4 ATLAS OF BIOLOGY. 



FIGS. X., XI., XII. Three sections, taken in order through the planes indicated by 

 the vertical lines in Fig. IX. 



Figs. XI. & XII. are especially designed to show the mode of attachment of the 

 viscera, the reflections of the peritoneum being indicated by a thick line. 



All are drawn as seen from behind, and the sub-cutaneous lymph-spaces, ly., are 

 indicated in black. 3. x 3. 



FIG. XIII. Dissection from the left side, to show the general disposition of the viscera, 

 and the neural canal with the cerebro-spinal axis.* 



Proceeding as for Fig. IX., the mesentery was next removed along the line c.mg'., and 

 with it the renal and reproductive organs of the left side those of the right, together with 

 the lung of that side, being seen through the mesentery. The alimentary canal was pinned 

 down and the large intestine opened up ; the tongue is figured thrown forward in prehension. 



The axial skeleton is here drawn in median longitudinal section. 3 x 2.
