Section 93. The following table presents these bones in something

like their relative positions. A closer approximation to the state of the

case will be reached if the student will imagine the maxilla raised up

so as to overlie and hide the palatine and presphenoid, the

squamosal similarly overlying the periotic bone, and the jugal reaching

between them. Membrane bones are distinguished by capital letters.
