Excerpt from Report on the Scientific Results of the "Michael Sars" North Atlantic Deep-Sea Expedition 1910, Vol. 1 Owing to various circumstances not altogether within my own control, the completion of this paper has been delayed to an extent which I greatly regret, particularly as this has inconvenienced the authors of other parts of the scientific report on the Michael Sars Expedition. Shortly after the termination of the cruise preliminary reports were published on its results, including the researches in physical oceano graphy. Subsequently communications on certain special geophysical problems were issued from time to time, either in publications or in the form of lectures. A good deal that is contained in this paper may therefore be already known to the reader. III the interval that has elaps ed, however, new investigations have furnished us with observations which supplement the Michael Sars material, and other progress has been made which has been of value for the final working-up of the results. I have endeavoured to present the subject in a form adapted for biologists as well as geophysicists. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
