Capsules may be given with the aid of a pair of round-tipped, 
blunt dissecting forceps. According to Dr. Gallagher, quite large cap¬ 
sules may be given to birds, but it is necessary to push these down 
the esophagus, preferably by means of a rubber tube. He also ad¬ 
ministers some drugs by means of an injection directly to the crop 
through the skin, using a hypodermic syringe, a method which has 
been reported by Ward and Gallagher in connection with the admin¬ 
istration of turpentine as an anthelmintic. Rectal injections are easily 
administered by means of an infant’s-size hard rubber syringe, the 
tip of the syringe being passed along the floor of the cloaca. The 
oviduct opens on the side of the cloaca and there is practically no 
danger of entering it. Rectal injections have been found effective in 
removing cecum worms.
