APARTMENTS AND FURNITURE. 185 



the latter case, if a quantity of liquid, such as 

 water, or melted wax, or even blood, were 

 thrown into the cavities of the heart by means 

 of a syringe, and if considerable effort were 

 made, the liquid thrown in would soon run 

 into all the large and small branches of this 

 hollow river channel, or apartment, and fill it 

 entirely ; and the amount it would contain, as 

 I have before intimated, would be in an adult 

 equal to three or four gallons. Or to make it 

 perfectly plain to all, it would be equal to a 

 common sized pail full. 



Thus you see that though the apartment 

 of the circulation is strangely irregular, it is 

 nevertheless a very spacious apartment ; al- 

 most if not quite equal to the whole cavity 

 of the chest, in which the lungs and heart are 

 placed ; and not much inferior in point of size, 

 to the cavity below it, or that of the abdomen. 



But I must tell you here for I can now do 

 it something more of that part of the circula- 

 tory apartment which lies in the heart itself, or 

 in what may be called the little sea or lake into 

 which all these subterranean rivers constantly 

 pour their various crimson floods.
