The continued application of leaded gasoline on such surfaces (for as long as a decent regard for the comfort of the animals would permit) exerted no influence on the absorption of the lead compound.

Moreover, lead has been employed in the treatment of cancer (Blair Bell et al), unsuccessfully I believe, despite a^few V. o i c c- suggestively beneficial effects,/partly because lead compounds are believed to be especially injurious to embryonic tissues, andk P<'V partly because of statistics (not very convincing), that indicate that workmen in lead trades have an unusually low incidence of cancer.
