 – The six remedies which compose this group, possess such symptomatic affiliations amongst each other, that, in many respects, they seem to represent the shades of one and the same malady.
 – However, they are far from producing, in the same degree, under perfectly identical circumstances, the symptoms which have been classed under the head of common characteristics; nor are they in the same degree or indiscriminately, adapted to the diseases which we have just now named as corresponding to them.
 – In giving the history of  each drug, the physiological and pathological conditions upon which its use depends will be mentioned.
 – What I may affirm, however, even now, is, that it frequently happens that several among them may, in the same individual and in the same malady, be successively indicated.
 – This remark is, indeed, applicable to almost every one of the twenty groups which I have adopted.
 – The remedies of the Arnica group, which are truly sovereign in a large number of acute affections, occupy, moreover, (and more particularly those last named,) an important rank in the treatment of chronic maladies.
 – I ought to observe, however, first, that with the exception of spigelia and the magnetic iron, which constitute the transition-points between this group and the following, they exercise only a very limited action upon the osseous system; second, that their feeble power to alter the nature of the secretions, renders them almost entirely inefficacious in degenerations of tissues.
 – It is thus that, among cutaneous diseases, they only reach those which manifest themselves in the simple forms of erythema, phlogosis of the dermis or of the subcutaneous cellular tissue, pustules and colorless vesicles; or, lastly, the warts and callosities, which, as is well known, emanate from an excess of local secretion of the epidermis-matter, induced by some mechanical cause.*
 – The remedies of the Arnica group only respond to a small portion of the series of known cutaneous disorders.
 – It is among the symptoms of Mercurius and Sulphur that we have to look for its completion.
 – Let me state that, among cutaneous diseases, I include all those which, by their nature, are susceptible of invading every part of the organism, but the primary seat of which seems to be the skin.
 – From such considerations, upon which the contiguousness of my first three groups is based, emanates the line of demarcations which I draw between the members of the Arnica and those of the Bryonia group, whose action seems to me to proceed inversely to that of the former; that is to say, from the centre to the periphery, and not from the periphery to the centre.
 – Finally, it may be well to allude-to a few relations existing between the Zincum and Arnica group, which, perhaps, may be of use to practitioners.
