SOME PBOBLEMS IN INFECTION AND 

 ITS CONTBOL-' 



I EXPERIENCE a high sense of honor on 

 this occasion with which is mingled no less 

 trepidation in view of the master in whose 

 memory this lectureship was founded, and 

 the great names that in the past have been 

 linked with the post I am to-day asked to fill, 

 I must believe that Huxley would have felt 

 a deep interest in the theme which I have 

 chosen to discuss before you and would 

 have found in its intrinsic importance a 

 compensation for any shortcoming that 

 may appear in the presentation. For 

 Huxley evinced a penetrating appreciation 

 of that branch of biological science that 

 has come to be called bacteriology, and as 

 president of the British Association in 

 1870 devoted the occasion of his address 

 to an illuminating examination of the doc- 

 trine of abiogenesis, or spontaneous gene- 

 ration, versus the doctrine of biogenesis or 

 descent from living ancestors. This sub- 

 ject, long holding a merely academic in- 

 terest, had become in the two decades im- 

 mediately preceding the ground over which 

 the conflict raged and out of which was to 

 emerge the modem science of microbiol- 

 ogy. While Huxley clearly pointed out 

 that Redi in the seventeenth century and 

 Spallanzani in the eighteenth had deliv- 

 ered the first telling blows that later, 

 through Pasteur, led to the overwhelming 

 defeat of the spontaneous generationists 

 and the establishment on an indisputable 

 basis of the extrinsic origin of the contag- 

 ious and infectious diseases, he did not fail
