I am fully aware of the difficulties with which we are presented, in the form of shortage of help, facilities, funds and authority, but these are the reasons why the practice of Occupational Medicine is so poor in performance that cases of lead poisoning abound in industry, despite our definitive knowledge as to how to prevent all of such cases

I have my fingers crossed also about the pathology of poisoning by these compounds.

The point I was making, from the figures which I collected in tabular form was that irrespective of the variation in absolute no anal values, the same method in the hands of the same workers showed a considerable difference in the lead content of the blood of the average-individual as compared to those with industrial exposure or with signs of lead poisoning.

The latter is used for washing purposerff, .so it must not be poisonous. 2.

I should say, also that in- ray view, the combined mechanisms of an incomplete recovery from lead poisoning, and the additional toxic effect of other disease prodess, including infections are very likely to be much more subtle than that represented by gross changes,in the distribution of lead in the body.

I would not advise this, for it might be disastrous, and would certainly upset the workmen, economically and psychologically, to a much greater extent than they will be because of the occurrence of some cases of lead poisoning among them.

It will serve no useful purpose, on such an occasion, and will further confuse the situation, if X find it necessary to deal in an apparently critical vein with certain of the discussions* X hope to be able to present a brief summary which will crystallise the discussion to the practical advantage of men who will be Interested primarily in the diagnosis of lead poisoning and in the means of recognising and preventing hasordous lead exposure.

As we pointed out in that report some further protective means are necessary to prevent the de velopment of ease of lead poisoning.

In some recent cases of tetraethyl lead poisoning in tank cleaners that we have had here, men with high urinary lead output who are hospitalised also show a high faecal output out of all pro portion to what could have been taken in the diet, and after a period of time which would discount old faecal remnants.
