Viii PREFACE. 



At page v. will be found a Table of Contents, referring to the pages where 

 any particular section or class of apparatus will be found, and at page 567 an 

 extensive general Index, giving the marginal number or page for each 

 Instrument: these, combined with upwards of Thirteen Hundred "Wood 

 Engravings (a large proportion of them new), will assist the reader in searching 

 for any particular item. 



When Orders are transmitted in Foreign Languages, N". & Z. advise 

 their friends to send verbatim copies of such orders in the original language, 

 as it often occurs that where the order has been translated and copied by 

 persons unacquainted with the nature or use of the articles written for, serious 

 errors arise in the carrying out their correspondents' commands. 



Correspondents may, if preferable to them, write in French, Italian, 

 Spanish, or German. 



A liberal commission allowed to Merchants, Shippers, or Agents on large 

 transactions. Merchants favouring us with copies of their clients' orders will 

 have special quotations furnished to them if desired. 



Full and explicit instructions should accompany orders as to the Address, 

 mode of Conveyance, Shipment, Insurance, Consular Forms, and Declarations, 

 etc., etc. Foreign or Country orders must be accompanied by an adequate 

 Remittance or Order for Payment, or Satisfactory Reference in London. 



Every possible care being taken in packing Apparatus and Instruments to 

 insure safety in carriage, ibe cannot be responsible for any damage that may occur 

 in transit after the goods leave our establishment. 



The probable expense of Packing Cases, Tin or Zinc-lined, may be taken 

 at say from 5 to 10 per cent, on the value of articles of ordinary dimensions 

 and weight. Yery bulky or extremely heavy goods can. hardly be estimated 

 for ; but 1ST. & Z. will undertake that all packages, &c., shall be supplied at 

 the lowest possible net charge. 



All communications from abroad should be directed to the Chier 

 Establishment, Negretti & Zambra, Holborn Viaduct, E.G., London. 

 Letters for their Branches to be specially addressed 45, Cornhill, E.G. ; 

 122, Regent Street, W. ; or, Negretti & Zambra's Photographic 

 Department, Crystal Palace, Sydenham, S.E. 



The compilation and revision of this New Edition of our Catalogue has 

 again been entrusted by us to Mr. R. WILLATS, the Manager of our retail 

 department at Holborn Viaduct ; and we hope that both as a Price List and a 

 Book of Reference it will be found much superior to its predecessors. 



NEGEETTI & ZAMBEA.
