 mottled aspect. H. filled up the notches with feebler nebu- 

 losity projecting on either side so as to complete an ellipse, or 

 possibly an elliptical ring, at right angles to the direction of 

 the two bright lobes. The longest diameter he found 7' or 8'. 

 He considered it not resolvable, but perceived in it four stars of 

 12, 12 — 13, 13, and 14 — 15 mags. The S. head was a very

 resemblance to a widely-opened eye. The resolvability does
