PHYSIOLOGY: PRACTICUM III: PLATE VI. 



THORAX OF THE CAT OPENED ON THE RIGHT SIDE. 



The parietes were removed by incisions along the interrupted lines shown on Fig. 2. 



The first RIB and its CARTILAGE are entire ; the curved, interrupted line upon them 

 indicates approximately the outline of the CEPHALIC LOBE of the LUNG. The other 

 ribs and cartilages are transected ; the cut ends of the latter are left blank, of the former 

 dotted. 



The LUNGS were filled with alcohol and have therefore nearly their natural size. 

 The ventricular portion of the HEART is seen covered by the PERICARDIUM and partly 

 overlapped by the lungs.
