94 VEGETABLE PARASITES. 



comb and wattles. Bathino- the favic area should be 

 done before any fungicide is employed, and if any 

 crusts can be removed, they of course should. The 

 diseased area then may be dressed with an ointment 

 made of one part of red oxide of mercury to eight 

 parts of lard well rubbed into the skin. 



Benzine, sulphur, and soft soap also forms a good 

 destroyer of this fungus — a few drops of the benzine 

 and just a sprinkling of flowers of sulphur mixed up 

 in an ordinary pill-box of soft soap or lard. With 

 either of these the bird should be anointed every 

 day. As a rule, in about a week all signs of the 

 favic cups have disappeared. Isolation of any diseased 

 bird should at once be carried out, and great care 

 should be taken in dressing the patient not to transmit 

 the affection. 



VI. Mycosis of Air-passages. 



As far back as 1815 Fungi were noticed in the 

 air-passages of various birds by Meyer and Emert. 

 These vegetable parasites seem common in many wild 

 birds and in all our domesticated ones. Rosseau was 

 the first, in 1841, to note this malady in Poultry. 



Cause of Mycosis. 



The mycosis of the air-passages, and even the air- 

 sacs, is caused by ' Moulds/ Mucedince, belonging 

 to the genus Aspergillus, fungi that are endowed 

 with great vegetative qualities.
