SCIENCE. 



[N. S. Vol. XIV. No. 342. 



you that the greatest importance is attached 

 to the series of magnetic observations to be 

 taken under your superintendence, and we 

 desire that you will spare no pains to ensure 

 their accuracy and continuity. The base 

 station for your magnetic work will be at 

 Melbourne, or at Christchurch, in New 

 Zealand. A secondary base station is to be 

 established by you, if possible, in Victoria 

 Land. You should endeavor to carry the 

 magnetic survey from the Cape to your 

 primary base station, south of the 4:0th 

 parallel, and from the same station across 

 the Pacific to the meridian of Greenwich. 

 It is also desired that you should observe 

 along the tracks of E.oss, in order to ascer- 

 tain the magnetic changes that have taken 

 place in the interval between the two 

 voyages. 



8. Geographical discovery and scientific 

 exploration by sea and land should be con- 

 ducted in two quadrants of the four into 

 which the Antarctic regions are divided for 

 convenience of reference — namely, the Vic- 

 toria and Eoss Quadrants. It is desired 

 that the extent of land should be ascertained 

 by following the coast lines, that the depth 

 and nature of the ice cap should be investi- 

 gated, as well as the nature of the volcanic 

 region, of the mountain ranges, and espe- 

 cially of any fossiliferous rocks. 



9. A German expedition will start at the 

 same time as the Discovery^ and it is hoped 

 that there will be cordial cooperation be- 

 tween the two expeditions as regards mag- 

 netic and meteorological observations, and 

 in all other matters if opportunities ofier 

 for such cooperation. It is understood that 

 the German expedition will establish an 

 observatory on Kerguelen Island, and will 

 then proceed to explore the Enderby Quad- 

 rant, probably shaping a course south be- 

 tween the 70° E. and 80° E. meridians, 

 with the object of wintering on the western 

 side of Victoria Land, whence exploring 

 sledge parties will be sent inland. The 



Government of the Argentine Kepublic has 

 undertaken to establish a magnetic observa- 

 tory on Staten Island. 



10. You will see that the meteorological 

 observations are regularly taken every two 

 hours, and, also, in accordance with a sug- 

 gestion from the Berlin committee, every 

 day at Greenwich noon. It is very desir- 

 able that there should, if possible, be a 

 series of meteorological observations to the 

 south of the 74th parallel. 



11. As regards magnetic work and me- 

 teorological observations generally, you will 

 follow the program arranged between the 

 German and British committees, with the 

 terms of which you are acquainted. 



12. Whenever it is possible, while at sea, 

 deep-sea sounding should be taken with 

 serial temperatures, and samples of sea water 

 at various depths are to be obtained, for 

 physical and chemical analysis. Dredging 

 operations are to be carried on as frequently 

 as possible, and all opportunities are to be 

 taken for making biological and geological 

 collections. 



13. Instructions will be supplied for the 

 various scientific observations ; and the 

 officers of the expedition will be furnished 

 with a manual, prepared and edited by Dr. 

 George Murray, on similar lines and with 

 the same objects as the scientific manuals 

 supplied to the Arctic expedition of 1875. 



14. On leaving this country you are to 

 proceed to Melbourne, or Lyttelton (Christ- 

 church), New Zealand, touching at any 

 port or ports on the way that you may con- 

 sider it necessary or desirable to visit for 

 supplies or repairs. Before leaving your 

 base station you will fill up with live stock, 

 coal, and other necessaries ; and you will 

 leave the port with three years' provisions 

 on board, and fully supplied for wintering 

 and for sledge travelling. 



15. You are to proceed at once to the 

 edge of the pack and to force your vessel 

 through it to the open water to the south.
