The Planets for March and April. 
Mercury is not in a favourable position for observation. 
Venus became a morning star on February 10, and remains so until 
November 24. Venus is crescent-shaped at the beginning of March, and 
reaches half-moon phase on April 20. 
Mars is favourably situated for observation during March and April, 
but the planet is so far distant from the earth as to show a comparatively 
small disc. 
Jupiter is an evening star, and gradually becomes less favourably situated 
for observation. 
Saturn was in opposition on February, and is favourably situated for 
observation in March in the early evening.

(2.) A partial eclipse of the moon, June 23-24 G.M.T. Visible in New 
Zealand. 
(3.) An annular eclipse of the sun, December 3 G.M.T. Invisible in 
New Zealand. 
Long-period Variable Stars. 
The following table gives particulars of the charts of long-period vari¬ 
able stars. These charts are paper prints 8 in. by 10 in. in size, enlarged 
from photographs, to a scale of 20 in. = 1 mm. for the fainter variables,
