The veterinary homœopathist does very well in selecting his remedy by the human pathogenesis. Why should not the same mode be applicable to vegetables? We have invited our fellow-beings to try it; we have not only invited them to teach, and to cure, and to make themselves sick, in order to discover the true means of healing; but we have encouraged them to suffer themselves to be persecuted, and even imprisoned, as a reward for their labors of love, we have said to them; whilst the world is hesitating whether it should accept or reject the blessing offered by Hahnemann, let us lose no time; there are other regions where the evil is still triumphant, and where truth is not even known by name; let us expel error from its last hiding-places. And we have never failed in meeting corresponding souls that would hear us and follow us. And thus it is that homœopathy, this physical reflex of the Christian redemption, combats evil by itself, pursuing it from region to region until it shall have been exterminated from the world.

Now let us describe the practical part of our proving.

From the first, frontal headaches, with pressure above the orbits, have been observed with much regularity not only by the three provers whose symptoms are published, but also by other provers who continued the proving only for a few days.

Until the 20th day, these headaches were often accompanied by fever, with chill, heat, sweat, shudderings followed by sore throat, cough and greenish mucous expectoration.

The palpitation of the heart which occurs during the whole period of the proving, and with particular violence at the end of the third proving, appears to be represented in the case of the second prover by violent muscular pulsations occurring in the same chronological order. The hard, large-sized, fragmentary stools, and their painful expulsion which sometimes caused a falling of the rectum; the frequent emission of flatulence preceded or accompanied by colic, with sensitiveness of the abdominal integuments in the case of the first prover, are very constant symptoms of this drug; they were observed from the first and increased until the last days of the proving.

We will likewise point to the general or partial weakness, which, in the case of the third prover, were followed by violent pains in the loins.

The white coating of the tongue which was observed on the first day, gradually limited itself to a yellow line along the middle. Among the less general symptoms which were observed during the whole time of the proving, we may note the want of appetite, the bitter taste of food, the cutaneous eruptions, the swelling of the mucous membrane of the palate, the thick urine, and lastly the pain in the groin or the right ileo-femoral articulation.

In the emotive sphere the drug induced a great irritability. The dreams about a change of form occurred very generally to the three provers. The second prover had the same dreams on two successive nights.

After a careful comparison of the symptoms of the Solanum tuberosum ægrotans with those of the other known remedies of our Materia Medica, we have found them to agree with the symptoms of the following drugs which we enumerate in the order of their importance:
