The return of the food from the rumen into the oesophagus is con- 
sidered to be caused by rarefaction of the air in the thoracic cavity.

The last named paper gives the principal general results arrived at. 
Various degrees of deciduation are distinguished, and the poly cotyledonary 
placenta of the Ruminaats is regarded as obliterating the line of de- 
marcation between the diffuse non-deciduate and the zonary deciduate 
types of placenta.
