Below the surface, water samples must be collectedby means of some apparatus which can be closed atthe required depth. There are many forms which aresuitable, and as they are generally made to carry athermometer the latter may be discussed here. There is one rule which is of the greatest importance—that is, that no thermometer is to be used unlessits errors are known. All the forms of thermometerused for marine investigation can be bought with acertificate of examination at some recognized in-stitution. In England the examination is made atKew, in Germany
