on specimens in the laboratory; this is followed by a tabulation of resis- 

 tivities determined on the same group of rocks in situ. The remaining 

 tabulations give resistivities of consolidated and unconsolidated sedimen- 

 tary rocks, determined in the field, and of oil bearing formations, most of 

 them measured by electrical logs.
