A Manometric Respirometer for Snails
1 Department of Zoology and Comparative Anatomy, University College, London
A manometric apparatus for studying the oxygen consumption of large land invertebrates is described. Essentially it is a "polymerized" Warburg manometer. Simplicity of construction and manipulation have been aimed at, the apparatus being intended for use where large numbers of routine measurements have to be made. The effectiveness of CO2 absorption is experimentally investigated, and factors limiting the sensitivity and accuracy of the apparatus are discussed.
