SCIENTIFIC SUMMARY.

planet, and were attentively and ably observed by Mr. Dawes.” In 1859 
the flocculent cloudy appearances resembling port-holes in the principal belts 
were beautifully drawn by Sir J. Keith Murray. In 1860-61 again, Professor 
Airy, speaking of the great equatorial, says, il It has been employed to a? 
considerable extent in the preparation of delineations of Jupiter and Mars.. 
The former of these planets has exhibited in the last year some appearances 
never before recorded ; and it has appeared very desirable to register as soon 
as possible anything which seems to indicate a change in the constitution of 
that great body.” Mr. Carpenter therefore made, during that year, a series 
of most careful drawings, showing all the flocculent port-holes and the- 
reddish colour of the equatorial region, bright egg-shaped spots, and 
elliptical markings, which have been observed during the last two- 
years. 
An important feature in Mr. Ranyard’s paper is the fact that the evidence 
he adduces is taken from the recorded observations of Lassell and De la 
Rue, who are now the chief opponents of the assertion that Jupiter has 
lately changed in aspect, and, from the work done by the Greenwich equa- 
torial, n'ow said to give no evidence of change. 
We may note in this connection that the picture of Jupiter at p. 280 of 
the last number of the Popular Science Review , has been inverted by mis- 
take. The inversion is of no consequence in itself, since it simply causes 
the picture to present Jupiter in his natural instead of his telescopic posi- 
tion ; but as the comparison between this picture and others might lead to 
confusion, it is desirable that the astronomical reader should be made aware 
of the mistake. (Mr. Webb did not see the proof in situ, and is therefore- 
not responsible for the error.) 
Discovery of another Asteroid. — Another asteroid, the 115th, has been dis- 
covered by Mr. Watson, of Ann Arbor, U.S., who bids fair to rival the most 
successful asteroid seekers. 
The November Shooting-stars . — We remind our readers that the November 
shooting-stars should be looked for in the early morning hours of Novem- 
ber 13 and 14. It is not likely that a display of a marked character will be 
witnessed, but considerable interest attaches to the determination of^the 
relative richness of different portions of the system. It is not unlikely 
that stragglers, really belonging to the same system, may be seed (and known 
by their “ radiant point ”) on several days before and after November 13. 
The Planets of the Quarter . — Venus will be a morning star, attaining her 
greatest brilliancy on November 1, and reaching her greatest westerly 
elongation on December 6. Jupiter will be well placed for observation 
during the latter half of the quarter. Mars and Saturn will not be well 
placed for observation. 
‘ BOTANY. 
Transpiration of Watery Matter by Leaves. — Professor M‘Nab of the Royal 
Agricultural College, Cirencester, has published an important and lengthy? 
paper on this subject in the “ Transactions of the Botanical Society of 
Edinburgh.” The conclusions at which the Professor arrives may thus be
