ITo. 175. T Cephei. — Erom four observed maxima, 1882-1885, 
[!nott deduces a period of 392*0 days with Epoch. 1884, March 6 ; and 
rom 5 minima, 1881-1885, a period of 385-4 days with Epoch 1883, 
August 7. The elements derived from the maxima give much smaller 
esiduals than those derived from the minima. The increase of light 
s slower than the decrease. The star has a fine spectrum, with dark
