We need not hesitate to put very great confidence in the opinion here expressed; for besides being a close and just observer of human nature, Dr. D. has had the direction and management, in a greater or less degree, of several thousands of new-born infants.
Nothing, indeed, in the whole range of physical education, seems better proved, than that while some few infants, whose constitutions are naturally very strong, are invigorated by the practice in question, others, in the proportion of hundreds for one, who are less robust, are injured for life; some of them seriously.
Nor will spirits added to the water make any material difference. I am aware that there is a very general notion abroad, that the injurious effects of cold water, in its application both internally and externally, are greatly diminished by the addition of a little spirit; but it is not so. Does the addition of such a small quantity of spirit as is generally used in these cases, materially alter the temperature? Is it not the application of a cold liquid to a heated surface, still? Can we make anything else of it, either more or less?
I do not undertake to say, that the cold bath may not be so managed in the progress of infancy, as to make it beneficial, especially to strong constitutions. It is its indiscriminate application to all new-born children, without regard to strength of constitution, or any other circumstances, that I most strenuously oppose. Of its occasional use, under the eye of a physician, and by parents who will discriminate, I shall say more presently.
