they are given with the fingers; there is danger of this in using the 
balling gun and some foxes are killed in this way. 
THE STOMACH TUBE HAS ADVANTAGES 
It is an easy matter to pass a stomach tube in the dog. A form 
of speculum which is commonly used consists of a piece of wood of 
a size suitable for the size of the dog to be treated, with a hole large 
enough to permit the passage of the tube bored through the middle 
of the piece, and with the ends of the piece rounded to make a grip 
for the hands on each side of the mouth. More elaborate metal 
speculums of various types may be purchased from commercial houses. 
One advantage of the stomach tube in dosing dogs is that the animal 
does not taste the drug and is less disposed to vomit after the ad¬ 
ministration of some unpalatable substances. 
POULTRY 
Mass Treatment 
The relatively small value of individual birds and the large number 
commonly present has given the subject of mass treatments, as 
opposed to individual treatments with anthelmintics, & greater amount 
of interest and attention in connection with treatments for poultry than 
in connection with treatments for other kinds of animals. As a result 
there have been developed such methods as the use of a tobacco infus¬ 
ion in the feed for the removal of roundworms from the small intestine, 
and the subsequent modification of this method in the use of tobacco 
dust in the feed for a considerable period of time. In the same way, 
a small amount of lye added to a cooked mixture of wheat and oats 
has been proposed for the treatment of tapeworm infestations in 
poultry. 
INDIVIDUAL TREATMENTS 
For individual treatments, birds may be drenched by means of a 
medicine dropper or drugs may be given by means of a stomach tube, 
a small human catheter serving as a tube. Dr. Bernard Gallagher 
tells me that a glass funnel or a pipette, with or without a rubber 
bulb, may be used to give drugs to fowls, the stem of the funnel or 
the pipette being passed to the crop or part way down the esophagus.
