 will scarcely be referred to, as we wish to narrow 

 the question in dispute down to its simplest issues. 

 We will, now, only state that early in the following 

 year an accomplished chemist, M. Pasteur, entered the 

 field, and henceforth became the most prominent ob- 

 jector to the doctrines of heterogeny. Although many 

 others have taken part in the contest, still it was, for 

 a long time, in 'the main carried on between M. Pasteur 

 on the one hand (backed by the immense moral support 

 of the French Academy) and. by MM. Pouchet, Joly, 

 and Musset, on the other. Most valuable experimental 

 evidence was, however, adduced in 1862 in support 

 of the possibility of the origin of living things from 

 not-living matter, by Professor Jeffries Wyman of 

 Cambridge, U.S., and in 1868 by Professor Cantoni 

 of Pavia.
