 of the acini. Such continuity is described also by Bensley for many of 

 the islets in the guinea pig's pancreas. Bensley's studies have disclosed 

 these further points of relationship between the islets and the zymo-

genous parenchyma: Islets may be located (1) in the interlobular con- 

 nective tissue, but connected with the duct system; (2) in the lobules, 

 also unconnected with the acini (encapsulated), but directly connected 

 with the interlobular duct system; (3) in the lobules these include 

 the great majority and in connection with either acini or ducts or both ; 

 and (4) islets unconnected with either ducts or acini, both in the inter- 

 lobular connective tissue and in the acinar parenchyma.
