because, when it is added, the compound exists...
