26 FOSTER'S LIST OF REFINED AND IMPROVED 



LINES. 



THE ORIGINAL "INDESTRUCTIBLE" WATERPROOF SILK, 



AND THE 



NEW IMPROVED METAL CENTRED "ACME" LINES. 



MORE than forty years have elapsed since the Eight-plait Water- 

 proof Silk Line was first invented. Its use has become in 

 the meantime almost universal. The success of the original 

 waterproof line as is the case with all genuine improvements 

 has been the signal for the launching of numerous, more or less 

 unsatisfactory, imitations. In this instance they invariably fail on 

 the score of durability. This, owing to the fact of their having 

 been steeped in some deleterious mixture,* which, if it does not 

 entirely rot the silk in a few months, will be owing to its having 

 been rubbed or "spelched " from the line by the friction of the 

 rings and the action of the water before that operation could be 

 thoroughly effected. 



The original waterproof dressing, first introduced by the late 

 David Foster, in conjunction with the late Henry White, Professor 

 of Chemistry, wears almost indefinitely, and since the principle 

 of plaiting sixteen silk strands in lieu of half that number has 

 been introduced, their wear-and-tear resisting qualities have been 

 increased. To distinguish from the host of unreliable imitations, 

 the original line is now termed the " Indestructible." 



Our recent development of the above is the " Improved Sixteen- 

 plait Double Dressed Acme," which line has a very fine gimp 

 core, which is gilded to avoid all possibility of corrosion, and is in 



* The prevailing practice is to boil the silk in a seething compound of 

 oils, &c.
