loped on all sides. I scarcely remember any other organic compound that crystallizes 
so readily. The crystals, as appears from the measurements of Quotixo Sella, are 
isomorphous with those of the corresponding phenyl-compound*. Sella has communi- 
cated to me the following details respecting his examination.
