But then it should be remembered, in abatement of all this, that the symptoms of disease, in all the three cases which I have alluded to, as occurring in the family with which I was connected, were very much alike; whereas neither the mother nor the child had suffered, prior to the sickness, for want of sleep. Must we not, therefore, look for some other cause? Or if it is to be admitted that sleeplessness is exceedingly debilitating in its tendencies, must there not have been in addition some exciting cause still more striking? We will see. During the latter part of the autumn which preceded our sickness, the water of the well from which we were drinking daily had a very unpleasant odor, and a fellow student and myself often spoke of it. As it appeared to give offence, however, we gradually left off our remarks and complaints about the water, and only abstained, as much as we could conveniently, from its use. In the progress of the autumn, the well became nearly dry, and the offensive odor having become troublesome to others no less than to ourselves, it was very wisely concluded to draw out the water to the bottom, and thus find and remove the impurities. The task was exceedingly trying, but was at length accomplished. Besides other impurities, there were found at the bottom of the well, several toads in a state of putrefaction, and so very offensive that it was difficult to approach them, or even to approach the top of the well that contained them. They were of course removed as soon as possible, and every practicable measure was adopted which was favorable to cleanliness. This final clearing of the well was about two months before the sickness commenced. Now whether there was a connection between the use of this water and the sickness which followed, is a curious, and at the same time, a very important question. Against this belief, at least apparently so, is the fact that our disease resembled in no trifling degree, the prevailing disease in certain neighboring towns. Another fact is also worthy of consideration. The rest of the family drank freely of the water, why did not they sicken as well as we? But as a deduction from the force of these facts, it is to be observed that nobody else around us for several miles had the prevailing epidemic unless it was ourselves. And then as to the objection that only a part of the family sickened, it is to be recollected that in the case of some of them who sickened there might have been, nay, probably were, other debilitating causes in operation previously, to prepare the way; such as, for example, in my own case, the want of sufficient sleep.
