The situation of our medical brethren at Sunderland is most perplexing, and demands the kindest consideration on the part of the country at large; but let nothing which has occurred disturb the harmony so essential to the general welfare of that place, should their combined efforts be hereafter required on any occasion of public calamity. In truth both parties may be said to be right--the one in stating that the disease in question _is Indian cholera_, because the symptoms are precisely similar--the other that it _is not Indian cholera_, because it exists in Sunderland, and without having been imported--IN NEITHER COUNTRY IS IT COMMUNICABLE FROM ONE PERSON TO ANOTHER, as is now plainly shown upon evidence of a nature which will bear any investigation; and if blame, on account of injury to commerce, be fairly attributable to any, it is to those who, all the world over, pronounced this disease, on grounds the most untenable, a disease of a contagious or communicable nature. Let the Sunderland Board of Health not imagine that their situation is new, for similar odium has fallen _on the first_ who told the plain truth, in other instances--at Tortosa, a few years ago, the first physician who announced the appearance of the yellow fever, was, according to different writers, _stoned to death_; and at Barcelona, in 1821, a similar fate had well nigh occurred to Dr. Bahi, one of the most eminent men there--we need not, I presume, fear that a scene of this kind will take place in this country,--though the cries of "no cholera!" and "down with Ogden!" have been heard. One word as to observations regarding the needlessness of discussing the contagion question: the truth is, that the cleanliness and comfort of the people excepted, you can no more make _other arrangements_ with propriety, till this point be settled, than a General can near the enemy by whom he is threatened, till it be ascertained whether that enemy be cavalry or infantry.
