High; the distortion has evidently taken place through the use of unseasoned timber and consequent warping of the woodwork.
But it seems pretty clear that if there is any change in weight consequent on chemical change, it is too minute to be of im- portance to the chemist, though the methods of modern physics may settle the question.
To represent two million cases of sickness and a consequent loss of several million francs.
But on account of experimental errors in weighing and measuring, and through loss of material in the transfer of substances from one vessel to another, such analyses are rarely trustworthy to more than one part in about Soo; so that small changes in weight consequent on the chemical change could not with certainty be proved or disproved.
Landolt and others, made it at first appear that the change in weight, if there is any, consequent on a chemical change can rarely exceed one-millionth of the weight of the reacting substances, and that it must often be much less.
