These patches, at' first small and circular, enlarge by extension in an ever 

 increasing radius fxom the original point of infection until they are up- 

 wards of 2 inches in diameter when they may coalesce with another ad- 

 jacent patch and so form laxge irregular shaped areas. 



Animals in low thriftless condition and young stock — calves and year- 

 lings—are most prone to attack and the affection never takes very serious 

 hold of well conditioned mature animals. The affection usually appears 

 first on the head and neck, the eyelids, nose and base of ears being the 

 most common seats, but it may spread from there to the root of the tail 

 and other pajts of the body. 



Treatment. — Ringworm is not difficult to cure if, along with the local 

 treatment, an improved diet, and greater attention to skin cleanliness and 

 grooming are given. A pint of boiled linseed jelly is a useful addition to 

 the dailv feed while the calves are undergoing treatment. The best local 

 treatment is the daily application, of an oleaginous paraciticide ointment 

 after the scurf has been removed by means of scrubbing with soft soap and 

 scraping with a spoon or blunt knife. This removal of the scurf is 

 essential to success for otherwise the ointment has no chance of coming in 

 contact with the living fuagus causing the disease. Two of best ring- 

 worm ointments are red mercury (binidide) ointment or blue mercurial 

 ointment, which may be applied on alternate days, but they are both highlv 

 poisonous and therefore require exceptional care in use. Milder and 

 scarcely less effective applications are : — 



(a) Lard, 5 parts; lod., i part. [b] Soft soap, ^ parts; Sulph., i part. 

 [c] Glycerine, 3 parts; Sulphuric acid, i part. [d] Glycerine, 3 parts; Acetic 

 acid, I part. 



The ointment should be well rubbed in and the parts should 

 always be washed before a second application. The disease is contagious 

 and, as will be readily understood, the walls fences posts woodwork and 

 floors of the pens and paddocks are easily contaminated and may remain 

 a source of contagion for months so that the disease will continue to be 

 troublesome unless effective measures for the disinfection of pens are 

 thoroughly carried out. Cleansing with carbolic solution and hot lime- 

 washing are most likelv to be effective to this end. 



Queeqslarid Mange. 



In 1888 Mr. Ed. Stanley, F.R.C.V.S., Government Veterinarian for 

 New South Wales, investigated a contagious form of skin disease then pre- 

 valent in Queensland and the Northern Districts of New South Wales, 

 Avhich has hitherto been known as Queensland Mange buf which he 

 designated as a contagious prurigo. In response to a request from me Mr. 

 Stanley very kindly placed his excellent report on the disease at mv dis- 

 posal and from the extracts which I now quote a good idea of the nature 

 of the disease may be gained. He says : — 



" This disease appears to have been known in the North for several 

 years, and to have attracted attention darly in 1887, in consequence of 

 spreading through the colonv ; this was during the prevalence of heavy 

 rains, and the disease disappeared with the cold weather. Last summer 

 it reappeared, and extended principallv through the coast districts, extend- 

 ing into New South Wales, so that now it is more widely spread and more 

 severe in character than was ever remembered before. It is a disease of the
