Before leaving this part of the subject, it may be well to note certain cases, collected by Theodore Parker, of consumptive families, in which those members who were topers did not die of consumption. It appeared that, in certain families whose histories he gave, nearly all those who did not die of consumption were rum-drinkers! And from these data Mr. Parker drew the inference that "intemperate habits (where the man drinks a pure, though coarse and fiery liquor like New England Rum) tend to check the consumptive tendency, though the drunkard, who himself escapes the consequences, may transmit the fatal seed to his children." Mr. Parton, who quotes this, thinks it poor comfort for topers. We doubt if there is any "comfort" to be found in it. It is contrary to all our present science to suppose that consumption can be prevented by narcosis. The prime cause of consumption is defective assimilation: the tissues, _from lack of sufficient nerve-stimulus_, are incapable of appropriating food. How absurd, therefore, to suppose that narcosis, which impairs the stimulating energy of the nerves, can check an existing tendency to consumption! What the consumptive person needs is stimulus, not paralysis. But it is easy to believe that the same impaired nutrition of the nerves which may in one person end in consumption, may in another person act as a predisposing cause of narcosis. Insanity, consumption, and drunkenness, are diseases which appear to go hand in hand. Dr. Maudsley, in his great work on the "Pathology of Mind," gives instructive tables which show that these three diseases may alternate with each other in the same family for several generations, culminating finally in epilepsy, idiocy, paralysis and impotence, when the family becomes happily extinct. This consanguinity of diseases appears more marked when we extend our view over a certain extensive locality. The figures cited by Gov. Andrew appear to show that both drunkenness and insanity are far more common in New England than in other parts of the Union; and consumption is proverbially the New England disease. We are inclined to suspect, therefore, that in the families mentioned by Mr. Parker, the children inherited structurally defective nervous systems, the consequent symptoms being in one case pulmonary and in another case cerebral.
