"But," says Doctor Holmes, "we deceive ourselves by names, if we suppose the frozen part to be treated by cold, and not by heat. The snow may even be actually warmer than the part to which it is applied. But even if it were at the same temperature when applied, it never did and never could do the least good to a frozen part, except as a mode of regulating the application of what? of heat. But the heat must be applied gradually, just as food must be given a little at a time to those perishing with hunger. If the patient were brought into a warm room, heat would be applied very rapidly, were not something interposed to prevent this, and allow its gradual admission. Snow or iced water is exactly what is wanted; it is not cold to the part; it is very possibly warm, on the contrary, for these terms are relative, and if it does not melt and let the heat in, or is not taken away, the part will remain frozen up until doomsday. Now the treatment of a frozen limb by heat, in large or small quantities, is not Homœopathy."

Another supposed illustration of the Homœopathic law is the alleged successful management of burns, by holding them to the fire. "This is a popular mode of treating those burns which are of too little consequence to require any more efficacious remedy, and would inevitably get well of themselves, without any trouble being bestowed upon them. It produces a most acute pain in the part, which is followed by some loss of sensibility, as happens with the eye after exposure to strong light, and the ear after being subjected to very intense sounds. This is all it is capable of doing, and all further notions of its efficacy must be attributed merely to the vulgar love of paradox. If this example affords any comfort to the Homœopathist, it seems as cruel to deprive him of it as it would be to convince the mistress of the smoke-jack or the flatiron that the fire does not literally draw the fire out, which is her hypothesis.

"But if it were true that frost-bites were cured by cold and burns by heat, it would be subversive, so far as it went, of the great principle of Homœopathy. For you will remember that this principle is that Like cures Like, and not that Same cures Same; that there is resemblance and not identity between the symptoms of the disease and those produced by the drug which cures it, and none have been readier to insist upon this distinction than the Homœopathists themselves. For if Same cures Same, then every poison must be its own antidote,—which is neither a part of their theory nor their so-called experience. They have been asked often enough, why it was that arsenic could not cure the mischief which arsenic had caused, and why the infectious cause of small-pox did not remedy the disease it had produced, and then they were ready enough to see the distinction I have pointed out. "O no! it was not the hair of the same dog, but only of one very much like him!"

The belief in and employment of the "Infinitesimal doses," Doctor Holmes handles with the same fairness and acumen; but the absurd idea affirmed by Hahnemann that Psora is the cause of the great majority of chronic diseases, he treats as it deserves, with unqualified contempt.

In conclusion, he says, "As one humble member of a profession which for more than two thousand years has devoted itself to the pursuit of the best earthly interests of mankind always assailed and insulted from without by such as are ignorant of its infinite perplexities and labors, always striving in unequal contest with the hundred armed giants who walk in the noonday and sleep not in the midnight, yet still toiling not merely for itself and the present moment, but for the race and the future, I have lifted up my voice against this lifeless delusion, rolling its shapeless bulk into the path of a noble science it is too weak to strike or to injure."

Upon the contagiousness of Puerperal Fever, Doctor Holmes wrote an able treatise some forty years ago. This was reprinted with some additions, in 1855, and in an introductory note which accompanies the still later addition (1883), Doctor Holmes says, "The subject of this Paper has the same profound interest for me at the present moment as it had when I was first collecting the terrible evidence out of which, as it seems to me, the commonest exercise of reason could not help shaping the truth it involved. It is not merely on account of the bearing of the question—if there is a question—on all that is most sacred in human life and happiness that the subject cannot lose its interest. It is because it seems evident that a fair statement of the facts must produce its proportion of well-constituted and unprejudiced minds."

The essay, a most valuable one, is republished without the change of a word or syllable, as the author upon reviewing finds that it anticipates and eliminates those secondary questions which cannot be for a moment entertained until the one great point of fact is peremptorily settled.

There are but very few subjects, indeed, in medical science, that Doctor Holmes has not investigated, and investigated, too, most thoroughly....

In his article on "Reflex Vision," published in Volume IV. of the Proceedings of the American Academy, will be found a very interesting account of his experiments in optics. One, indeed, that will both interest and instruct.
