The general statement referred to was made in a speech some years since by Sir Spencer Wells.

For recent scattered cases of feeble opposition to vaccination by Protestant ministers, see William White, The Great Delusion, London, 1885, passim.
For opposition of the Roman Catholic clergy and peasantry in Canada to vaccination during the smallpox plague of 1885, see the English, Canadian, and American newspapers, but especially the very temperate and accurate correspondence in the New York Evening Post during September and October of that year.
Another class of cases in which the theologic spirit has allied itself with the retrograde party in medical science is found in the history of certain remedial agents; and first may be named cocaine.

As early as the middle of the sixteenth century the value of coca had been discovered in South America; the natives of Peru prized it highly, and two eminent Jesuits, Joseph Acosta and Antonio Julian, were converted to this view.
But the conservative spirit in the Church was too strong; in 1567 the Second Council of Lima, consisting of bishops from all parts of South America, condemned it, and two years later came a royal decree declaring that "the notions entertained by the natives regarding it are an illusion of the devil." As a pendant to this singular mistake on the part of the older Church came another committed by many Protestants.

In the early years of the seventeenth century the Jesuit missionaries in South America learned from the natives the value of the so-called Peruvian bark in the treatment of ague; and in 1638, the Countess of Cinchon, Regent of Peru, having derived great benefit from the new remedy, it was introduced into Europe.

Although its alkaloid, quinine, is perhaps the nearest approach to a medical specific, and has diminished the death rate in certain regions to an amazing extent, its introduction was bitterly opposed by many conservative members of the medical profession, and in this opposition large numbers of ultra-Protestants joined, out of hostility to the Roman Church.
