1900] CURRENT LITERATURE 281 
STIGMONOSE is the title of a bulletin by Albert F. Woods® in which he 
s fully his studies of the disease of carnations and other pinks, 
formerly called bacteriosis by Arthur and Bolley, and ascribed by them to 
the action of Bacterium dianthi. The preliminary statement by Mr. Woods 
ato the cause of the disease and the tone of his criticisms on Arthur and 
Bolley's work * were criticised by this journal *. Mr. Woods has now presented 
the evidence on which his conclusions rest, and it entirely justifies the sub- 
stance of his criticism. Moreover, the account of Arthur and Bolley’s work 
in the bulletin is full, and the defects in it are pointed out in a way to which 
no exception can be taken. 
Woods shows that neither fungi nor bacteria are present in the earlier 
siages of the disease, and though they may appear later, their presence is not 
shown repeatedly by colonizing aseptically these insects on carnations. As 
“bacteriosis” is misleading, stigmonose is suggested to replace it. Mr. 
Woods believes “that the insect injects some irritating substance of an acid 
a enzymic nature into the wound; that this substance causes the increase of 
ouidizing enzymes in the cells which it reaches, and that these enzymes 
interfere with the nutrition of the cell by destroying the chlorophyll and set- — 
ling up other changes which finally result in death.”—C. R. B.
