| Description | Slide shows a chart of the contraction of a dog's spleen using 'air-plethysmograph' technique.
There are seven lines in the graph, labelled top to bottom: 'auricle, ventricle, forearm, spleen, [_], [_], .01gram suprarenal capsule'.
Title below slide reads: 'Fig. 71 - Contraction of spleen of dog as the result of injecting extract of suprarenal capsule (.01gram) into a vein. The spleen volume was recorded by an air-plethysmograph, the lever of which soon reached the limit of its registering capacity owing to the great contraction of the organ. The plethysmogram of the fore limb shows expansion, which is either passive, or due to dilatation of the vessels of its muscles. The acceleration and augmentation of auricle and ventricle is well marked.'
Chart is also labelled 'dog, 11.5 kilos laid out'. |
