A412 Dr. Fothergill on the practice of sleeping on the wet ground. 
pleasurable kind. A species of deception, which may often impose 
on parents and guardians, but cannot eed elude the penetration of a 
sagacious physician. 
Perhaps it will be objected, if ‘sleeping on the ground, or exposure 
to the night air at a late hour be so very injurious, whence is it, that 
any of those, who indulge these habits, escape with impunity? The 
same question may be urged, when a malignant fever rages with epi- 
demic violence, whence is it, that some persons in the infected 
neighbourhood escape, and continue to enjoy their usual health? 
A few such escapes thus betray many into a fatal security. But is it 
not more prudent to take warning from the calamities of others, than 
to run headlong into dangers, that might easily be avoided ?
