It is a most fortunate circumstance, that the Cow Pox, when communicated to the human species, is so mild a disease as scarcely to merit the appellation of a malady.

The security which the Cow Pox affords against the Small Pox is not of a temporary nature, but is as durable as that which is produced by the Small Pox itself.

I have been so fortunate as to discover a method of rendering the human body secure from the infection of the Small Pox.

The introduction of the Cow Pox into the human constitution is attended with no risk, and is productive of no inconvenience.

The practice of inoculation for the Small Pox, though it has been productive of much good, has also been productive of much evil.

The Cow Pox is a disease of so mild a nature, that it may be communicated to the most delicate constitution without the least apprehension of danger.

The discovery of the Cow Pox as a preventive of the Small Pox is one of the most important that has ever been made in the annals of medicine.

I am well aware that the introduction of a new practice, however salutary, will always meet with opposition.

The prejudice against the Cow Pox is so strong in some minds, that it will be difficult to remove it.

It is a matter of astonishment to me, that a disease so mild as the Cow Pox should be capable of producing so powerful an effect.

The Cow Pox is a disease sui generis, and is not to be confounded with any other.

The practice of vaccination, if generally adopted, would put an end to the ravages of the Small Pox.

I have no doubt that the time will come, when the Small Pox will be known only by name.

The Cow Pox is a blessing to mankind, and ought to be universally adopted.

The opposition to vaccination arises from ignorance and prejudice.

The benefits of vaccination are so great, that they cannot be too highly estimated.

I have encountered much opposition, but I have also met with much encouragement.

My sole object has been to benefit mankind, and I trust that my labours will not be in vain.

The most formidable enemy of truth is not falsehood, but prejudice.

It is a great satisfaction to me to reflect, that I have been instrumental in saving so many lives.
