Abstract
A puzzle for identity statements using massnouns, central to the expression of chemicaltypes, arises if one accepts that both `Wateris H2O' and `Ice is H2O' are identitystatements, since they jointly entail that`Water is ice'. The puzzle is resolved if itcan be shown that the `is' of such statementsis not the `is' of identity.
