ORIGINATION OF LIVING BEINGS. 79 



So that M. Pasteur arrived at last at the clear and 

 definite result, that all these appearances are like the 

 case of the worms in the piece of meat, which was re- 

 futed by Redi, simply germs carried by the air and 

 deposited in the liquids in which they afterwards ap- 

 pear. For my own part, I conceive that, with the 

 particulars of M. Pasteur's experiments before us, we 

 cannot fail to arrive at his conclusions ; and that the 

 doctrine of spontaneous generation has received a final 

 coup de grace. 



You, of course, understand that all this in no way 

 interferes with the possibility of the fabrication of or- 

 ganic matters by the direct method to which I have 

 referred, remote as that possibility may be.
