At, or shortly after dark, take as many 

 bottles as may be desired to the ward or dormi- 

 tory. Slightly damp the forearm (or the calf) of 

 the patient, and, turning the bottle right side up, 

 let the patient's arm rest upon the mouth of the 

 bottle (Fig. 28a). 



In from a few minutes to half-an-hour or 

 more the bottle will be noticed to have splashes 

 of blood upon the bottom and sides (in the case 

 of Anophelines only). If possible wait till all the 

 Anophelines have fed. 



Remove the bottle, invert upon a table, untie 

 the twine, and remove the netting. Replace the 

 bottle upon the prepared stopper.
