PLATE XLI. 
Fig. 1. The upper surface of the tongue of the Nubian Giraffe, with a portion of the 
integument removed, to show the superficial longitudinal and deep-seated 
transverse muscular fibres of the anterior prehensile part of the tongue; the 
perpendicular fibres are principally situated at the sides. 
2. The under surface of the same tongue dissected and injected, to show: aa. The 
stylo-glossi muscles. bb. The hyo-glossi. cc. The lingualis inferior. d. The 
genio-glossi. e. The transverse fibres of the muscular tissue. ff. The thin 
layer of transverse muscular fibres reflected from the stylo-glossus muscle, 
the lingual vessels and nerve, which it embraces. g. The nerve. hh. The 
venous plexus. 7. The lingual artery. k. The principal anastomosis, with 
the artery of the opposite side. /. The continuation of the left lingual artery,

This figure was drawn on the stone without the use of the mirror. 
3. The anterior extremity of the same tongue, showing the retroverted, pointed, 
horny papille on its dorsum, and the spherical gustatory papille at the sides. 
Natural size. 
4. A portion of the rumen or first cavity of the stomach of the Nubian Giraffe,

5. A portion of the reticulum, or second cavity of the same stomach, showing the

PLATE XLII. 
Fig. 1. A posterior view of the fauces of the Nubian Giraffe: with the velum palati d 
raised to bring into view a, the base of the epiglottis, and bb, its two lateral 
deflected processes. The letters cc are placed upon the apices of the aryte- 
noid cartilages: e, levator palati; ff, tensor palati; gg, the tonsils. Natural 
size. 
2. The glottis and epiglottis of the Nubian Giraffe. Natural size. The letters indi- 
cate the same parts as in fig. 1. 
3. An anterior view of the fauces of the Nubian Giraffe ; a, the free margin of the 
epiglottis projecting into the mouth below the velum palati, d: gg, outline of 
the tonsils: hh, their excretory outlets.
