or walk steadily, and, finally retching and vomiting, and death by

Devergie states that acute poisoning with nitrate of silver,
administered in the shape of pills, is more frequent than one would
suppose. Yet Dr. Powell[1] states that it should always be given in
pills, as the system bears a dose three times as large as when given in
solution. The usual dose is from one-quarter of a grain to one grain
three times a day when administered as a medicine. In cases of epilepsy
Dr. Powell recommends one grain at first, to be gradually increased
to six. Clocquet[2] has given as much as fifteen grains in a day, and
Ricord has given sixteen grains of argentum chloratum ammoniacale.
