188 MICROSCOPIC rUNGI. 



have at least 2^000 species for a knowledge of 

 which the microscope is essential. If they thirst 

 for discovery^ let them be assured that here also 

 the earnest worker is sure to meet with such 

 a reward. Or if they would acquaint themselves 

 with the manifestations of Divine power as deve- 

 loped in the most minute of created things^ let 

 them follow such observers as Tulasne and De 

 Bary^ and seek the ^^ why and the wherefore^^ of 

 the phenomena of mycetal life. 



If there should still be any hesitation whether 

 there is in this pursuit sufficient of the element of 

 variety^ for those who do not desire to pursue the 

 subject into its deepest scientific recesses^ to 

 render it available for them^ let them go to a 

 good public library^ such as that of the British 

 Museum^ and inquire for the large illustrated work 

 by Corda^ entitled ^^ Icones Fungorum/^ or the 

 more recent volumes by Tulasne (Selecta Fungorum 

 Carpologia)^ and examine the figures of microscopic 

 fungi in either of those works^ and decide for 

 themselves.
