John and presented before the Division of Agricultural and Food Chemistry of the A M E R I C A N C H E M I C A L S O C I E T Y at the spring 1 9 4 9 meeting of the A M E R I C A N C H E M I C A L S O C I E T Y in San Francisco and the
fall meeting in Atlantic C i t y . This first number is a perfect illustration of the desirability of establishing a special medium for the publication of certain symposia presented at A M E R I C A N C H E M I C A L S O C I E T Y meetings. Only a relatively small percentage of the papers can be said to be strictly chemical i n nature. M a n y deal with such subjects as the toxicological effects of economic poisons, public health aspects, etc. Only through the establishment of the A D V A N C E S I N C H E M I S T R Y S E R I E S was it possible
to present the symposia in their entirety.

In introducing this series we are highly optimistic in our belief that it will help to solve at least some of the present publication problems facing the A M E R I C A N C H E M I C A L S O C I E T Y .
