The experiment reported here, gave the following answers to the questions asked (see introduction): a. Water with 30 ppm F gave deleterious effects on wethers. A considerable difference was observed as compared to animals given about 1 ppm F in their water, see Table IV. b. The toxicity was slightly less from bore hole water containing 30 ppm F, as compared to Nairobi tap water with added fluorine to 30 ppm F. The difference in toxicity may be due to the very high content of minerals in the bore hole water, see Table I. c. More fluorine was excreted in faeces when aluminum chloride was added to the diet, as compared to animals which did not receive aluminum chloride. Aluminum chloride had no alleviating effect on fluorosis, but apparently decreased gut absorption of fluorine and also reduced fluorine retention in the bones, se Table VII. Under the conditions of this experiment, toxic levels of fluorine were considerable lower than the quoted safe levels in the literature.
此处报告的实验，对所提问题（见引言）给出了以下答案：a. 含30 ppm氟的水对阉羊产生有害影响。与饮用含约1 ppm氟的水的动物相比，观察到有相当大的差异，见表IV。b. 与添加氟至30 ppm的内罗毕自来水相比，含30 ppm氟的井水毒性略低。毒性差异可能是由于井水矿物质含量非常高，见表I。c. 与未摄入氯化铝的动物相比，在饮食中添加氯化铝时，粪便中排出的氟更多。氯化铝对氟中毒没有缓解作用，但显然降低了肠道对氟的吸收，也减少了骨骼中的氟潴留，见表VII。在本实验条件下，氟的毒性水平远低于文献中引用的安全水平。
