cause thee to be smitten before thine enemies: thou shalt go out one way against them, and flee seven ways before them, and shall be removed into all the kingdoms of the earth.”—Deut. xxviii.

"If thou turn away thy foot from the Sabbath, from doing thy pleasure on my holy day; and call the Sabbath a delight, the holy of the Lord, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasures; nor speaking thine own words: then shalt thou delight thyself in the Lord; and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father; for the mouth of the Lord hath spoken it."-Is. lviii.

Although these promises for obedience and threatenings for disobedience were directly made to the Jews, they did not concern that nation alone, but the whole human race. At the time Jehovah revealed Himself to the Jews, the Earth was full of ignorance, idolatry, and gross wickedness; and the laws and ordinances then enjoined were necessary that He might be acknowledged as the only true God, the Creator, Upholder, and Governor of all things, and therefore the right object of worship. This Divine revelation to one people, and through them, a means of instruction and warning to mankind generally, was an act of infinite wisdom and mercy.

The following quotations intimate that it was God's design to speak to all the world through his special government over the Jews: "Also the sons of the stranger, that join themselves to the Lord, to serve him, and to love the name of the Lord, to be his servants, every one that keepeth the Sabbath from polluting it, and taketh hold of my covenant; even them will I bring to my holy mountain, and make them joyful in my house of prayer for mine house shall be called an house of prayer for all people.-Is. 56. For the nation and kingdom that will not serve thee shall perish: yea, those nations shall be utterly wasted.-Is. 69. All the ends of the world shall remember and turn unto the Lord: and all the kindreds of the nations shall worship before thee. For the kingdom is the Lord's: and he is the governor among the nations.-Ps. 22. Who shall not fear thee, O Lord, and glorify thy name? for thou only art holy for all nations shall come and worship before thee; for thy judgments are made manifest."-Rev. 15.

Nor may we regard the Sabbath as part of the Jewish Ceremonial Law. In Paradise God blessed and sanctified the Seventh day, and made it a day of sacred rest, for the commemoration of creation, for the worship and honour of Himself the great Creator, and for the advancement of

man's spiritual essence. And it was observed by the Jews before the giving of the moral law on Mount Sinai, or of those minute observances of the ceremonial law subsequently enjoined, as Exodus xvi. abundantly proves. And when God promulgated the moral law, He commenced the commandment on the observance of the Sabbath, REMEMBER the Sabbath day to keep it holy : implying its previous existence. The ceremonial law being only "a shadow of good things to come," necessarily ceased when the Messiah, to whom it pointed, had finished his mission.

In conclusion, a weekly Sabbath never has been, and we believe, never will be, abrogated. It is embodied in the moral law which the Redeemer has established in its fullest honour and authority, as the true standard of holiness and rule of duty, for all classes of society to the end of time. And it is a special day for the cultivation of the holy principles of that law in which it is embodied, principles essential to the spiritual and organic life of time, and to the spiritual bliss of eternity. It is now held, as by the early Christians, on the first instead of the seventh day of the week, in memorial of the resurrection of Jesus Christ and of the Gospel dispensation. This was of Divine sanction, and very probably of Divine origin.

THE ATMOSPHERE.

PURE atmospheric air is part of man's nourishment. It is requisite for the constant oxygenation and decarbonization of the blood, to render it fit for vital purposes. Without it, food when digested by the stomach, and carried into the circulation, is not suited to the renovation of the frame. And it is a main agent in the removal of disintegrated tissue.

Pure atmospheric air is a mixture of 21 parts of oxygen, 79 of nitrogen, a variable quantity of aqueous vapour and ozone, and a fraction of carbonic acid (amounting on an average to 4 volumes in 10,000).

Ozone is a particular and very active form of oxygen. "It is a rapid and powerful oxydizing and corroding agent, much more so than ordinary oxygen; and possesses considerable bleaching properties." It is a natural antidote to malaria, so that the one helps to prevent the excessive accumulation of the other; and where it is pre

sent, malaria is not. "A temperature not much higher than that of boiling water destroys all its active character." A small quantity mixed with the atmosphere has a salutary influence upon animal life; except in particular cases, as a dry and irritable state of the bronchial tubes, and high febrile action. An excess of it commonly causes irritation and inflammation of the air passages; cough; quickness and oppression of breathing. When inhaled in large quantities, it is said to destroy life quickly.

The atmosphere very commonly contains other ingredients detached from surrounding objects. Some of these, as subtle organic matters and gases emanating from animal and vegetable substances in the process of decomposition, or from animal excretions, are very injurious, and sometimes most deadly. They induce-according to their peculiar kind and concentration, the duration of exposure to their influence, the constitution of the individual, the temperature, and the humidity and electrical condition of the atmosphereobstinate and complicated catarrhs, congestion, and inflammation; intermittent, remittent, nervous, bilious, and malignant fevers; cutaneous affections; diarrhoea, dysentery, cholera, scrofula; organic disease, consumption, and dropsy.
