are found under colder layers, contrary to the current theory, or, in other 

 words, the seasons are later in proportion to tlic greater depth of water. 



Thus, in winter, there is a continual increase of temperature downwards, 

 or warmer layers under cold layers; in spring (March), above warmer, under-
