Nujol not only meets-but exceeds the standards for liquid petrolatum set by the Pharmacopoeias of the United States and other nations.

The expert chemists of the Nujol Labora-
tories of the Standard Oil Co. (New Jersey)
have been able to produce absolutely pure
liquid petrolatum of every viscosity from
a water-like fluid to a jelly.

The viscosity of Nujol was determined
after exhaustive research and clinical test,
and is in strict accord with the opinions
of leading medical authorities.

Le ding Venereal Experts in London, Edinburgh, Brusse's,etc., unanimously agree that our detoxicated gonococcal vaccine is great'y superior to any other hitherto produced, and that this discovery marks an important advance in vaccine therapy. (See Prictitioner, Jan., 1920, etc.) Since the discovery of the detoxication of the Gonococcus, the process bas been applied with equal success to most of the other pathogenic organisms. Detoxicated Vaccines (Polyvalent) are now prepared by us for:

1-Influenza and Pneumonia.
