5B6 Dr. Hamilton’s Account , &c. 
convinced, from thefe trials, that the principal or fpecific 
efficacy is in the calomel, as large dofes of opium alone, 
or joined with camphire, have proved unfuccefsful. I 
am fo well fatisfied of the advantages of this practice, 
that, if called early in the diforder, I dire6t ten grains of 
calomel with two grains of folid opium, made into a bolus 
with any conferve, to be taken immediately, and re- 
peated in fix hours. I have feldom occalion to order a 
third dofe, the patient being generally relieved by the 
fecond, if the firft has failed. I did not adminifter it in 
the cafe here related, becaufe the alarming fituation the 
patient was in when I came to him required the bladder 
to be emptied without delay*
