6 Valuable Works 



skilful, manufacturing, as well as an able, scientific chemist, enjoying the mul- 

 tiplied advantages afforded by the metropolis of the greatest manufacturing na- 

 tion on earth, was eminently qualified for so arduotis 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. &c. 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, &c. which have little or no immediate ap- 



Slication 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 ef 

 the work, used in some instances, the description of aits not practised, and from 

 their nature not likely to be practised in the United States, have also been 

 omitted; in short, the leading object kas been to improve and extend the prac- 

 tical character of the Operative Chemist, and to supply, as the publishers natter 

 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. II. 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 

 independently of TECHNICAL MATHEMATICS, and con- 

 taining New Disquisitions and Practical Suggestions. By 

 NEILL ARKOTT, M. D. First American from the third London 

 edition, with additions, by ISAAC HATS, M. D. 



%* Of this work four editions have been printed in England in a very short 

 time. All the Reviews speak of it in the highest terms. 



XXX. MORALS of PLEASURE, illustrated by 

 Stories designed for Young Persons, in 1 vol. I2mo. 



" The style of the stories is no less renoarkable 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 a*
