Abstract
The administration of Vitamin B12 to the incubating fertile eggs caused no marked toxic effect, but an evident diuretic action.
The effect on the toxicity of Nicotine by the changes produced in the morality rate, growth of embryos and the metabolism of water, electrolytes and vitamin B1 was examined by the combined administration of Nicotine and vitamin B12. Development of Nicotine hydrops was not inhibited in this experiment indicating that vitamin B12 has little counter action against the toxic effect of Nicotine.
