Fig. 61, Hinder view of the larynx and its arytenoideus muscles; the dotted outlines 
indicating the absent left thyroid cartilaginous moiety. Ar, arytenoideus; 
P.c.a, posterior crico-arytenoid. 
Fig. 62. Ventral surfaces, hyoid bones, thyroid and cricoid cartilages, and on opposite 
half the deep muscles connected therewith. H' and Hg’, separate insertions 
of hyoglossus; Me, fibres of middle constrictor ; Thy, thyroideus ; Cth, cri- 
cothyroideus. 
Fig. 63. Larynx and hyoidean arch, in profile. 7, thyroid cartilage; C, cricoid; tr, 
trachea ; c.t.l, crico-thyroid ligament ; /, lateral thyro-hyoid ligament ; sh, stylo- 
hyal, and ¢yh, tympanohyal, its cartilaginous articulating tip; eh, epihyal; 
cth, ceratohyal ; bh, basihyal ; th, thyrohyal. 
Fig. 64. View from behind of the hyoidean arch and larynx. A, arytenoid cartilage ; 
S, cartilage of Santorini; m, nodule in thyro-hyoid membrane. Other 
lettering corresponds with the parts in fig. 63, 
PLATE LXXXI. 
Fig. 65. Reduced view of the distended stomach, seen from behind, with the spleen, 
vessels, and nerves 7” situ: 
@, esophagus, cardiac end; py, pyloric end of stomach; d, duodenum ; sp, spleen; 
h.a, hepatic artery cut short; s.a, splenic artery; v.b, trunk of one of the vasa brevia ; 
c.a, cardiac artery; g.es, gastric epiploica sinistra as it proceeds to inosculate with the 
dextral branch. The veins not lettered follow alongside the arteries; n, gastric nerve 
other branches are seen distributed upon the surface of the stomach. 
Fig. 66. A few inches of the Jejunum, with the mesentery attached, and showing the 
intestinal subdivision and distribution of the superior mesenteric vessels: a, 
artery; v, vein. 
Fig. 67. Portions of the ileum and colon, with cecum coli and ramifications of the 
ileo-cxecal artery and vein: cw, cecum; a, artery; v, vein. The arrows indi- 
cate the passage from small to great gut. 
Fig. 68. Small piece of intestine (14 feet from pylorus), cut open to display part of 
broad elongated Peyer’s patch. Pgl. Peyer’s gland, about nat. size. 
Fig. 69. A portion of the rectum, exhibiting its mucous membrane, of nat. dimen. 
Fig. 70. A longitudinal section of the right kidney, sliced through a little to one side 
of its middle. Of nat.size. The arteries, veins, and urinary tubes have each 
different-coloured injection thrown into them. 7.a, renal artery; rv, renal 
vein; wu, ureter; * veno-arterial inosculations. 
Fig. 71. Segment of the cortical surface of the same kidney, showing the arborescent 
nature of its superficial vascularity. The darker stellate lines indicate chiefly 
the veins. The undulate marginal periphery exhibits but slight lobulation.
