suggestion of Dr. Sinclair, I have annexed the prices 
charged by each, for the two bottles, as in his opinion it 
might prove of general interest to dispensers, and will 
make the table more perfect, because from those who charge 
most, the greatest degree of accuracy should be expected. 
I may further state, that from eacli important town, I 
endeavoured as far as possible to have one lot dispensed by 
a druggist having the highest reputation and another by 
one of the lowest class, but I found it difficult to carry out 
this exactly, so that the prescriptions have been made up 
more generally by high class or respectable druggists than 
by those of a lower class. 1 have, however, as far as pos- 
sible, marked those who could be recognised as having 
decidedly large and respectable shops, and those that were 
decidedly low class; the others may all be accepted, I 
believe, as respectable, and many may even be termed high 
class druggists.
