His studies were also under the additional disadvantage, that, being pursued for the gratification of a desultory longing after knowledge, and directed to no determined object, they turned on points rather curious than useful, and while they served for the amusement of the student himself, promised little utility to mankind at large.
Bewildered amid abstruse researches, metaphysical and historical, Mr.
Cargill, living only for himself and his books, acquired many ludicrous habits, which exposed the secluded student to the ridicule of the world, and which tinged, though they did not altogether obscure, the natural civility of an amiable disposition, as well as the acquired habits of politeness which he had learned in the good society that frequented Lord Bidmore's mansion.

He not only indulged in neglect of dress and appearance, and all those ungainly tricks which men are apt to acquire by living very much alone, but besides, and especially, he became probably the most abstracted and absent man of a profession peculiarly liable to cherish such habits.

No man fell so regularly into the painful dilemma of mistaking, or, in Scottish phrase, _miskenning_, the person he spoke to, or more frequently enquired of an old maid for her husband, of a childless wife about her young people, of the distressed widower for the spouse at whose funeral he himself had assisted but a fortnight before; and none was ever more familiar with strangers whom he had never seen, or seemed more estranged from those who had a title to think themselves well known to him.

The worthy man perpetually confounded sex, age, and calling; and when a blind beggar extended his hand for charity, he has been known to return the civility by taking off his hat, making a low bow, and hoping his worship was well.
Among his brethren, Mr.Cargill alternately commanded respect by the depth of his erudition, and gave occasion to laughter from his odd peculiarities.

On the latter occasions he used abruptly to withdraw from the ridicule he had provoked; for notwithstanding the general mildness of his character, his solitary habits had engendered a testy impatience of contradiction, and a keener sense of pain arising from the satire of others, than was natural to his unassuming disposition.
