The author describes a survey of bacteriological methods of State laboratories throughout the country which was made in the interest of increasing the accuracy and dependability of milk analysis. Survey forms were used and included one for the agar plate method, and one for the direct microscopic and methylene blue reduction methods. The U. S. Public Health Service survey forms should be of value to administrators in improving the work of laboratories in their jurisdiction. The survey indicated that there was a marked variation from standard methods in many of the laboratories visited. When one considers the help that bacteriological examinations have given in the sanitary control of milk, and the errors of omission and commission in following standard methods, the possibility is evident of their being even more useful and better correlated in the sanitary control of milk when they are properly performed.
