The Diatoms to be found around us are numerous and 

 beautiful. The preparation and study of these fascinating 

 little plants give us some idea of the marvellous design in 

 nature and test out our microscopes as no other common 

 forms do. To watch the motion and study the structures of 

 these forms is a continuous pleasure. The list we give here 

 includes the forms taken at Ningpo years ago and published 

 in Fauvel's notes on Chinese plant and animal life.
