brought to light the celebrated Fountain of Juturna, so highly 

 appreciated by the Romans for the salubrity of its waters. A 

 spacious rectangular construction in tufa work (opus reticulatiwi) 

 of the Republican epoch encloses the spring. The construction 

 is internally covered with marble slabs. A short flight of steps, 

 which leads to the spring, has been rebuilt at a much later date. 

 The water gushes out abundantly at the present time, fresh and 

 clear. The following interesting monuments were found in the 

 room which encloses the spring : — (i) A marble altar the four 

 faces of which bear sculptures of the Dioscuri, of Jupiter holding 

 the sceptre and thunderbolts, of Leda with the swan, and 

 of a feminine figure, probably Vesta or Diana Lucina, holding 

 a long torch. The association of the fountain of Juturna 

 with the sanctuary of the Vestals is a well-known fact. (2) A 

 life-sized statue of .^sculapius in white marble (now standing at 

 his shrine) ; this statue was placed there on account of the 

 health-giving qualities of the waters of the fountain. (3) A white 

 marble bust of Jupiter, very well preserved. (4) A splendid 

 head and body of a horse in Pentelic marble, conjectured to be 

 the work of a Greek artist of the fifth century B.C., and to have 

 belonged to a group representing Castor and Pollux and their 

 horses. (5) A torso of Apollo in Greek marble, archaic in style, 

 but clearly a Roman imitation, perhaps of the time of Hadrian. 



Mr. Thomas Thorp exhibited photographs of the spectrum 

 of the new star in Perseus, showing the bright lines very clearly, 

 and he mentioned that the star has now faded to about the fifth 

 magnitude. 



Mr. Thorp also described a variation in the ordinary arrange- 

 ment of a star spectroscope, which he has devised. 



Mr. J. R. Hardy read a paper on " The Macro-Lepi- 

 doptera of Sherwood Forest," which was communicated 

 through Mr. Hoyle. 



The paper is printed in full in the Memoirs.
