appendix, for a striking instance of the misapplication of a symbolical formula. 
A process is given for making nitrite of soda to be used in the preparation of 
spirit of nitrous ether, and the resulting salt is represented by the formula 
NaO,N0 3 . The objection is that the nitrite of soda will form only a small por¬ 
tion of the product formed by the process, and that therefore the formula is wholly 
inapplicable.

Pharmacopoeia.* —The following list, if not quite complete, comprises at least the
