The company provided wet drilling equipment, but that, as the record Indisputably shows, was, in and of itself wholly insufficient to protect the workers froa silicosis. As to the law in effect when the disease was contracted, whether the contraction of silicosis shall, or shall sot, be deemed to be accidental depends "on tho particular circumstances of tho cose and. aeoldontal features, or the absence thereof." There was accidental injury hero. Silicosis is in large part preventable by one device cr another. Claimant is clearly and unquestion ably entitled to roeover compensation.

The pharmacologic action of sodium thiosulfate in the treatment of arsenic poi soning is still e controversial issue.
