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 uitt'Hobular duct system; (;5) 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 aciuar parenchyma.
