The curve relating oxygen consumption to a gradually increased temperature was found to be less steep than K rogh's curve in Chironomus anthracinus and to correspond with K rogh's curve in Lumbricillus rivalis and Pisidium casertanum. Webfrom Chironomus anthracinus were larger (mean length 65 /um, measuring 15 organisms) with many kineties; no buccal cavity was observable under light microscopy of the scanty material available. Living infected larvae of C. plumosus apparently retained the reddish color of the hemolymph, but they were very slow-moving and apparently mori-bund. nothing message cody
