Against progression theory, ranges so progression; but consider probability of more morphological differentia & as each differentia implies adaptation to surrounding animals & physical agencies more perfect. ? like man of war? If any type is indeed parasitic, then less need of active energies & may become degraded. Yet Owen says great differences in complication of Entozoa.

p. 431 urges The Crinoids as highly organised as Asteridæ, & the prevalent notion that they resemble the larval forms of other echinoderms upset by discoveries of Müller which shows that all echinoderms in youngest state are swimmers. Of cystideaus we know too little, as not recent speaks of Agassiz's dream on this subject.

[in margin:] I suspect Huxley here looks to earliest embryological age, which wd fail in Cirripedes. He has since made a strong distinction between true embryological & larval condition.

p 432. "The often repeated conclusion drawn from the nautilus-like form of the shell of Lituites & other lower Silurian genera, that there were tetra-branchiate cephalopods, ceases, as Mr Austen has well shown to have much weight when we consider that if we did not happen to be acquainted with the animal, the same thing wd be & indeed was said of Spirula".

Argue it is more than probable that Bellerophon was

a Heteropod, the most-highly organised of the Mollusca cephalophora

p 432 shows from Owens own writing read chp. VI. p. 148 on Fishes that the dermal plates & cartilgin skeleton but signs of lowness

p 434. He shows that amount of cartilage or incompleteness of the ossifying process bears no sort of relation to the position of Fish in the Scale. (see Prof. Williamson Phil. Trans. 1851) Kölliker has shown that the Helmichthydæ are "osseous fishes, almost without bones, & with a chorda extending to the skull & almost avertebrate."

p. 435. Lepidosiren is according Owen the highest grade of fishes & here the bands of vertebra remain as a continuous chondro-gelatinous chord.

[57]

p. 436. With respect to Heterocercal tail, the Lepidosiren has no tail-fin at all; in which it resembles Pterichthys &c. Again the Salamandroid Lepidosteus with ball & socket vertebra is accounted amongst Ganoid fishes the highest, has a heterocercal tail while Amia, which has ordinary vertebrae, has the tail homocercal.

p. 437. The branchial clefts are here absurdly mistaken for a branchial apparatus.

p. 426. Creation in the manner of law" is the Vestiges own proposition.

Law is a term "to express the orderly manner in which the will of God is worked out in external nature".

∴ Creation took place in the orderly manner in which the will of God is worked out in external nature.
