18S MICROSCOPIC FUNGI. 



have at least 2^000 species for a knowledge of 

 wliich the microscope is essential. If they thirst 

 for discovery, let them be assured that here also 

 the earnest worker is sm^e 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 Britisli 

 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.
