But the triumph of his enemies was not of long duration. In 1810 the Board was dissolved, and the control of the medical department vested in a director-general, with three principal inspectors subordinate to him. Then did Jackson return to active service, and from 1811 to 1815 was employed in the West Indies; his reports from whence embracing every topic relating to medical topography, to sanitary arrangements, and to the observed phenomena of tropical disease, are it is not too much to say, invaluable. His hints as to the choice of sites for barracks, the propriety of giving to soldiers healthy employment and recreation, as a means of averting sickness, his suggestions as to the treatment of fevers and other endemic diseases, may be found in the various works he has published, embodying the fruits of his West Indian experience.
In 1819, he was sent by government to Spain, where the yellow-fever had broken out, and his report upon its characteristics has been universally admitted to supply the fullest information on the subject that had hitherto been communicated to the public. He availed himself of his presence in that part of Europe to pay a visit to Constantinople and the Levant; and, retaining his energy to the last, when a British force was sent to Portugal in 1827, he desired permission to accompany it. The sands of his life, however, were then fast running out, and on the 6th of April in the same year he died, after a short illness, at Thursby, near Carlisle, in the 77th year of his age. Thus closed a long career of usefulness; for it is not too much to say, that few men of his time laboured harder to benefit his fellow-creatures than did Dr Robert Jackson.
THE MYSTERIOUS LADY
herpassing from suspicion and alarm to the most stubborn resolve. All this was somewhat ludicrous, because nobody really felt particular interest in her movements, or desired to pry into her actions; but on discovering what appeared to be the weak point in her characterbecause it was out of all proportion strongidle people, in search of amusement, availed themselves of the knowledge to lead her a very uncomfortable life. Her most intimate friends never knew, for months together, where she was to be found; and it was currently reported that General Jerningham had once advertised in the Times for his sister. Certain it is, she always conned the newspapers with avidity, particularly the portion devoted to anonymous communications and the mystical interchange of sentiments; and we frequently suspected that her interest arose from a deeper source than mere curiosity. The simple query: 'Where do you think of passing this autumn, Miss Jerningham?' threw her into a state of strange excitement; and she always commenced her answer somewhat in the following strain: 'Letters of importance, daily looked for, will determine mecircumstances over which I have no control: it is possible that I may visit Cowes;' but a possibility declared in this way by Miss Jerningham was never known to come to pass. Wherever she chanced to be seen, former acquaintances popped upon her with uplifted hands, exclaiming: 'What! you here? Why, we thought you were at Ilfracombe'or some other far-away place. 'How long have you been here?how long do you stay?' were questions easily parried; but if a more searching investigation commenced, then the Mysterious Lady turned, and twisted, and doubled painfully; but somehow always managed to elude and baffle her persecutors.
Miss Jerningham's moral rectitude and unimpeachable propriety of conductunsullied by the breath of detractionrendered her in a great measure impervious to downright ill-nature; but still she was open to teasing and bantering; and the more she was teased, and the more she was bantered, the more impenetrable she became. We endeavoured to find out from herselfbut unsuccessfullyif she had always led such a roving kind of existence, and also how it originated; for General Jerningham had a nice villa near the metropolis, and a small, amiable, domestic circle, ready to receive and welcome the wanderer. But no: she came upon them unawares, and at periods when they least expected her, and disappeared again as suddenly, they knew not why nor whither. In this way she vanished from the boarding-house where we first met her, with no intimation of her intention even to our hostess, till her baggage was ready and the coach at the door.
'Where is Miss Jerningham?' was the unanimous cry when she did not appear in her usual place.
'She left us early this morning,' quietly replied the landlady.
'Gonereally gone?' was repeated in various tones of disappointment; and one old gentleman, who had paid the absent lady marked attention, demanded in a chagrined voice: 'Pray, where has she gone? Can you tell us that , ma'am?heigh!'
'No, sir, I cannot,' replied our hostess. 'All I can say is, that Miss Jerningham is a very honourable and generous lady, and wherever she is, I wish her well.'
'Humph!' said the old gentleman gruffly; 'she must have a good fortune to do as she does.'
