136 ANATOMICAL TECHNOLOGY. 



must "be avoided, and in the other no more force should "be used 

 than will suffice to propel the water very gently. 



8. If the contained water is to be measured, the organ should he 

 "brought to the edge of the vessel, and the latter filled so that the 

 outlet of the organ may be carried over its edge. Then the contents 

 are to be carefully expressed into another vessel. In no case must 

 the organ be made to support the weight of the contained water. 



9. While full, the organ should be measured as to length, width 

 and height, and as to its girth at one or more points. 



§ 335. To measure the Volume of an Organ. — The following 

 method is proposed by Dr. H. P. Bowditch {1, 149) : " Plunge the 

 organ into a vessel already full, and measure the overiiow." 



Of course the fuU vessel must stand in a dish from which the 

 overflow may be collected, and the ordinary anatomical tray will 

 not answer. In some cases, therefore, the following method, though 

 less simple, may be more easUy adopted, and the result will be 

 almost equally exact : — 



Attach a cord securely to some part of the organ. Place it in a 

 vessel, and fill the latter with water. Then remove the organ by 

 means of the cord, and the amount required to fill the vessel wUl 

 represent the volume of the organ. In most cases, the space occu- 

 pied by the cord may be disregarded.
