598 GLOSSARY. JEJUNUM MANGE. 



JEJUNUM. The second portion of the small intestines between the 

 duodenum and ilium. 



KILOGRAMME, KILOMETRE. See Weights and Measures. 



KREATINE, KREATININE ; also CREATINE, CREATININE. Two crys- 

 talline substances, the first having more distinct alkaline qualities 

 than the second, found in the juice of flesh, and also in the urine ; 

 both seem, like urea, to be products of the decomposition of the 

 contractile fibre in the actions of the living body, and are azotised 

 principles. See p. 311. 



LACHRYMAL. Of or belonging to the tears. 



LARYNX. See Epiglottis. 



LICE. See Parasite. 



LIEBERKUHN'S GLANDS. Tubular glands found over the whole inter- 

 nal surface both of small and great intestines. 



LIGHTS. The same as lungs. 



LINE. The twelfth part of an inch in its ordinary acceptation ; but 

 Johnson, in his Dictionary, quotes from Locke that a line is the 

 tenth part of an inch. In this work it is used to express the 

 twelfth part of an inch. 



LIQUOR SANGUINIS. The blood apart from the blood- corpuscles : 

 that is, the blood consists of a vesicular part, or blood-corpuscles, 

 and blood-plasma, or the remaining fluid i. e., the liquor sanguinis. 



LITHIC ACID. The same as uric acid. 



LUNGS. Called "lights" in common quadrupeds; highly vascular 

 organs subservient to the change of the blood from venous to 

 arterial, composed of minute cavities into which the air of the 

 atmosphere enters, and having two sets of blood-vessels namely, 

 the bronchial arteries and veins destined for the nutrition, and 

 pulmonary arteries and veins concerned in the special function of 

 these organs. 



MAGGOTS. See Parasite. 



MALPIGHI, PYRAMIDS OF ; CAPSULES OF ; CORPUSCLES or GLOME- 

 RULES OF. The pyramids of Malpighi in the kidney are the coni- 

 cal bundles of uriniferous tubes in the medullary substance of the 

 organ which open by their apices into the calyces or caps of the 

 inf undibula ; the capsules of Malpighi are flask-shaped sacculi con- 

 nected with the minute tubuli uriniferi in the cortical substance 

 of the kidney ; the corpuscles of Malpighi belong to the ultimate 

 structure of the kidney, vascular tufts. Each corpuscle is suspended 

 by a short pedicle composed of its artery and vein, and lies within a 

 capsule ; the secretion takes place from the subdivision of the vein, 

 analogous to that of the bile from the twigs of the vena portarum. 



MAMMALS. Animals that suckle their young. 



MANGE. See Parasite.
