Does the 158 CELL-SOULS AND SOUL-CELLS. want of a nervous system in these denote the lowestlimit of soul-life ? Or is there in these cases a soulwithout any nerves ? Well-known scientific men—e.g.,B. Yirchow and Du Bois-Reymond—answer the latterquestion in the negative, and maintain that no one canspeak of a real soul-life in these nerveless animals.We are of a different opinion, and we found it on thegeneral opinion of all zoologists who have employedthemselves for a long time and with great perseverancein close observations on these animals destitute ofnerves.
