A trifling jealousy is, at times, to be observed amongst the natives, at the numbers of the English resident here; the former supposing that we have a monopoly of business, and drain the country of money. These false reasoners in political economy cannot comprehend that, in trade, obligations are mutual, and that for our goods we buy their produce, often at a ruinous price. All increase of population to a new and thinly-peopled country, like Buenos Ayres, just released from a disgraceful thraldrom, ought to be viewed as a benefit: the well informed know it to be so. The British medical practitioners at Buenos Ayres are--Drs. Leper, Dick, Oughan,[8] Jenkinson, and Whitfield: the two last are apothecaries. Drs. Leper and Dick are surgeons in his majesty's navy, and are allowed to be men of talent, and have good practice. [8] Dr. Oughan has returned to England, in the _Kingfisher_ packet: some eccentricities in the doctor's conduct occasioned the British consul to make application for his being sent home. A physician here is not so profitable a concern as in England: the guinea fee dwindles to a dollar per visit, though to a favourite doctor they make presents. Once, in London, I remember seeing thirty single guineas, for as many visits, lying upon a doctor's table, the result of a morning's work; and this was thought but little, to pay for house expences, carriage, &c. A Medical Board has been formed here, which, a short time since, examined into the qualifications of the different medical men, propounding questions which, I am told, would have puzzled Esculapius himself to answer. Two unfortunate Irishmen were caught in the trap, and forbidden to practise. Paddy, at no time, likes his talent to be depreciated: accordingly, one of them took up the pen, and wrote a long philippic; the other did not confine himself to this, but made use of language, in the full senate of medical sages, that consigned him to a dungeon for three weeks, and he was afterwards banished the country. A French doctor was suspended, for an error in the accouchement of a lady. There is a North-American doctor (Bond), and plenty of native ones.
