[Illustration: 403 404 405] POSTCARDS AND POSTMARKS. The remaining illustrations, added as this work is being sent to press, supplement the philatelic records of the present war, as already outlined in the earlier chapters. _Fig._ 406 is the original issue of the French military postcard, on thin green card. _Fig._ 407 is also French, printed on a thicker Silurian card. _Fig._ 408 is a German field postcard (medium white) despatched by a British prisoner of war in the English Lager at Sennelager. A few additional naval postmarks are also shown (_Figs._ 409-413). _Fig._ 409 appears to be in the design of an "Iron Cross" (!) _Fig._ 414 is a mark used by the censor in handling registered mail, and 415 is on correspondence originating at a depot for convalescent horses. _Figs._ 416-420 are various types of censor marks, No. 419 being a Dutch one on a letter posted at Maastricht. At the time of going to press we have noted British military censor marks up to No. 1739. We are also able to state definitely that _Fig._ 85B (Chapter II.) is a field postmark of the Indian Expeditionary Force in France.

The only intentional changes to the text are where typographical errors have been corrected as follows: Page 5, "page 47" changed to "page 49" (in Table of Contents: Chapter IV ... page 49.) Page 5, "page 77" changed to "page 75" (in Table of Contents: Chapter VI ... page 75.) Page 5, an Appendix starting on p. 122 is not listed in the Table of Contents. Page 32, Figure 69 originally on page 32 moved to page 33; appears as illustration for HTML version and is transcribed as text for this Plain Text version. Page 33, note hand-written correction to the poster (Figure 69) "stamps" should read "letters" (unpaid and unfranked letters will also run the risk of misdelivery.) Page 36, missing closing parenthesis added "(Fig. 77)". Page 45, there is no Figure 123. Page 45, "129" changed to "128" ("Figs. 126-128".) Pages 57 & 58, duplicate use of figure numbers 167 and 168. Page 59, "Womens'" changed to "Womens'" (the Imperial Women's Patriotic Union.) Page 70, Figure 221 appears as illustration for HTML version and is transcribed as text for this Plain Text version. Page 76, "Fraulein" changed to "Fräulein" (an actress Fräulein Anna Führing). Page 87, suspected error in original unchanged: "susceptibilities" for "sensibilities" (which gave offence to Muslim susceptibilities). Page 103, "incriptions" changed to "inscriptions" (the inscriptions on which read "Liberty or death...") Page 108, in the transcription of the overprint "HALILITADO POR LA JUNTA REVOLUCIONARIA" it is unclear whether "HALILITADO" is an error for "HABILITADO" in the typesetting or in the original overprint.
