480 SUMMARY OF CURRENT RESEARCHES RELATING TO 



form and colour, but that it might possibly be a form of Myxococcus 

 rubescens, which is a very variable species. 



He devoted special attention to the germination of the spores, and 

 followed it out in Myxococcus rubescens. After 3-4 hours they were 

 found to have increased in size ; then they passed through an oval to 

 a rod-shaped form. In this stage motion begins, and growth in length 

 continues. Further, he notes that germination takes place by a small 

 portion of the spore going through these stages more rapidly than the 

 rest of the spore. He compares these results with those of Baur and 

 Thaxter, and he gives his observations as to the influence of temperature 

 and media on the growth of the organisms. He also records a series of 

 observations on the development of the cystophore, stalk, and head.
