Dampier's last voyage to New Holland P 127.— Caught a shark 11 ft long. "Its maw was like a leathern sack, very thick & so tough that a sharp knife could not cut it: in which we found the Head & Boans of a Hippotomus; the hairy lips of which were still sound and not petrified, and the
[page 9]
jaw was also firm, out of which we pluckt a great many teeth, 2 of them, 8 inches long, & as big as a mans thumb, the rest not above half so long; The maw was full of jelly which stank extreamly."— This shark was caught in Shark's Bay. Lat 25°. The nearest of the E. Indian Islands, namely Java is 1000 miles distant! Where are Hippotami found in that Archipelago? Such have never been observed in Australia
[page 10]
Dampier also repeatedly talks about the immense quantities of Cuttle fish bones floating on the surface of the ocean, before arriving at the Abrolhos shoals.∦—
N.B. The view of the Volcanos of the chain of the Cordilleras as arising from the expulsion of fluid nucleus through faults or fissures, produced by the elevations of those mountains on the continent of S. America is inadmissible may have happened from incipient elevation. The volcanos originated
[page 11]
in the bottom of the ocean. & the present Volcanos have been said to be merely accidental apertures still open.— The fault like appearance arising from the manner of horizontal upheaval of the shore of the Pacifick is 60 miles distant from the grand ancient volcanic axis of the Andes.— Has this fault determined side of volcanic activity. That axis was produced, from a fissure in a deep & therefore weak part of the ocean's bottom.

In a preface, it might be well to urge, geologists to compare whole history of Europe, with America; I might add I have drawn all my illustrations from America, purposely to show what facts can be supported from that part of the globe: & when we see conclusions substantiated over S. America & Europe, we may believe them applicable to the world.—

My general opinion from the examination of soundings, from about 80 fathoms & upwards, that life is exceedingly rare, at the bottom of the sea.— certainly data insufficient, yet good (I suspect fragments of shells will generally be found to be old & dead) (I have not kept a record) In looking over the lists of organic remains in De la Beche, for the older formations I must believe they the limestones have been formed in shallow water: so have the Conglomerates: Yet this view is directly opposed to common opinion

I look at the cessation northwards of the Coal in Chili as clearly bearing a relation to present position of Coal Forests. These thick beds of Lignite stratified with substances so like the Coal measures in England (Excepting Conglomerates?) & absence of limestone? have been collected on the open coast. Perhaps as at Concepcion. favoured by basin formed by outlying rocks; (such as between Mocha & main land). [illeg] At Carelmapu.— Within Chiloe:—

The action of sea A.B. will be to eat in the land in line of highest tidal action. this will at length be checked by increased vertical height thickness (DZ) of mass to be removed & from the resistance offered to the greater lateral extension of the waves. by the part beneath the band of greatest action not having been worn away.— If the level of the sea was to sink by very slow & gradual movements to line (2). The part (o) which was before beneath band. of greatest action, would now by degrees be exposed to it, & the result would [be] a uniform slope to base of cliff (Z). to which point the waves would not reach. If now the ocean should suddenly
[page 40e]
fall, (3) the case would be as at first. & according to the greater or less time of rest. so would the size of the triangular mass removed vary.— The gradual rising continuing. a another sloping platform would be made, & so on.— This is grounded on the belief of constant rising with successive periods of greater activity & rest.— Such changes could be shown (as represented), along line of coast.— [Fig. 2] Mem San. Lorenzo; Valley of Copiapo & parts of coast of Chile.—
Must first explain top of tidal band of action.
[page 41]
This case differs. I think. from Patagonian steps, because the deposition & accumulation is brought into play
As in Ocean & Air; there are likewise differences of temperature at equal distances from centre of rotation & a circulation owing rotation in fluid matter of globe. must there not be a circulation however slow & weak.; (cause of not accumulation of Coral limestone in intertropical) hence varieties of substances ejected from same point. & changes.

Mr Conybeare introduct to Geolog— "Between the height of same beds, deposited in different basins; little or no relation appears to exist be made out, but in those belonging to the same district there seems. I think, little ground for skepticism, as to the general truth of the proposition."— If such can happen in troubled England; the more minute equalities
[page 47]
of elevation, may well be preserved at Patagonia. The English fact is astonishing consult book itself. P. xx: same fact is indeed shewn ? by the parallel bands of formations on any Geolog Map: Quoted from Daubeny P 402: likewise, mean height of tertiary. being less than secondary:— consider arguments for oscillation of level independent of mineralogical nature & dependent: & then how wonderful level of same beds should have been kept; it shows that throughout all England, whole surface oscillated equably.—
[page 48]
These facts become easy if we look at the action as a deep & extensive movement of viscid nucleus, which in any one country would produce equable effects.— though so immense to short breathed traveller Mountains, which in size are grains of sand, in this view sink into their proper insignificance; as fractures, consequent on grand rise, & angular displacement, consequent of injection of fluid rock.—

It has been common practice of geologist.
Lyell considers (P 84 Vol III.) whole of Etna series of coatings; hence it will be necessary to state all arguments for believing that there must be a central core of melted rock— I think the strongest is the consideration of the state at a grand eruption when whole summit of mountain is blown off; & again when in great crater. different little craters are all burning, surely there must be somewhere below a field of fluid rock.— In the discussion it will be better not to refer to Lyell. but merely to
[page 58]
state these reasons, & saying that they refer to central nucleus & that envelopes no doubt existed. These higher portions probably formed Isls from which proceeded pebbles & on which trees grew.— ? Are not the dikes in upper strata. quite different from the Porphyries: certainly appearance leads me to believe mere fissures filled up.— the appearance will here be the strongest argument:— ⸮ Consider causes for subaqueous crater being of diff: form subaerial one?— In former not so much; or no rapilli; & from action of water probably not so much aluminated.
[page 59]
As argument in favor of lines of anticlinal violence crossing lines of crater, arg state that all the great Volcanoes, have been elevated considerably, which shows an afflux of inferior melted rocks to those parts.
Are not the dikes generally vertical? if so posterior to elevations? & not sources of lava streams.— Urge not tilted strata.—
It will be well to urge the case of St Helena, where dikes certainly have not been points of eruption.
Nobody supposes that all the dikes in Cornwall or in the coal measures have been conduits to volcanoes.—

Talking of the cricket valley the most remarkable feature in the structure of Ascension give as an example the great subsidence at the famous eruption of Rialeja, & the more true analogy from the Galapagos—
Mr Lyell. P. 111 & 113. seems to considers that successive terraces mark as many distinct elevations; hence it would appear he has not fully considered the subject.—
S. America in the form of the land decidedly
[page 61]

The question of shell's concretions, living only in that spot & being cause of concretion; or being only preserved in that part, having lived over whole bottom is important; because in this latter case, we cannot judge whether such fossils. lived in groups or not.

Ferruginous veins of this figure [sketch] in sandstone: evidently depend on a concretionary contraction: the fact is in alliance with those balls at Chiloe, full of sand.— the scale quantity of iron being there in excess.— If veins [Fig.] are secretionary, so are all those plates in Australia.
