In the anterior half ofthis course the nerves lie well under the overlapping lip of the riband often have to be hooked out to be brought into view, in theposterior half of this course they are not so deeply situated and arereadily seen Upon opening the intercostal spore. The twelfth intercostal unlike the other intercostals graduallydraws away from the rib so that at about the tip of the twelfth rib.
