To quickly assess the difficulty of the text, read a short excerpt:
Care must be taken that the whole of the platinum wire is covered with mercury while .the bullet remains in the gas, otherwise there is a risk of air entering the tube between the mercury and the wire (fig. 79). After standing for an hour, the bullet is withdrawn from the absorption tube. This must be done with some precaution, so as to prevent any gas being removed from the tube. It is best done by drawing down the bullet by a brisk movement of the wire, the gas being detached from the bullet ...during the rapid descent of the latter into the mercury. The bullet may then be more slowly removed from the tube. As sodic phosphate and sodic sulphate contain water of crystallization, and a corresponding proportion of this is liberated for every equivalent of sodic chloride formed, care must be taken that the bullets are not too small, else the water set free will soil the sides of the eudiometer, especially if there is a large volume of gas to be absorbed. As a further precaution, drive off some of the water of crystallization before casting the bullet.
