 catheter may be inserted into a 

 rubber bulb having one opening. 

 Just sufficient air should be ex- 

 pelled from the bulb, so that the 

 dose of medicine will be sucked

 much air. The bird's head is 

 then brought in a line with the 

 neck, which is extended, the 

 catheter is passed carefully to the 

 crop, when a slight pressure on 

 the bulb forces out the medicine, 

 and the instrument is withdrawn. 

 The operator should be sure that 

 he avoids the trachea. 



For the treatment of the heter- 

 akis, Megnin recommends mix- 

 ing santonin with the food given 

 to the fowls. The powdered 

 santonin may be incorporated 

 in a cake, the dose being 7 or 8 

 grains for each bird. An efficient 

 remedy is made by boiling an 

 ounce each of male fern, tansy 

 and savory in a pint of water. 

 The resulting liquid is mixed 

 with flour, which is then made
