the mu mus clea cles was then tested and they were found to have a contractile power much les less than normal and la in re hect resembled muscles in a pro bounced pounced state ot of ra fatigue tigue thia this result was probably due to the removal of carbohydrate from the muscles rather than to a mysterious lou specific action ot of the ithe drug thi this conclusion wai was by another experiment
