||M.D. thesis. The results are reported of cutaneous tolerance tests on guinea pigs, in order to study, among irritants, those that are corrosive to skin on account of their acidity or basicity. The experiments with histological tests were made with sulfuric, hydrochloric, nitric and acetic acids and with sodium, potassium and ammonium hydroxides. The results do not confirm the hypothesis that acids of low pH are not harmful to the skin. For bases, below pH9, the harmlessness is confirmed. All cutaneous lesions due to industrial products whose pH is equal to or less than 4, or equal to or greater than 12 should be considered as compensatable as occupational injuries.
