WHIST OK BUMBLEPUPPy.* 

 We are rejoiced to see a new edition of this capital little book, 

 sparkling with fun and replete witli sound whist sense. Some 

 readers who complain that they cannot see where the wliist ends 

 and the fun begins may be comforted by learning that the whist 

 ends on the last page, while the fun begins on the title-page. Such 

 readers should parse carefully good Colonel Newcome's "emollunt " 

 and " .sinuisse,'' especially the last. It will do them good. We are 

 pained to find that " Pembridge " does not recognise the real reading 

 of two oft-misquoted lines of Shakespeare. The Bard of Avon must, 

 of course, have written : — 



" Twigs in the trees ; stones in the running brooks ; 

 Sermons in books ; something in everything." 

 Tliis is sound sense. 



THE FACE OF THE SKY FOR APRIL. 



By F.E.A.S. 



HE sun is as destitute as ever of interest as a tele- 

 scopic object, spots being small and occurring at 

 rarrr intervals. The zodiacal light may still be 

 detected after sunset at the beginning of the 

 month. The night sky is sliown on map iv. of 

 " The Stars in their Seasons." IMinima of Algol 

 occur at llh. .'iGm. P.M. on the lltb, and at 

 8h. 4.5m on the 17th ; as also at other times in- 

 convenient for tlie observer. Mercury is a morn- 

 ing star throughout the whole month, and is not very well placed 

 for observation. He may be detected with the naked e\'e in the 

 east just before sunri.^e towards the end of the month. Venus is 

 an evening star, and is a splendid object in the W. by N. after dusk. 

 In her passage through the sky this month, she will pass between 

 the Hj-ades and the Pleiades (" The Stars in their Seasons," map i.). 

 Mars is quite invisible. Jupiter may be seen all niglit long. He is 

 in opposition to the sun on the 21st ; but unfortunately his soutli 

 declination precludes the very finest definition of tlie details on his 

 surface in the telescope. He will be found to the south of 

 K Virginia (" The Stars in their Seasons," map v.). The phenomena 

 of his .satellites, visible before Ih. A.M., are now becoming decidedly 

 more numerous. On April 3rd, satellite II. will disappear in eclipse 

 at lOh. 54m. 12s. P.M. On April ."jth, the egress of the same satellite 

 from the face of the planet will happen at i)li. 10m. P.M. Tlien at 

 llh. 3!?m. 48s. satellife I. will be eclipsed. On the Gih, the transit 

 of satellite I. will begin at 9h. 2m. P.M. Its shadow, preceding it, 

 will leave Jupiter's opposite limb at lOli. 68m., the satellite itself 

 passing off at lUi. 13m. On the Sth, satellite III. will disappear in 

 eclipse at 8h. .54 m. 32s., to reappear from occultation at llh. 41m. On 

 the 12th, .satellite II. will enter on to Jupiter's face at 8h. 54m. P.M. 

 Its shadow will leave the opposite limb at llh. 2m., and tlie satellite 

 casting it at llh. 24m. On the 18th, the ingress of the shadow of 

 satellite I. begins at 10b. 3om. P.M., and that of the satellite itself 

 at lOh. 46m. The shadow leaves Jupiter's opposite limb at 

 12h. 47m., and the satellite at 12h. 57m. On the 14th, satellite I. 

 will be occulted at lOh. 15m. P.M. On the 15th, .satellite III. will 

 be eclipsed at 12h. 52m. 39s. P.M. On the lllth, the shadow of 

 satellite II. will begin its transit at 11 o'clock, as will the satellite 

 itself 6 minutes later. On the 20th, the shadow of satellite I. enters 

 on the planet's limb at ] 2h. 29m. P.M., and satellite I. follows it 

 one minute later. On the 21st, satellite I. will be occulted at 

 9h. 47m. P.M., to reappear from eclipse at llh, 57m. 4s. On the 

 22nd, the satellite I. will leave the disc of the planet at 9h. 8m. P.M., 

 as will its shadow at 9h. 10m. On the 2Gth, the shadow of 

 .satellite III. will pass off .Jupiter's face at Sh. 31m. p.m. On the 

 28th, satellite II. will reappear from eclipse at lOh. 32m. 16s. P.M., 

 and satellite I. be occulted at llh. .30m. On the 29th, the ingress 

 of satellite I. will occur at 8.40 P.M., and that of its shadow at 

 8h. 62ra. The satellite will quit Jupiter's opposite limb at lOh, 52m. ; 

 its shadow at llh. 5m. Lastly, on the 30th, satellite I. will 

 reappear from eclipse at 8h. Tjm. 10s. p M. Saturn is stiU an 

 evening star, but is now approaching the west. He travels 

 during April from a point to the NE. of f Geminorum 

 towards S (" The Stars in their Seasons," map ii.). By the end 

 of the month he will be quite close to S Geminorum. Uranus 

 will be found between 2° and 3° to the south of y Virginis 

 (" The Stars in their Seasons,'' map v.). The Moon enters her first 

 quarter at Ih. 52-8m. P.M. on the 1st, is full at ,5h. 38-9m. A.M. on 

 the 7th, enters hfrlast quarter at 4h. 3*8m. A.M. on the ]5th, and is 

 new at 8h. 53-2m. A M. on the 23rd. She will enter her first

quarter — for the second time this month — at llh. 0'4m. p.m. on the 

 30tli. High tides may be expected about the 7th. Occultations of 

 stars by tlie Moon at convenient hours during the present month are 

 fairly numerous, but in each case the star is a small one. Beginning 

 with the 2nd, B.A.C. 2731, a star of the 6ith magnitude will 

 disappear at tlie Moon's dark limb at 9h. 20m. p.m. at an angle of 

 111" from her vertex. It will reappear at her bright limb at 

 lOh. 30m. P.M. at an angle from her vertex of 288°. On the 7th, 

 46 Virginis, a 6th mag. star, will disappear at her bright limb 

 at 9h. 23m. P.M. at an angle from her vertex of 351°. It will 

 reappear at her dark limb at lOh. 6m. P.M. at a vertical angle 

 of 275°. At lOh. 59m. on the same night another 6tli mag. 

 star, 48 Virginis, will disappear at ihc bright limb at an angle 

 of 28° from the vertex of the Moon. Its reappearance at 

 12h. 2m. at the dark limb occurs at a vertical angle of 271°. 

 When the Moon rises on the 9th, .she will already have 

 occulted I' Libra?, a 6th mag. star. It will reappear at her 

 dark limb at 8h. 38m. P.M., at an angle of 173° from her vertex. 

 On the 25th, 48 Tauri, a star of the 6th magnitude, will dis- 

 appear at the dark limli at 9h. P.M., at an angle of 85° from the 

 vertex of the Moon. The Moon will have set ere It reappears. On 

 the 29th, 8 Cancri, a 6th-magnitude star, will disappear at the dark 

 limb 18 minutes after midnight, at a vertical angle of 199°, but 

 the Moon will be setting when it reappears. On the 30th, 54 Cancri, 

 of the 6ith magnitude, will dis.appear at the dark limb at 9h. 3Gm. 

 P.M., at an angle of 74° from the lunar vertex. Its reappearance at 

 the bright limb happens <at lOh. 27m., at an angle from the vertex 

 of 330°. Lastly, on the same night, at 12h. 25m., o' Cancri, a 6th- 

 magnitude star, will disappear at the Jloon's dark limb, at an angle 

 of 172° from her vertex, reappearing 53 minutes after midnight at 

 her bright limb, at a vertical angle of 286°. When these notes 

 begin tlie Moon is in Gemini (" The Seasons Pictured," plate xxiv.), 

 but she leaves this for Cancer at 4 P.M. on the 2nd. She quits 

 Cancer in turn for Leo at midnight on tlie 3rd. Her passage 

 tlirough Leo occupies her until 1 P.M. on the 6th, at which hour 

 she crosses into Virgo (" The Seasons Pictured," plate xxv.). She 

 does not leave Virgo until 8h. 30m. A.M. on the 10th, when she 

 enters Libra ("The Seasons Pictured,'' plate xxvi.). In her 

 passage across Libra, she arrives at 1 a.m. on the 11th on 

 the boundary of the narrow northern spike of Scorpio. By 

 10 o'clock the same morning she has traversed this, and passed 

 into Ophiuchus. Her passage through the southern part of 

 this constellation is completed at 2h. 30m. AM. on the 

 13th, when she crosses its confines into Sagittarius. At noon 

 on the 15th, she quits Sagittarius for Capricornus ("The Seasons 

 Pictured," plate xxi.). Skirting the rather tortuous boundary be- 

 tween Capricornus and Aquarius, she does not fairly enter the last- 

 named constellation until 4h. P.M. on the 17th. She is travelling 

 across Aquarius until 8h. P.M. on the 19th, when she enters Pisces 

 (" The Seasons Pictured," plate xxii.). Tr.avelling through Pisces, 

 she arrives at midnight on the 22nd at the dividing line of the 

 northern prolongation of Cetus. She remains in this part of Cetus 

 until 3h. P.M. on the 2.8rd, when she leaves it for Aries ("'The 

 Seasons Pictured," plate xxiii.). She only takes until 7h. 30m. P.M. 

 on the 24th to cross Aries and enter Taurus. In her journey 

 through Taurus she arrives at 4h. P.M. on the 27th on the boundary 

 of the northern projection of Orion. When she has travelled 

 through this by 4 o'clock the next morning, it is to emerge in 

 Gemini (" The Seasons Pictured," plate xxiv.). She remains in 

 Gemini until lOh. p.m. on the 29tli, when she crosses into Cancer. 

 She is still in Cancer at midnight on the 30th.
