This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1922 edition.

Our findings may not be accepted as conclusive evidence of the bactericidal power of true cod-liver oil, but at least they contain important suggestions to medical philosophers and important leads for the greater laboratories of the land, because: 1. In the manner in which they were used the cod-liver oils have had a definite inhibitory and bactericidal action on virulent tubercle bacilli; cotton-seed oil, used for control, has not inhibited the growth of the organisms to the same marked degree, and has shown no bactericidal action; tubercle bacilli cultivated on the cotton-seed oil media for six weeks were able to grow and produce tuberculosis, whereas tubercle bacilli cultivated on cod-liver oil media for the same length of time were not able to grow when transplanted or to produce tuberculosis in injected animals. 2. Under the same circumstances, cod-liver oil has also inhibited the growth of a lepra bacillus, an avirulent T. Be. and the B. Typhosus. 3. The aqueous extract of cod-livers has shown no true inhibitory or bactericidal action on the T. Be. Whether it has any attenuating property in the long run, comparable to bile, remains to be seen. 4. The most interesting and definite findings have been the increased granular appearance and granulation of the T. Be. and allied bacteria after contact with cod-liver oil, especially in view of the fact that similar changes have been observed in the bacilli from sputum of patients treated with sodium morrhuate.
