IV. ABSTRACT OF PROCEEDINGS. 



October 8th, 1917. 



Mr. W. T. Wellington in the Oliair. 



Dr. H, G. Chapman gave a lecture upon "The Cold Trans- 

 port of Milk and the Preservation of Infants' Lives.'* This 

 was illustrated by exhibits, experiments and lantern slides. 



After demonstrating the substances in a pint of cow's 

 milk, the lecturer proceeded to consider the changes which 

 they might undergo through the activity of bacteria. The 

 acid curdling and the sweet curdling were thus dealt with, 

 and this led to the consideration of the dirt contained in it. 

 By means of cultures on gelatine plates, Dr. Chapman 

 showed the relative number of bacteria found in Sydney 

 milk when brought from the country, and when supplied by 

 suburban dairymen. The immensely greater number in 

 country milk caused the lecturer to emphasise the need for 

 cooling country milk previous to its long journey to the 

 city. He concluded, by showing, from mortality tables that 

 the chief cause of the deaths of infants between the ages 

 of 3 and 6 months was from diseases of the alimentary tract, 

 which are generally brought about by bad milk. The milk 

 of the city companies should be continually examined by a 

 competent bacteriologist. 



A discussion was contributed by Drs. Cleland and Ward- 

 law, Messrs. L. Meggitt, A. D. Olle, A. E. Stephen, 

 S. E, Sibley, G. I. Hudson, Irwin Ormsby, the Chairman 

 and the Hon. Sec.
