1941 to 1952 inclusive (12 yean), 689 cases were re ported to our state agencies. A breakdown as to the type of caw involved in this group should be of some interest. Ten cases were awarded total permanent disability, 384 cases were given permanent partial awards, and 295 cases were given temporary disabil ity by the compensation bureau. The largest num ber of cases reported during any one year was 94 in 1942, and the smallest group was 22 in 1950.
It is interesting to note that there has been a de cided downward trend during the past six years, as evidenced by the following statistics: in the period from 1941 to 1946, 453 cases were reported, while from 1947 to 1952 there were 236.
Although the yearly average for the past six years has been about 40 cases, it is significant that only 22 cases were reported in 1950, 31 cases in 1951, and 30 cases in 1952. These facts by themselves tell the story of the great progress being made in this state.
Our survey throughout the country (Table III) was made by personal communications with the various state agencies, such as the health departments in some states, and compensation commissions and bureaus in others. The period covered by our questionnaire was from 1946 through 1952 (five years). Thirty-eight states reported their findings. Seven states (Delaware, Louisiana, North Dakota, Oklahoma, Oregon, Ver mont and West Virginia) informed us that this dis ease was not reportable in their states (Louisiana did, however, report one fatal case). Three states (Iowa, Rhode Island and Texas) had no available statistics.

although the condition is reportable by law. One state (South Carolina) completely ignored our ques tionnaire.
The ten states reporting the largest number of cases were as follows: Pennsylvania, 419 (five years); Ohio, 332 (five years); California, 208 (four years); New Jersey, 177 (five years); New York, 166 (four years); Minnesota, 162 (five years); Illinois, 137 (five years); Massachusetts, 131 (four years); Virginia, 87 (five years) and North Carolina, 72 (five years). Thus we see that in these ten states, 1891 cases (80 per cent) out of a total of 2337 throughout the country, were reported.
Our survey also shows that there has been a de cided drop in the over-all mortality rate from this disease. Only 20 deaths have been reported through out the country during the past five years. Of the deaths reported, nine occurred in New York and the remaining 11 cases were distributed in six different states. This is in sharp contrast to past records as given by Hoffman,* which show that in 1936, 132 deaths occurred; 71 in 1942, and 47 in 1943.
CONCLUSIONS
It is generally agreed that it is quite impossible to obtain absolute and reliable information regarding the incidence of industrial lead poisoning in many states. This unhappy situation is the result of sev eral factors such as: (1) failure on the part of some companies to report their cases, (2) non-mandatory laws for the reporting of these cases in some states, (3) where reportable, cases not always checked for reliability, (4) lack of sufficient personnel in the agen cies of some states, (5) listing and classification of cases improperly catalogued and (6) listing of only cases of death in some states. Fortunately for us, our New Jersey agencies are devoid of these deficiencies and are doing an outstanding job.
We are convinced that the term "Plumbo-phobia" is applicable to this aspect of the subject in that there are considerably fewer cases of lead poisoning today than one would be apt to believe from reading some books and periodicals which are dearly outdated. We feel that there is some justification for stating that there has been and is continuing to be a definite and decided downward trend in the frequency of indus trial lead poisoning throughout the nation.
Our investigation dearly discloses that lead poison ing is becoming less and less frequent, and that lead poisoning in the fatal form will be a rare occurrence even though lead and its compounds are being used in greater quantities today than ever before. Credit for this great progress can be given to (1) the lead industries: they are cognizant of their responsibility and have continued to provide the necessary capital to install the most modern protective equipment, as well as providing the services of competent medical offidals; (2) to the state health and compensation de partments, which provide essential aid and assistance wherever and whenever requested; (3) to such organi zations as the Lead Industries Association and the American Industrial Hygiene Association, of which your local organization is an integral part.
We sincerely hope that our survey will serve a useful purpose in providing us all for the first time with substantial, comprehensive statistical data which hitherto have not been available from any one source.
