Fifth Annual Report. 23 
ous. Small clods, etc., were overturned in the search for 
Sporotrichum. Pot was freshly watered. About 50 apparently 
healthy bugs, roughly estimated. 
October 16 —Pot D, wet: Five apparently Sporotrichum bugs 
seen. Sixty living, roughly counted. Pot freshly wetted as in 
A and C, but much more liberally. 
October 16—Pot E, dry: Proportion of Sporotrichum-covered 
bugs to living about the same as in other pots, possibly one or 
two more with Sporotrichum, but lesser growth in dry pots 
makes rough estimate less accurate. Pot not watered. Sporo- 
trichum bugs were not removed from the pots. 
Pots examined again on October 31. Sporotrichum bugs left 
in pots as before on October 16. 
Pot A, wet: Still moist. Perhaps 12 bugs dead with charac- 
teristic Sporotrichum color, one at least dead with no mouldy 
covering. Numbers still living and active, but owing to clods, 
etc., in dirt, not easy to count. As many alive as dead, or more 
apparently. Pot watered again with distilled water. 
Pot B, dry: Some alive but more dead. Few of the dead 
ones shew the characteristic mould. Pot left dry 
Pot C, wet: Earth not very moist, cracked in pot. Hardly 
10 white bugs seen. Many, far outnumbering dead, alive and 
active, apparently in healthier condition than in dry pot B. 
Pot rewatered. , 
October 31—Pot D, wet: Conditions about the same as in 
C, except pure Sporotrichum bugs; hardly more than on Oc- 
tober 15. Earth still moist, but cracked somewhat; few live 
bugs and no Sporotrichum found in cracks below surface of 
soil. Pot rewatered more liberally than were others. 
Pot E, dry: Conditions resemble those in other dry pot, B. 
Many bugs alive, and lively enough when sun strikes them. 
Many dead without characteristic Sporotrichum growth. One 
or two with Sporotrichum-like covering. Pot left dry. 
November 16— Pot A, wet: Six bugs or so alive. About 40 
with the white growth. Pot rather dry, freshly moistened. 
November 16— Pot B, dry: Bugs all dead apparently, but 
none with white growth on surface of body. (One exception?) 
Pot left dry. 
' November 16—Pot C, wet: At least 12 living bugs, appar-
