To return to _Bacillinum_, I consider this remedy as a powerful moderator of the muco-purulent secretion of consumption. While diminishing the secretion it modifies the auscultation; there is less thick sputum, the cavities are drier, the peri-tuberculosis congestion less intense. The clinical symptoms follow those of the auscultation; as the patient expectorates less he is less feeble, coughs less, gains strength, and regains his spirits; but the tubercle remains untouched. The peri-tuberculous congestion only is diminished, as one may observe with the naked eye when Koch's lymph is employed in the amelioration of lupus. The peri-tuberculous inflammation disappears; the skin seems healthy, but the yellow tubercle remains as it was, and the patient is still uncured. Such are the limits I assign to _Bacillinum_ in its action on consumption. Far more potent is the part played by _Bacillinum_ in non-tuberculous pulmonary affections, for the simple reason that the struggle is with a less redoubtable opponent. Ebersole, Young, Zoppritz, Burnett, James, Holmes, Jousset, Steinhauf have published cases of the cure of acute bronchitis, influenza diarrhoea, syphilitic eruptions, cystitis, ringworm of the scalp, nephritis, idiocy, retarded dentition, cretinism, gout, rheumatism, etc., with _Tuberculin_ or _Bacillinum_. If we wish to prescribe _Bacillinum_ successfully in non-tuberculous affections, we must observe, on auscultation, symptoms analogous to those which are perceptible in tuberculosis. The peculiar characteristics which indicate _Bacillinum_ for non-tuberculous maladies of the respiratory organs are, in my opinion, the two following: The first is _oppression_; the second, _muco purulent_ expectoration. These two phenomena show themselves always in the last stage of tuberculosis; that is to say, together with the products contained in the preparation of _Bacillinum_. _Dyspnoea resulting from bronchial and pulmonary obstruction caused by a super-abundant secretion from the mucous membrane is marvellously relieved by Bacillinum._ I put forward this fact, not on the evidence of a single isolated observation, but on that of several cases conscientiously studied. Such expectoration leads to the auscultation of sub-crepitant râles, sounding liquid and gurgling, having some analogy to the moist sounds of tuberculosis.
