And as the services of a physician are not always to be had in small country towns, a little experience in the use and application of simple articles to various diseases seems to be absolutely necessary. It was by the aid of a few of these and similar simple remedies, that we were enabled to preserve the health of the passengers of that ill-fated ship, the Anglo-Saxon. The following testimony has never, until the present time, been made public, and we would not now make use of it, were it not that we wish to show that there are men, and women too, that can appreciate our labors:-- "The undersigned, passengers in the Anglo-Saxon from Boston, feeling it a duty they owe to Dr. G. H. Dadd, surgeon of the ship, would here bear testimony to the valuable medical services and advice rendered by him to us, whilst on shipboard; believing his attendance has been conducive of the greatest benefit; at times almost indispensable, not only during the short passage, but also through the trying period subsequent to the wreck through all of which, the coolness and devotion to the best interests of his employers and of the passengers, exhibited by him, deserve at our hands the highest terms of commendation.

EARLE, ROSALIE PELBY, OPHELIA ANDERSON, HELEN C. DOVE, ELEANOR TERESA MCHUGH, JOHN HILLS, FRANCES BLENKAM, HARRIET PHILLIPS, LOUISA A. BIGELOW, EASTPORT, May 9, 1847." Notwithstanding this disaster, Enoch Train, Esq., of Boston, with a liberality which does him credit, appointed us surgeon of the ship Mary Ann, commanded by Captain Albert Brown; thus giving us a second opportunity of proving what we had asserted, viz., _that the emigrants might be brought to the United States in better condition, and with less deaths, than had heretofore been done_. It must be remembered that about this time the typhus, or ship fever, was making sad havoc amongst all classes of men, and many talented professional men fell victims to the dire malady. We left Liverpool at a sickly season, having on board two hundred persons, and were fortunate enough to land them in this city, all in good health. Several ships which sailed at the same time, bound also to different ports in the United States, lost, on the passage, from ten to twenty persons, although each ship was furnished with a medical attendant. Here, then, is a proof that our agents cure while others fail. PROPERTIES OF PLANTS.
