In the case of Richard Martin, whose death occurred at Sunderland about two months ago--in the case of Martin M'Neal, of the 7th Fusileers, which occurred at Hull, on the 11th of August last--in the cases at Port Glasgow, as detailed in a pamphlet by Dr. Marshall of that place--as well as several other cases which occurred throughout the year, and the details of many of which are in possession of the Board of Health--the advocates, "_par metier_," of contagion in cholera, have not a loop-hole to creep out at. Take but a few of the symptoms in one of those cases as taken down by the Medical Gentleman in charge,--"The body was cold, and covered by a clammy sweat--the features completely sunk--_the lips blue_, the face discoloured--tongue moist and very cold--the hands and feet blue, cold, and as if steeped in water, like a washerwoman's hand; the extremities cold to the axillae and groins, and no pulse discoverable lower; the voice changed, and the speech short and laborious. He answered with reluctance, and in monosyllables." This man had the pale dejections, and several other symptoms, considered so characteristic of the Asiatic cholera; yet no spreading took place from him, nor ever will in similar cases. With the exception of the vomiting and purging, there is, in the state of patients labouring under this form of cholera, a great similarity to the first stage of the malignant fevers of the Pontine Marshes, and many other places, and the patient need not be one bit the more avoided. Let this be, therefore, no small consolation, when we find that, by the official news of this day, five more deaths have occurred at Sunderland. Nov. 9, 1831. LETTER VII.
