Although these results can not be considered as final, it is believed that 

 for the purpose for which this work was undertaken results have been 

 obtained which are of sufficient accuracy. It is, however, desirable that 

 further work be done by a method better adapted to the nature of the 

 liquid investigated. In future work greater precaution should be taken 

 to prevent the fat from being removed from the samples before the den- 

 sity determinations are made, and it would be very desirable if the per- 

 centage of fat in each sample could be redetermined after the density 

 determinations have been made. As these results were obtained with 

 mixed milk it would also be desirable to compare the density of milk in 

 different breeds of cows and the variation within the breeds.
