We have started at the OHP observatory an observing program for classifying stars in Golay’s boxes of photometrically identical stars. So far 380 stars have been observed at 80 Å/mm dispersion, covering the range from BO to G8. The main result is that stars belonging to the same box are spectroscopically identical at this dispersion if one considers classifications taken from different well experienced observers. This remains true within the current errors of spectral classification. The problem presented by the Ap and Am stars is discussed in detail.
