ong thecases included In this series se\eral in-stances are present where the consolidationsoccurring in children followed this course(Fig. 6). To say that this is the only coursefollowed in children is manifestly wrong.In ^•iew of the many existing cases of hiluspneumonia previously cited In the litera-ture. It Is also unmistakably true thatmany cases do occur in adults in which theconsolidation starts In the hilus region andspreads toward the periphery. While It ispossible that In adults, certain cases mayexist in which consolidation starts In theperiphery, we have never encountered onein which this relationship could be estab-lished. Masons explanation of the failureto elicit certain physical signs is probablyquite correct In certain Instances. It isalso true that a similar obscurity Inphysical signs can occur when the con-solidation is confined to the hilus region, inso-called hilus or root pneumonia, and it is 356 A Study of L(>bar Pneumonia and Its Piilinonary Complications

Furthermore, from theplates which have been shown of lobarpneumonia in adults, it is evident that, inthe greater number of instances, lobarpneumonia starts as a central consolidationin the hilus region and spreads peripher-ally. It would seem, therefore, that, atleast in the majority of instances, our oldconception of lobar pneumonia was thecorrect on
