Daugeard found his green spore -bearing organism 

 ( Paibacillns niultis])orns) on the walls ol a culture llask 

 used tor the growth of irc^h-water alg:e, where it ni.ade a 

 felt of ver\- ^oug slender llexible hlainenls. He states 

 that it e^intains chloroph\ll distributed through the ^.iro- 

 toplasm The S])in-iferovis filaments may be l.iranched 

 'the spores are a distinct green. Its habitat is aunmg 

 fresh-water algie in the vicinit>' of Caen, brance. 



To the second section of his genus he would ad<l the 

 following forms, descril>ed by Klein: liacillus de Bary- 

 anus, B. Solinsii, B. Peroniella, B. macrosporns, and B 

 limosns.all of which arc siiorifcrous, the spores being 

 lilue-green. These spores are all said to be impregnated 

 wdth chlorophyll.

This paper describes the morphology and biolo.gy of 

 Bacillus cyaneofuscus, which was first tound causing 

 damao-e to'the glue of a gelatin factory and afterwards in 

 other places. " This microbe is also the cause, or at least 

 one of the causes, of a deterioration cpiite frequent m 

 Holland cheeses, especially those known as ' Ealam,' a 

 change which, under the name of 'blueing,' is much 

 dreaded by makers of these products." 



This organism belon.gs to the chromoparons group of 

 pigment-forming bacteria, i. e., it is itself colorless, but 

 excretes the pigment. The first form of the pigment is a 

 l>iue-greeii substance, which, under the microscope, ap- 

 pears as soliddiliie .spherites, mixed in wdth the bacteria.
