14. Section of the iutestiiio at the point of connection with the diverticula, in onler to show the arraugeiueut 



of the blood vessels and the subdivisions of the diverticula. This figure is taken at the junction and shows 

 the diverticulum as one chambered, and with a large blood vessel penetrating the diverticulum from the 

 outside. This blood vessel comes from the dorsal vessel. This and the following live figures are outline 

 drawings from slides, but the details of less importance are not filled in. ht. small vessels iu the vascular
