APPENDIX TO THE INTKODUCTION TO THE ZOOLOGICAL REPORTS. 



TABLE showing the Positions of the Soundings obtained in H.M.S. Challenger; the 

 Temperature and Specific Gravity of the Surface and Bottom Water ; and the 

 Stations where Serial Temperatures, Trawlings, or Dredgings were procured. 



(la the present volume, and in tlie second volume of the Zoological Series, there are some small discrepancies 

 between the bottom temperatures entered in the body of the Eeports and those in the Tables. This Ls owing to 

 our having adopted at first a system of correction whose accuracy we were afterwards led to doubt. In the 

 Tables the temperatures are recorded as they were taken, without correction. — C. Wt. T.)
