"His manners and appearance at this period were winning and agreeable. Although only sixteen years of age, his figure, which had advanced to nearly its full stature, was no less distinguished for the elegance of its proportions, than its healthy manliness of character; his handsome and expressive countenance was illumined by the generous disposition and active mind, equally characteristic of him then as in after life; his conversation was brisk and animated, his voice and manner of address were in the highest degree pleasing and gentlemanly; while a soft and graceful ease, attendant on every action, rendered his society no less agreeable than his appearance prepossessing."--(P. 90.)
The period of his arrival in London had been of course fixed with reference to the opening of the professional season--viz. in the month of October, when the lectures on medicine, surgery, anatomy, physiology, and their kindred sciences, commence at the hospitals, and, in some few instances, elsewhere. Mr Cline's house was in Jefferies' Square, St Mary Axe, in the eastern part of the metropolis; and in that house Mr Astley Cooper afterwards began himself to practise. His propensities for fun and frivolity burst out afresh the moment that he was established in his new quarters; and for some time he seemed on the point of being sucked into the vortex of dissipation, to perish in it. He quickly found himself in the midst of a host of young companions similarly disposed with himself, and began to indulge in those extravagances which had earned him notoriety in the country. One of his earliest adventures was the habiting himself in the uniform of an officer, and swaggering in it about town. One day, while thus masquerading, he lit upon his uncle in Bond Street; and, finding it too late to escape, resolved to brazen the matter out. Mr Cooper at once addressed him very sternly on his foolish conduct, but was thunderstruck at the reception which he met with.
"Astley, regarding him with feigned astonishment, and changing his voice, replied, that he must be making some mistake, for he did not understand to whom or what he was alluding. 'Why,' said Mr Cooper, 'you don't mean to say that you are not my nephew, Astley Cooper?' 'Really, sir, I have not the pleasure of knowing any such person. My name is ---- of the --th,' replied the young scapegrace, naming, with unflinching boldness, the regiment of which he wore the uniform. Mr William Cooper apologised, although still unable to feel assured he was not being duped, and, bowing, passed on."--(P. 401.)
