NEW   UmPs, on Hungerford Bridge. 
There is so much novelty and 
ornamental fitness in the arrangement 
of the lamp-posts which have lately 
been erected on Hungerford Suspen- 
sion Bridge, that we have thought it 
might interest the trade to call their 
attention to them. Obviously this 
arrangement would only be suitable 
where the height of the passage below 
need not be great. It is almost tan- 
tamount to making one lamp in the 
centre do the work of two at the 
sides. The only part we do not like 
of this design is the imitation rope 
affecting to bind up the lamp. It is 
bad in taste and principle.

DYEING AND CALICO-PRINTING. By E. A. Parnell.-Taylor, Walton, and Maberly,
London. 
ABOVE all the manufactures of this kingdom those of cotton are the most extensive
and valuable; none demonstrate more completely the intimate and successful
con- 
nexion which may always be formed between scientific theory and skilful practice.
It is, however, to be noted that we, the people most practical in the Whole
world in 
the production of cotton manufactures, have said very little about it. The
French, on 
the contrary, whose works in extent at least bear no comparison with our
own, have 
said a good deal, which is ably set forth in the admirable treatise of M.
Persoz, 
"L'Impression des Tissus." Those of our readers who may already
know Mr. Parnell's 
"Chemistry applied in Manufactures and Arts," will recognise the
book now pub- 
lished as a reprint from that work, with improvements. The present work for
its 
extensive details is about an eighth of the size of M. Persoz's; but, for
its compass, 
is tolerably complete, informing, and useful. It comprehends treatises on
the His- 
tory of Dyeing, and Calico-Printing; the Properties of Vegetable Colouring
Matters; 
Nature of Dyeing Processes; and of Calico-Printing Processes. On the antiquity
of 
dyeing Mr. Parnell relates as follows:- 
"In the East Indies, in Persia, in Egypt, and in Syria, the art of dyeing
has been 
successfully practised from time immemorial. In the books of the Pentateuch
fre- 
quent mention is made of linen cloths dyed blue, purple, and scarlet, and
of rams' 
skins dyed red; and the works of the tabernacle, and the vestments of the
high-priest, 
were enjoined to be of purple. 
" The place of antiquity where dyeing was most extensively carried on,
as the 
general business of the inhabitants, was probably Tyre, the opulence of which
