Another disease of unknown origin, consisting of ulceration of 
the cornea in cattle, which is believed to be epigootic, is also being 
investigated: 
Hetinomycosis, pleuro-pneumonia, “ cancers,” and other diseases 
in animals, have also received some attention. 
As instances of work of another character, I may mention the 
examination of filters and filtering materials as to their power of 
removing germs from drinking water, the testing of measures of 
disinfection, and a few other matters of general hygienic import- 
ance. ‘These are, as yet, incomplete. It was also attempted to

water supply, but owing to the lack of accommodation and the 
numerous demands in other directions the examinations have

the water is remarkably free from germs, and that those which 
occur are of a harmless nature, such as always exist in natural 
waters.

Cambridge University, and by Lindley. On his arrival in New 
South Wales, his official title was changed to that of Director. 
Mr. Moore found at this time that there were only a few trees 
planted in the upper and lower gardens, and that the gardens 
were stuffed with duplicate plants, and that none of the plants 
were labelled. During his directorship Mr. Moore superintended 
the work of reclaiming the lower portion of the gardens between 
Cunningham’s monument and the present wall around Farm 
Cove. and by dint of constant labour brought the gardens up to 
their present beautiful condition, which has made them famous 
throughout the world. Not only the Botanic Gardens, but the
