M'Donnell's was "On the Homologies of the Electric Organ of the Torpedo," afterwards used in the "Origin" (see Edition VI., page 150).) M'Donnell, of course, pleases me greatly.

But I am very curious to know who wrote the Protozoa article: I shall hear, if it be not a secret, from Lubbock.

It strikes me as very good, and, by Jove, how Owen is shown up--"this great and sound reasoner"! By the way, this reminds me of a passage which I have just observed in Owen's address at Leeds, which a clever reviewer might turn into good fun.

He defines (page xc) and further on amplifies his definition that creation means "a process he knows not what." And in a previous sentence he says facts shake his confidence that the Apteryx in New Zealand and Red Grouse in England are "distinct creations." So that he has no confidence that these birds were produced by "processes he knows not what!" To what miserable inconsistencies and rubbish this truckling to opposite opinions leads the great generaliser! (119/4.

In the "Historical Sketch," which forms part of the later editions of the "Origin," Mr.Darwin made use of Owen's Leeds Address in the manner sketched above.
