EVANGELICAL MISCELLANY.

NOVEMBER, 1845.

GEOLOGICAL DETAILS.

It has been supposed that the study of geology has an infidel tendency, and that its investigation discloses to us such evidences of confusion and disorder, as might lead the unthinking mind to the conclusion, that this earth had at one time been abandoned entirely to chance. Geology claims also such a very protracted term for the duration of material things, as may have induced some timid christians to

suppose that its disclosures are inimical to the account given in the sacred Scriptures of the creation of all things. But it should be borne in mind that we have no revealed system of chronology; and although, by collating one text with another, we may estimate with tolerable certainty the period of man's introduction upon our earth; we have nu data whatever for ascertaining how long the earth had existed before that period, and which constitutes the very interval with which alone geologists have to do.

Our engraving for the present month offers a triumphant refutation to the allegations of infidelity that there appears such a recklessness and disorder in the geological world, as does away with the necessity for the all-wise superintendence of a Deity; since it affords us the clearest possible proof that the same wisdom, power, and goodness were

Y

manifested in the early days of our earth's history as are still conspicuous in every department of the natural world.

Figure 1 represents the tooth of that gigantic fossil animal the megatherium, represented in our volume for 1840, p. 1; and fig 2, gives longitudinal sections of four of these teeth in their natural position. Each tooth is composed of three separate substances, of different degrees of hardness, designated by the letters a, b, c. Now the hardest of these (), called enamel, occupies the centre of the two prominences in each tooth, and forms a sharp cutting edge, guarded on the outside by a softer substance (a) called crusta petrosa, exactly as in those carpenter's tools, which are formed of hardened steel welded to iron. The central portion of the tooth (c) is formed of ivory, another soft material ; the reason for which is obvious, as the cutting edge of the opposite tooth comes in contact with it, and would necessarily receive damage did it grate against a material as hard as its own. But under this beautiful arrangement it falls into the comparatively soft bed prepared to receive it, which forms a kind of natural hone to the natural chisel opposite.

Figure 3 represents a curious creature found amongst the earliest of animal existences occurring in the earth's strata ; it is called a trilobite, from the circumstance of its body being apparently divided into three lobes or parts. Infidels have cavilled at the apparently imperfect development of the legs, as evidencing a faulty organization, though it has been satisfactorily shewn that they are amply sufficient for all the purposes required. And, as if to sweep away all possibility of objection, the eye has been demonstrated to be a perfect microcosm of wisdom and contrivance.

Figure 4 exhibits an enlarged view of this remarkable organ, which, as it stands erect from the head, resembles a semicircular bastion covered with lenses or facets of the most complicate and beautiful character, somewhat resembling those of the common house-fly. As there were two of these natural watch-towers, one on each side of the head, they would sweep the entire horizon, and enable the trilobite, as he lay at the bottom of the water, to keep a constant look-out on all sides at once.

Not less admirable was the construction of the eye of the ichthyosaurus, a part of which, consisting of two of the sclerotic plates, is represented in fig. 5. These plates were arranged around the eye-ball in the manner shewn in figs. 6, 7, and 8; the first of these belongs to the golden eagle, the others to the iguana, a recent lizard.

The use of these sclerotic plates was to regulate the convexity of the lens of the eye by the degree of pressure exerted upon it, so as to adapt it to the purposes either of a telescope or a microscope, enabling the animal both to observe its prey at a great distance, and to examine it with the utmost accuracy when near at hand.

Surely such evidences of consummate wisdom and goodness could only have emanated from the Great All-Wise himself, whose tender mercies are over all His works !

THE PARSON'S CHOICE MEMORIES.

CHAP. XI.-THE LONDON SEMPSTRESS. "I commenced my ministerial career,” said one of our party, when volunteering his contribution to our reminiscences, curate to a crowded church in the city of London, of which condition, one of the most painful circumstances to a conscientious man is the impossibility of knowing the people individually, or even the families, which, in some of the houses, are as numerous as the several apartments in each house.

“There was bread given away after the morning service on many Sundays in the year in my church; and I had sufficient influence with the churchwardens, to induce them to distribute it only to such poor persons as constantly at ended divine service. I was divinely guided (I speak with unfeigned gratitude I trust) to preach the gospel from the first opening of my ministry, as far as I saw its fulness; and farther can no man go. But although my views of the amplitude and vastness of redeeming love have, from year to year through the course of my life, been gradually on the increase, yet do I humbly thank my God, for the simplicity with which I was enabled to proclaim the glad tidings of salvation even during the early period of my ministry—having been made to see that the sinner has no other hope of justification but through the Lord the Saviour.

“I had been resident some months at this curacy, when one Sunday I perceived a very miserable, emaciated, sickly-looking woman seated on a bench in the aisle nearly opposite the pulpit, and I failed not to remark, that she seemed to be very attentive to my sermon. The text was in these words :—“They shall hunger no more, neither thirst any more; neither shall the sun light on them nor any heat, for the Lamb which is in the midst of the throne shall feed them, and shall lead them unto living fountains of water, and God shall wipe away all tears from their eyes.' (Rev. vii. 16, 17.) My discourse consisted only of explanations of this passage, with citations of other texts bearing upon the same views of the Saviour.

“The next, and the next occasion, brought the same figure of the poor woman in her scanty attire, and with her earnest upraised countenance before my eyes; and I saw with satisfaction as time went on, and there was no interruption of her attendance, that, although her garments wore the same threadbare scanty appearance, that a change had passed not only in the expression of her countenance, but in the arrangement of her attire-a clean though coarse apron and kerchief, evidencing a wish to look as decent as her narrow circumstances would admit.

• She came and came again ; but, as the churchwarden told me, never asked for a loaf after the first Sunday, when it was denied to her ; nor was it till many weeks afterwards that a loaf was sometimes given her without any solicitation on her part. At length I missed her from her accustomed place, and when I enquired about her, could obtain no tidings, as she was not a housekeeper in the parish, and no one seemed to know who she

46

was.
