for the uneven numbered groups: 
sin 5 (1488 š + pz) 
sin (1488 Е + px 
The variation being double-periodic, the value me 
to be taken twice as large as that adopted in the forme 
problem, in order to correspond with an increase of about 
hours in the arrangement; to ? the ten positive values 
have been assigned. For simplicity’s sake I took: 
sin (2na + € + 269 x 24.8 ds, i
