THE SOUTHERN NIGHT SKIES. 



N the last volume of Knowledge I began a series 

 of maps of the night skies of the southern 

 hemisphere, intended^to show them for each 

 night in the year all the year round. But 

 a series of blunders and delays on the part 

 of the engravers, and the most contradictory 

 misinterpretation of my instructions, prevented 

 me from carrying out my design. Only three maps of the 



duplicate. One map will show the stars down to the third 

 magnitude, with a few of the smaller stairs when necessary 

 to complete groups, on a black ground without any names or 

 lettering. The other will show the same stars on a white 

 ground, with the names of constellations, Greek lettering 

 for stars, and other writing and lines for guidance. Each 

 paper of the series wUl appear two months in advance, so 

 as to be in good time for readers in Australasia and Cape 

 Colony. In the first pair, accompanying this, the night 



Mai- ]a. 



NKiUT SKIES OF AUSTR.\L.\SIi, CAPE COLONY, &C., FOR JANUARY. 



series appeared, and those so late as to be scarcely of any 

 use for the purpose intended. 



I now begin the series afresh under more favourable condi- 

 tions. I propose to present the skies of the southern hemisphere 

 now, for latitude 38° south, or accurately enough for such 

 maps, foi all places between latitudes 30° and 45° south, in 



skies for January are presented. Tlie maps are for the 

 following hours : —
