 decided, most apparent, however, in the arteries. At the same 

 time there is a marked acceleration of the blood-current, equally 

 pronounced in arteries, veins, and capillaries. The stage of

FIG. 95. 



Appearance when the velocity of the circulation is normal, a, axial column 

 of corpuscles, both red and white, in such rapid movement that individual 

 corpuscles cannot be distinguished. Occasionally a white corpuscle is thrown 

 from the axial mass and appears in the plasmic zone 6. 



FIG. 96. 



Appearance when the velocity of the circulation is moderately reduced. The zone 

 b contains numerous leukocytes.

Appearance when the current of blood is sluggish, a, red corpuscles, still in the 

 axis ; b, peripheral zone, containing leukocytes, d, and blood-plates, c. 



When stasis is fully established the red corpuscles also invade the peripheral zone. 

 The figures are from observations made on the vessels of a dog's omentum 



during life. 



acceleration in the blood-current will never last more than one 

 or two hours, by the end of which time the vessels have be- 

 come twice their normal diameter.
