   {\bf Solution:} They can be obtained by introspecting the theorem.\smallskip
 
   To introspect a theorem, let us define the following three functions that 
-  analyse the @{ML_type proof_body} data-structure from the structure 
+  analyse the @{ML_type_ind proof_body} data-structure from the structure 
   @{ML_struct Proofterm}.
