Valuable Works 
skilful, manufacturing, as well as an able, scientific chemist, enjoying the ffiub 
tiplied advantages afforded by the metropolis of the greatest manufacturing na- 
tion on earth, was eminently qualified for so arduous an undertaking, and the 
popularity of the work in England, as well as its intrinsic merits attest the 
fidelity and success with which it has been executed. In the work now offered 
to the American public, the practical character of the Operative Chemist has 
been preserved, and much extended by the addition of a great variety of origi- 
nal matter, by numerous corrections of the original text, and the adaptation 
of the whole to the state and wants of the Arts and Manufactures of the United 
States; among the most considerable additions will be found full and extended 
treatises on the Bleaching of Cotton and Linen, on the various branches of Ca- 
lico Printing, on the Manufacture of the Chloride of Lime, or Bleaching Pow- 
der, and numerous Staple Articles used in the Arts of Dying, Calico Printing, 
and various other processes of Manufacture, such as the Salts of Tin, Lead, 
Manganese, and Antimony; the most recent Improvements on the Manufacture 
of the Muriatic, Nitric, and Sulphuric Acids, the Chromates of Potash, the 
latest information on the Comparative Value of Different Varieties of Fuel, on the 
Construction of Stoves, Fire-places, and Stoving Rooms, on the Ventilation of 
Apartments, &c. &e. To make room for the additional practical matter, and 
not to enhance the price of the work to the American reader, between two and 
three hundred pages of the theoretical or doctrinal part of the original work 
have been omitted; indeed, most of the articles on the theory of chemistry, such 
as Electricity, Galvanism, Light, &e. which have little or no immediate ap» 
S lication to the arts, and which the chemical student will find more fully 
iscussed in almost every elementary work on the science, have been either 
wholly omitted or abridged. Many obsolete processes in the practical part of 
the work, used in some instances, the description of arts not practised, ana from 
their nature not likely to be practised in the United States, have also been 
omitted; in short, the leading object has been to improve and extend the prac- 
tical character of the Operative Chemist, and to supply, as the publishers flatter 
themselves, a deficiency which is felt by every artist and manufacturer, whose 
processes involve the principles of chemical science, the want of a Systematic 
Work which should embody the most recent improvements in the chemical 
arts and manufactures, whether derived from the researches of scientific men, 
or the experiments and observations of the operative manufacturer and arti- 
zans themselves.

XXVIII. ARNOTT’S ELEMENTS of PHYSICS. 
Vol. IT. Part I. containing’ Light and Heat. 
“ Dr. Arnott’s previous volume has been so well received, that it has almost 
banished all the flimsy productions called popular, which falsely pretend to strip 
science of its mysterious and repulsive aspect, and to exhibit a holyday apparel. 
The success of such a work shows most clearly that it is plain, but sound know- 
ledge which the public want .”— Monthly Review.

XXIX. ELEMENTS of PHYSICS, or NATU- 
RAL PHILOSOPHY, GENERAL and MEDICAL, explained

XXX. MORALS of PLEASURE, illustrated by 
Stories designed for Young Persons, in 1 vol. l2mo. 
“ The style of the stories is no less remarkable for its ease and gracefulness, 
than for the delicacy of its humour, and its beautiful and at times affecting sim- 
plicity. A lady must have written it— for it is from the bosom of woman alone, 
that such tenderness of feeling and such delicacy of sentiment— such sweet les- 
sons of morality— such deep and pure streams of virtue and piety, gush forth to 
cleanse the juvenile mind from the grosser impurities of our nature, and prepare 
the young for lives of usefulness here, and happiness hereafter. We advise pa- 
rents of young families to procure this little book— assuring them that it will 
have a tendency to render their offspring as sweet as innocent, as innocent as
