Life insurance is one of the best forms of fnfvesimenl, because if gives, afler one deposit, an inslanf guarantee fo repay principal and interest and more. -IOHN WANAMAKER N March 8, 1899, THE PENN MUTUAL LIFE INSURANCE COMPANY made a radical departure. It decided upon the issue of any one of its contracts of insurance it would immediately endorse thereon the following: M ' This policy is absolutely incontestahle from date of issue for any cause, except non-payment of premium, anything in this contract to the contrary notwithstanding. THE contract of life insurance is so broadened and liberalized that it is a simple and I ' inviolable promise to pay at a given date, or upon death. It is the crystallization of O the idea expressed in the few words: You pay usg we pay you. THE above endorsementmakes a world-wide contract, free from all conditions as to residence, occupation, travel, habits of life, and as to manner, time, or place of death. It is the ultimate in life insurance, for no contract can possibly go any farther than to be an unconditional promise to pay. WITHOUT any increase in premium, or without any stipulation as to the use of divi- dends, the policies embrace: FIRST-Automatic extension-the longest. SECOND--Paid-up insurance-the largest. THIRD-Cash or Loan Values-the most liberal. FOURTH-No conditions as to resi- dence, occupation, suiclde, dueling, violation of law, or military or naval service. Not approached by the IT will command world-wide attention and instant approval. It shows that the PENN COllI1l'ZlCt of Zlliy OTITCI' COITTDZIITY MUTUAL has reached the goal toward which others are sauntering.

,Q Anesthesia by Nitrous Oxid and Uxygen in Combination Of late years the admixture of pure oxygen with nitrous oxid for anesthetic use has attracted considerable attention and been the subject of much experimentation. 'l'he claim made for this admixture is that it eliminates the asphyxiating feature from nitrous oxid anesthesia, and that it therefore permits of thc production of the anesthetic state in which, for one reason or another, nitrous oxid alone is contraindicated. 'l'he apparatus for administering NitrousOxid and Pure Oxygen in combination, as shown on the opposite page, frilly meets the requirements for this purpose, and it will be found as perfect for giving either gas separately. A brief description will best demonstrate this. Cylinder A contains Pure Oxygen. Cylinder ll is filled with Nitrous Oxid. C and IJ are rubber bags, of different colors, to avoid confusion. E and Fare keys which open the valves of the cylinders and allow the gas to ull the bags through the tribes G and H. 'l'he valves O and I' being closed, the gas remains in the bags. ily opening O Nitrous Oxid is admitted to Mixing Chamber M, from which it flows through the covered rubber tube to the lnhaler. When it is desired to combine Pure Oxygen with the Nitrous Oxid, open valve l', which admits the Oxygen to the Mixing Chamber, and both flow together to the lnhaler. 'l'he proportion of Oxygen used will be determined bythe degree to which valve 1' is opened, and the gauge on the valve will assist the operator in lixing the quantity. lint it must be remembered that exact percentages are not practical and not desirable, because of the varying susceptibility of patients. N is a convenient handle by which the apparatus, which balances nicely, may be carried. For compactness in transportation the rod which supports the inhaler may be run down to the level of the Mixing Chamber. The Cylinder for Oxygen is always red. The Cylinder for Nitrous Oxid is black, and there need be no mistake in placing them in the apparatus. The S. S. White Dental Mfg.
