2 As in many cases the figures given on the plates accompanying this Catalog are 

 necessarily reduced, we have given the principal dimensions, diameter over all 

 across the face, and greatest thickness including the crystals or covers as they now 

 are. It is proper to observe that crystals when broken may be replaced by others 

 of a different curvature, and that this measurement, for purposes of comparison, 

 may therefore at times prove to be misleading.
