(From the Pharmaceutical Record, December 15, 1884.) 
The following list, though not quite complete, will meet a 
long-felt want. How often, in reading chemical articles, are we 
met with the statement that this or that chemist’s test was em- 
ployed, the nature of which has escaped our memory, and ne- 
cessitates a, sometimes fruitless, search through many books of 
reference. Some of the tests are identical, and a few of them 
are, or seem to be, contradictory.
