MAMMALIAN ANATOMY 
( b ) Columnar: (i) Transverse sections of the stomach 
and gastric diverticula of a grasshopper; (2) Trans¬ 
verse sections through some simple type of vertebrate 
intestine; (3) Sections through the mammalian 
oviduct. 
(c) Squamous: Surface mounts of the mesentery. (Cf. 
also serosa in the transverse sections of vertebrate 
intestine.) 
2. Stratified epithelium: 
(a) Cuboidal: Sections of larval amphibian skin. 
( b ) Columnar: Sections of oesophagus of lungless sala¬ 
mander (Desmognathus, Eurycea). 
(c) Squamous: (1) Sections of adult amphibian skin, 
unpigmented region (Desmognathus, Eurycea) show¬ 
ing also simple alveolar glands; (2) Surface mounts of 
moult layer of adult amphibian skin; (3) Sections 
of human fetal skin; (4) Sections of lining of mouth 
of some mammal; (5) Sections through mammalian 
oesophagus. 
C. Skeletal tissues.

1. Tensile varieties. 
(a) Loose: (1) Use sections of various organs such as 
intestine; (2) Adipose tissue of mesentery, surface 
mounts of thin regions. 
(. b ) Dense: (1) Longitudinal and transverse sections of 
tendons; (2) Teased preparations, longitudinal, and 
transverse sections of elastic ligament (ligamentum 
nuchae). 
2. Rigid varieties. 
(а) Cartilage: (1) Sections of hyalin cartilage; (2) Sections 
of elastic cartilage; (3) Sections of fibro cartilage. 
(б) Bone: (1) Transverse sections through the decalcified 
shaft of a long bone; (2) Transverse sections of dry human 
bone (shaft of long bone); (3) Longitudinal sections of dry 
human bone (shaft of long bone); (4) Longitudinal sec¬ 
tions of growing bone (end of a long bone).
