Many of these new compounds are completely stable in hard water, and can be used in acid or alkaline solution, and their detergent power is equal to, and frequently greater than that of soap. As a rule they are more soluble than the soaps and this enables washing to be done in cold water, whereas most ordinary soaps are not very soluble in cold water. But because of the expense of treating the raw materials before manufacturing the detergents, they are as a rule more expensive than soaps, and except in special circumstances they cannot compete with it. At present their use is confined to the textile and laundry industries for special purposes, and in cosmetics. Almost all face creams, salves, shaving creams, etc. contain soaps and the newer detergents can usually replace soap with advantage.
So far the public is scarcely aware that a new type of detergent is beginning to challenge soap, but in time the new products will compete with soap on fair terms, and it will be interesting to see if scientific research is successful in ousting a product which has been used for 2,000 years.
Lesson Sermon First Church of Christ, Scientist.
Christian Science—is the subject of the Lesson Sermon read in all Churches of Christ Scientist, throughout the world on Sunday, June 25. Golden Text:—Isaiah 49:13.
"Sing, O heavens; and be joyful, O earth; and break forth into singing, O mountains: for the Lord hath comforted his people, and will have mercy upon his afflicted." Among the citations which comprise the Lesson Sermon is the following from The Bible:—"And he said unto them, Go ye into all the world, and preach the gospel to every creature. And these signs shall follow them that believe; In my nàme shall they cast out devils; they shall speak with new tongues; They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover. (Mark 16: 15, 17, 18).
The Lesson Sermon also includes the following passage from the Christian Science textbook, "Science and Health with Key to the Scriptures," by Mary Baker Eddy:—"Today the healing power of Truth is widely demonstrated as an immanent, eternal Science, instead of a phenomial exhibition. Its appearing is the coming anew of the gospel of "on earth peace, good-will toward men. Now, as then, signs and wonders are wrought in the metaphysical healing of physical disease; but these signs are only to demonstrate its divine origin,—to attest the reality of the higher mission of the Christ power to take away the sins of the world." insecticide for 50 yrs.
