instead of spirit of chloroform. No. 4 (from Cupar Fife) 
added the spirit in such proportion that it possessed the smell 
of whisky; whilst No. 18 (from Airdrie) dispensed the chloro- 
form without any spirit, so that it remained insoluble at the 
bottom of the bottle. This error might have proved serious 
if the last dose in the bottle, containing all the chloroform, 
had been swallowed by the patient. The seven mixtures 
to which the following numbers relate contained disagree- 
able looking sediments — 17, 24, 45, 46, 56, 74, and 78. 
One more potassium iodide prescription was made to 
contain the same quantity of salt as the others, but the 
solution made up to two instead of six ounces. The fol- 
lowing shows the result : —

With the view to test further the range of inaccuracies 
in other and more valuable medicines, Dr. Sinclair and I 
arranged to have a few different prescriptions dispensed, 
and he accordingly wrote out five, having the following 
composition : — 
R. Argent. Nitrat 3 j 
Aq. Distillat § j 
M. Fiat lotio. To be kept from the light. 
These were subject to analysis, and the following Table 
shows the results : —
