368 DETAILED SYNTHESIS. 



tremity, situated in all parts of the skin, yet most nu- 

 merous in some parts. (See Fig. 109.) 



1133. THE COILED PART or THE PERSPIRATORY GLANDS 

 is CONSTRUCTED of secretory membrane only : the part 

 between the coil and the surface is lined with cells. 



1134. THE STRUCTURE OF THESE GLANDS INDICATES 

 their office to be twofold, as is the fact : to remove water, 

 and to eliminate a viscid substance composed of mate- 

 rials no longer fit for use in the body. 



1135. THESE GLANDS REMOVE WATER in small quan- 

 tity to assist in removing the viscid substance, but in 

 large quantities when the heat of the body is excessive, 

 in order that by evaporating from the surface, the skin 

 and consequently the body may be cooled. 



1136. THE ELIMINATION OF THE VISCID SUBSTANCE 

 varies in quantity, independently of the watery, but in 

 accordance with the necessities of the Blood, a diurnal 

 increase taking place about midnight, commencing earlier 

 and continuing longer in infancy. 



1137. Remark. THIS PERIOD CORRESPONDS to the night-sweats of 

 some kinds of disease, that are merely extraordinary conditions of a 

 healthy, increased action. 



1138. Ittus. A ROOM IN WHICH A PERSON SPENDS THE HOURS OP 

 NIGHT will be charged with a greater quantity of, and much more un- 

 pleasant, exhalations, than will be found under like circumstances in the 

 day-time, though if a person remains awake the increase of perspiration 

 will not be as considerable as if he sleeps ; and the discomfort following 

 a sleepless night is partly owing to this fact. 



1139. Inf. THE MORNING is THE APPROPRIATE TIME to cleanse the 

 skin ; the clothing worn next the skin during the night should not be 

 worn during the day, but aired ; the bedding should be well aired every 

 morning, and often thoroughly cleaned ; sleeping rooms should be well 

 ventilated during the night, and thoroughly aired every morning. 



1140. Remark. It is NOT STATED that thorough washing of the 

 skin is absolutely necessary every morning ; it may be sufficient to do 

 this two or three tunes per week : but to rub the skin with a towel 

 every morning will not only do no harm, but will do much good.
