Comments p.147 right column 4th paragraph:”The volume of contents of both the upper large and lower large intestine are surprisingly high by this method [see bottom of link ]. There are two reasons probably for this. In vivo the colon length measured by the transintestinal tube (ref 45) gives shorter measurements than post mortem, e.g. 109 cm instead of 152 cm. [Investigators] may therefore reduce these figures by a factor of 109/152 and the resulting volumes are then 640 cm^3 for the upper large intestine and 730 cm^3 for the lower large intestine. Even these volumes are probably on the high side since the descending colon and the rectum are often empty the caecum may also be empty in the morning (ref 16).”
