But granting that many could be shown to be of doubtful validity, this would not lessen the adverse publicity, and'it is my considered opinion that we must find means of securing more accurate diag nosis of lead poisoning or face the likelihood of widespread governmental prohibition of the use of lead paints on dwellings.

The figures on childhood lead poisoning are pretty much a hodge-podge and I would ask that the whole be considered rather confidential.

Fawcett: I regret very much to have to say that we have no information of any kind on the toxicity of lead tetraphenyl.

Although this hook is not concerned with the toxicology of lead or industrial health exposures, it contains much valuable information on the production and uses of lead and its compounds.

Workmen's compensabon is the second largest property-liability insurance line, it is topped only by automobile insurance Work men's compensabon premiums are about II percent of the total premium income Among the ten leading pnvate insurance groups, four denve at least one-third of their business from workmen's compensabon Classifications ot Insurers Private insurers can be classified according to their legal form of orgamzabon, their mar keting methods, and their pncing policies Legally, insurers may be classified as propnetary or cooperabve insurers Propnetary insurers have owners who bear the risks of the insurer and whose representabves manage the operabons The leading example by far is the stock insurer owned by stockholders who elect the board of directors In 1970 of the 383 pnvate groups in workmen's compen sabon insurance, about 68 percent were stock companies, with about 70 percent of the total premium volume Cooperabve insurers have no owners other than their policyholders The leading exam ple is the advance premium mutual whose board of directors is elected by those policyholders who exercise their nght to vote Unlike stock insurers, these insurers have no capital stock Instead retamed earnings serve as a cushion against adverse expenence In 1970, mutual insurers, about 32 percent of the pnvate workmen's compensabon insurers, wrote 30 percent of the premiums earned Almost all of the 1970 workmen's compen sation insurance premiums not wntten by stock or mutual insurers were wntten by re ciprocal exchanges which, m their modem form, closely resemble advance premium mu tuals The relabve importance of stocks, mutuals, and reciprocal exchanges vanes among states In several states, stock insurers write over 75 percent of the business In a few states, mu tual insurers dominate the private insurance field Since 1951, when their share was 59 per- 192
