ABSTRACTS OF THE PAPERS THAT WERE READ 



The " presumptive coli test " on unchilled waters : W. Par- 

 tridge, F.I.C. The author pointed out that if positive results are 

 ignored and negative results only considered, the ' presumptive B. 

 coli test ' often usefully Supplements the ordinary chemical analysis 

 of unchilled water. 



Notes on methods of analyzing oleaginous seeds and f ruits : 

 E. Richards Bolton. It is shown that the errors in the estimation 

 of oil in oleaginous seeds and f ruits (copra in particular) are due 

 rather to sampling than to actual analysis. Methods of sampling, 

 grinding and analysis were demonstrated to show that while the oil 

 in copra could be estimated with great accuracy by the methods 

 given, departure from the procedure would be liable to cause con- 

 siderable error.
