CONTAGIOUS DISEASE GERMS, 237

 identical ; and as we affirm them to be dynamically 

 different, so also we assume that under well devised 

 differential experiments, other signs of their specificity 

 may be brought to light, and for each sort of them a 

 definite genesiology be written." Athough many 

 objections have been raised to these and allied views, 

 they appear to be regarded with especial favour in 

 the Government Report. More than a dozen closely 

 printed pages have been devoted to an exposition of 

 Hallier's strange doctrines, and several of his draw- 

 ings have been repeated in the Introductory Report 

 by Dr. Burdon Sanderson. 



Figures of the supposed contagious microzymes 

 have been given, which refute themselves. The draw- 

 ing given by Dr. Sanderson in his Report (Fig. i, p. 

 232), and described as groups of particles in fresh 

 vaccine, conveys no idea of the actual appearance of
