Preliminary Study of Mycetozoa. 



As a preliminary to the study of slime moulds, as suggested in the article of 

 T. H. MacBride'^^ reviewed in the September number of this Journal, a modi- 

 fication of the method given by Caspar O. Miller^ ^^ may be of interest, especially 

 as by it slime moulds in all phases of development can be obtained at any season 

 desired, and in such a form as to be suited to study in the laboratory. 



Miller discovered that plasmodia were developed in all cultures made by 

 filling a beaker half full of hay and covering the hay with ordinary tap water. 

 Care must be taken to allow some of the stalks of hay to project above the water, 

 to serve as a support upon which the plasmodia may climb. The beaker was 

 covered with a cotton plug to prevent the dust in the air from entering. The 

 ordinary moulds which appear after a few days were removed with sterilized 

 forceps, care being taken to loosen the under layers of hay, so that some of the
