he title quotes a famous remark by Charles N. Reilley on the occasion of his Fisher Award address at the April 1965 ACS national meeting. I have just re-read a copy of Reilley's opening remarks, in which are found some timeless gems on the teaching of analytical chemistry.

have been an important part of the intellectual vitality that analytical chemistry enjoys as a discipline today. For the future, though, changes toward modernization must continue. Education in science must be a continuing frontier, else it will stagnate and fail. In that context, I wonder how vigorously the existing mix of topics in the beginning underToday, the overwhelming growth of know'graduate analytical course can be justified as edge, there is simply no time for easily outdated frills matching up with what students need to know in our curriculum. As a result, it is essential that about analytical chemistry when they become stress be given to core concepts-those principles professional chemists. I throw a specific stone.
