Contain a description of the principal modifications of the 
mouth, tongue, salivary glands, alimentary canal, liver, and 
pancreas of the various groups of mammals, illustrated with 
forty woodcuts. Particular attention is given to the form of the 
liver, and a new arrangement of the lobes and fissures of this 
organ proposed, by which the homologous parts are readily 
recognized and described throughout the series. In the typical 
mammalian liver the principal lobes are named left later dl, left 
central, right central, right lateral, sjngelian, and caudate, and 
the fissures the portal, umbilical, left lateral, right lateral, and 
caudate. Among other new points the liver of the gorilla is 
shown to differ from that of the other anthropoid apes in having 
well-marked lateral fissures, as in the lower monkeys : also a 
parotid salivary gland in the seal is described.
