Ixxii Instructions to Scientific Observers, ^c, 



14. All views should be numbered and dated witb. tbe time of 

 day, the position whence they were taken marked on the map, and 

 the compass bearing, and estimated distance given of the extreme 

 points embraced in each. 



ZOOLOGY. 



The Zoologist, in addition to all general observations which he may 

 be able to make on all classes of animals that may occur to him, 

 illustrated by sketches, is particularly required, to ascertain, when 

 possible, the fishes, shells, or articulata occurring in any stagnant or 

 running waters met with, as these are of the highest interest in con- 

 nection with questions of the geographical distribution of animals. 



No duplicate specimens that might encumber the party need be 

 collected. Of fossil animals, if any should be noted, it would be 

 very desirable tojsecure characteristic specimens. The larger fishes 

 may be skinned, by the removal of one-half of the fish, leaving the 

 fins of the mid-line perfect ; if then washed with solution of corrosive 

 sublimate in spirit, the specimen can be packed flat between papers 

 without injury. 



The soft Annelida and small Crustacea, as well as the soft parts of 

 Mollusca, should be inclosed in vessels of spirits, the specimens 

 separated by portions of linen cloth to prevent their being injured by 

 shaking. Paper labels, written with black lead pencil, will remain 

 uninjured with specimens so packed. As a general rule, every 

 specimen collected should receive one of a consecutive series of num- 

 bers (irrespective of the natural series of the objects), by which it 

 should be indicated in the journal of the day, in which all particulars 

 observed about it or illustrative sketches should appear. 



In case a specimen of actually or doubtfully the same species 

 be obtained for the second or third time, at some subsequent dates 

 from its first entry in the journal, there is no objection to its receiv- 

 ing a new number in connection with any additional observations 

 which may be made, in cases where loss of time would result from 

 endeavouring to ascertain the first number applied to the series. 



Of Mammalia, the nocturnal ones, as bats, and the small murine 

 forms, are the most interesting, and should receive particular attention. 



No opportunity should be lost to obtain through the oflicer in 

 charge of depots, or through reconnoitering parties, additional 

 specimens of rocks, fossils, minerals, and natural history. 



It will be of vast importance to ascertain, as extensively as possible, 

 what relation the vegetation bears to its geological formation. 



BOTANICAL OBSERVER. 



For the purpose of elucidating to the fullest extent the phytology 

 of any part of Australia to be explored by the Victorian expedition,
