ABSORPTION THROUGH SKIN THORACIC DUCT. 199 



considerable amount. Thus there is a case recorded by Dr. 

 Currie, of a patient who suffered under obstruction of the 

 gullet, of such a kind that no nutriment, either solid or fluid, 

 could be received into the stomach ; and who was supported 

 for some weeks by immersion of his body in milk and water, 

 and by the introduction of nutritive liquids into the lower 

 end of the intestine. During this time, his weight did not 

 diminish ; and it was calculated by Dr. Currie, that from one 

 to two pints of fluid must have been daily absorbed through 

 the skin. The patient's thirst, which had been very trouble- 

 some previously to the adoption of this plan, was removed by 

 the bath, in which he experienced the most refreshing sensa- 

 tions. It is well known that shipwrecked sailors and others, 

 who are suffering from thirst owing to the want of fresh 

 water, find it greatly alleviated, or altogether relieved, by 

 dipping their clothes into the sea, and putting them on whilst 

 still wet. 



221. From the receptacle into which the chyle, and a con- 

 siderable proportion of the contents of the lymphatics, are 

 delivered, a tube passes upwards in front of the spine (fig. 

 114) ; and this tube, called the Thoracic Duct, conveys these 

 nutritious fluids to the point where they are to be delivered 

 into the current of blood. This delivery takes place at the 

 angle where two great veins unite, a point at which there is 

 less resistance than in any other part of their walls. These 

 veins are the Jugular, which brings the blood from the neck, 

 and the Subclavian, which conveys it from the arm, of the 

 right side (fig. 122) ; on the left side there is a smaller duct, 

 which receives some of the lymphatics of the left side, and 

 opens into the blood-vessels at a corresponding point between 

 the left jugular and subclavian veins. 



Sanguification. 



222. The Chyle of Vertebrated animals, as taken-up by the 

 lacteals, may be regarded as blood in an early stage of its 

 formation, with a large excess of fatty matter. It contains 

 about 90 parts of water in 100 ; about 3J parts of albumen, 

 and the same of fat ; and about 3 parts of other animal and 

 saline matter. Its appearance and characters differ, according 

 to the part of the lacteal system from which it is drawn. If
