POPULAR SCIENCE REVIEW. 
chief defects of albumen. A second, from America, concerning which there 
has been much extraordinary trumpeting, and which is called “ Porcelain 
Paper,” in consequence of its hardness, whiteness, and freedom from the 
objectionable glare of albumen. A third, in America, by Mr. Follet, 
concerning which we have as yet been able to gather no special facts. 
Photographs and Booh Illustration. — The Legislature of Massachusetts has 
been the means of publishing a supplement to the late Professor Hitchcock’s 
“ Geology of New England,” illustrated by photographs from nature. This 
book will be a valuable addition to scientific libraries. A cheap medical work 
of great interest on the application of phenic acid in medicine, illustrated with 
photographs, has been published in Paris. Mr. Stephen Ay ling, of Oxford- 
street, is publishing a most valuable collection of beautiful photographs, from 
sketches by A. Welby Pugin, in which some of the greatest difficulties to be 
met with in the art of photographic reproduction have been encountered and 
surmounted with consummate skill and ability. Professor Hoffman has 
recently issued an excellent manual of “ Modem Chemistry,” illustrated from 
photographs, and Mr. A. W. Bennett is also issuing some beautiful photo- 
graphic gift-books. This branch of art will doubtless receive a new and 
extraordinary impetus from the introduction of Mr. Walter Woodbury’s new 
process of printing in relief. At the last meeting of the London Photographic 
Society, one of the most crowded we have yet had the pleasure of attending, 
the whole of this process was gone through before those present, and elicited 
universal marks of approbation, although some of the members appeared to 
be unusually slow in comprehending the simple details of this beautiful 
process, and rendered Mr. Woodbury evidently nervous by their persistency 
in repeating the same questions, and misunderstanding the clear and explicit 
replies they received. 
Astronomical Photography. — The partial eclipse of the moon on the 4th 
of October was chronicled by Mr. De la Rue in a series of seventeen photo- 
graphs. A late eclipse of the sun was photographed by Mr. Thomas P. 
Shepard, of Philadelphia, with considerable success. The American corre- 
spondent of The British Journal of Photography, describing this photograph, 
says, “ The sun itself appears as a small bright crescent, surrounded by a 
dark circle of at least twice its own diameter. That, again, is in the centre 
of an irregular mass of very bright clouds, which are themselves surrounded 
with darker ones. The whole effect is exceedingly curious, and it is very 
difficult to account for the dark circle immediately around the sun, which is 
not concentric with it, but with that part of the sun’s limb which is farthest 
from the moon. The light crescent has a pretty well-defined border, but the 
darker circle is much less defined.” Mr. A. Brothers exhibited early in 
October, at the Photographic section of the Literary and Philosophical 
Society of Manchester, a valuable series of instantaneous photographs, taken 
during the progress of the recent eclipse of the moon on October 4th. These 
were twenty in number. The first was taken at 8*45, when the moon was 
nearly full, and the last at 12 - 45, the remainder having been exposed at 
regular intervals of fifteen minutes. These were taken with an equatorial 
telescope of five inches aperture and six feet focal length, with clockwork 
driving arrangement ; and considerable time was occupied in calculating the
