the fact that F. Wagner in his Presshefe und Garungsalkohole, 1914-1935, 

 lists a little over 1 ,800 patents. 



And so I come to the end of my matters. Much of interest has had 

 to be omitted, as for example the relation of entomogenous fungi to insect 

 epidemics, and the utilisation of cellulose material, and it has not been 

 possible to develop any aspect of the subject in the manner of many of 

 my predecessors, who reviewed philosophically tendencies of the 

 past or speculated on future progress. What of the future ? Though 

 a fairly large number of fungi have been investigated they form a very 

 small percentage of the total, of which we have yet no idea of the probable 

 limit. The possibilities for practical results are endless, and the processes 

 carried out by these strange organisms are pregnant with probabilities. 

 To some it is of interest to know what an organism is, to others to know 

 what it does and to others how it does it. Here we have a field in which the 

 taxonomist, the chemist and the physiologist can work together profitably 

 in the cause of science — which is the good of humanity.
