similar to that of toxins in infectious diseases.

COMMENTS - When Dr. Alexander Villers was an infant, he had diphtheria. Known remedies had failed to 
arrest the disease. His father, Dr. Dominic von Villers, was in despair. 
Taking counsel with his friend, Dr. Beck (of Monthly in Switzerland), the latter was struck with the likeness of 
the case to the effects of Merc-cy. in some poisoning cases, reports of which he had just been reading and he 
suggested the remedy. 
A small quantity of the salt was procured and a potency was rapidly made and ad ministered. 
Improvement soon set in and recovered followed. Alexander Villers, saved by Merc -cy., lived to do brilliant 
work with the same remedy when practicing in St. Petersburg. 
Merc-cy. has taken a sure place at the head of remedies for diphtheria, and as an efficient prophylactic in 
diphtheria cases. Villers had better results with the 30c than with any lower potency.  
In the sensational New York poisoning case of February, 1899, Mr. Henry C. Bar nett, the victim, was treated 
for diphtheria by his doctors before the cause of the illness was discovered.  
Nash reported as particularly indicating it a chronic sore throat of public speakers with ra wness in spots and 
abroken-down appearance, as if about to ulcerate and the feeling that “it hurts the patient to speak.”  
Diphtheria membrane in throat, mouth and at anus. Swallowing is impossible or causes severe cutting pains. 
Thought of food causes retching. 
Beck noted the extreme feebleness, trembling, syncope. Profound prostration. Icy coldness, general coldness 
with nausea. Dark and persistent hemorrhage. Varicose veins with great tenderness on left leg. Cyanosis.
