Or I will begin ab hora questionis, as Haly, Messahala, Ganwehis, and Guido Bonatus have recommended.' One of Sampson's great recommendations to the favour of Mr.Bertram was, that he never detected the most gross attempt at imposition, so that the Laird, whose humble efforts at jocularity were chiefly confined to what were then called bites and bams, since denominated hoaxes and quizzes, had the fairest possible subject of wit in the unsuspecting Dominie.

It is true, he never laughed, or joined in the laugh which his own simplicity afforded--nay, it is said, he never laughed but once in his life, and on that memorable occasion his landlady miscarried, partly through surprise at the event itself, and partly from terror at the hideous grimaces which attended this unusual cachinnation.

The only effect which the discovery of such impositions produced upon this saturnine personage was, to extort an ejaculation of 'Prodigious!' or 'Very facetious!' pronounced syllabically, but without moving a muscle of his own countenance.
On the present occasion, he turned a gaunt and ghastly stare upon the youthful astrologer, and seemed to doubt if he had rightly understood his answer to his patron.
'I am afraid, sir,' said Mannering, turning towards him, 'you may be one of those unhappy persons who, their dim eyes being unable to penetrate the starry spheres, and to discern therein the decrees of heaven at a distance, have their hearts barred against conviction by prejudice and misprision.' 'Truly,' said Sampson, 'I opine with Sir Isaac Newton, Knight, and umwhile master of his Majesty's mint, that the (pretended) science of astrology is altogether vain, frivolous, and unsatisfactory.' And here he reposed his oracular jaws.
'Really,' resumed the traveller, 'I am sorry to see a gentleman of your learning and gravity labouring under such strange blindness and delusion.
Will you place the brief, the modern, and, as I may say, the vernacular name of Isaac Newton in opposition to the grave and sonorous authorities of Dariot, Bonatus, Ptolemy, Haly, Eztler, Dieterick, Naibob, Harfurt, Zael, Taustettor, Agrippa, Duretus, Maginus, Origen, and Argol?
Do not Christians and Heathens, and Jews and Gentiles, and poets and philosophers, unite in allowing the starry influences ?' 'Communis error--it is a general mistake,' answered the inflexible Dominie Sampson.
'Not so,' replied the young Englishman; 'it is a general and well-grounded belief.' 'It is the resource of cheaters, knaves, and cozeners,' said Sampson.
'Abusus non tollit usum .-- The abuse of anything doth not abrogate the lawful use thereof.' During this discussion Ellangowan was somewhat like a woodcock caught in his own springe.

He turned his face alternately from the one spokesman to the other, and began, from the gravity with which Mannering plied his adversary, and the learning which he displayed in the controversy, to give him credit for being half serious.

As for Meg, she fixed her bewildered eyes upon the astrologer, overpowered by a jargon more mysterious than her own.
Mannering pressed his advantage, and ran over all the hard terms of art which a tenacious memory supplied, and which, from circumstances hereafter to be noticed, had been familiar to him in early youth.
Signs and planets, in aspects sextile, quartile, trine, conjoined, or opposite; houses of heaven, with their cusps, hours, and minutes; almuten, almochoden, anabibazon, catabibazon; a thousand terms of equal sound and significance, poured thick and threefold upon the unshrinking Dominie, whose stubborn incredulity bore him out against the pelting of this pitiless storm.
At length the joyful annunciation that the lady had presented her husband with a fine boy, and was (of course) as well as could be expected, broke off this intercourse.
