Large crystals!

Dear Editor:

I was excited to see the article on the Singapore Crystal Growth Challenge in IUCr Newsletter Volume 10(3). As we grow crystals of chrome alum in one of our freshman laboratories here at Illinois State, it was nice to show the students just how large some of these crystals can grow! However, my students and I have to wonder about the caption for the 'prize-winning crystal' displayed. Certainly we can not be the only ones in the crystallographic community who would notice that those units must be cm3 not mm3! A quick check of the referenced SNIC website reveals the truth. I guess no one ran checkCIF on that one!
