THE WHITE VULCAN GOLF BALL. 



A NE\v rubber cored golf ball, made under the patents of 



Charles T. Kingzett, is known as the " White Vulcan. ' A 



novel feature is that the cover throughout is made of white 



.^^^^■j^. Guttapercha. Instead of being white only 



Cis^^t^'^^i^'^ii on the surface, as in the case of the paint- 



/-vtl^irf"!-'' J •p''^ ed golf balls, the material in this case is 



v.'-J'"j'j^^Q^^2;<:;^j "all white." The Kingzett balls are made 



^';^;j^'^^^jj^jt^i^i*i by the use of specially devised machinery, 



'i'-V-Xl'j'Xj^i^'' by means of which the rubber used in the 



^■^Xii^'^?^ core is wound under the highest possible 



tension. The ball here illustrated is guaranteed against all 



faults for 54 holes of play. [The Improved Golf Ball Co.,

BRODERICK'S non-slipping TIRE. 



John K. Broderick (St. Louis) has patented a pneumatic 

 tire, one form of which is illustrated herewith. The drawing 

 shows in cross section (i) the air chamber, 

 with a broad flat tread, with (2) rubber flanges 

 extending above the air chamber to fit on 

 either side of (3) a rib of the wooden rim, and 

 to engage (4) two metal flange rings, the whole 

 being held together by (5) bolts passing trans- 

 versely through the rim. The novel form of 

 tread is designed to prevent side slipping or 

 skidding. The illustration relates to a " sin- 

 gle tube " tire, but omits a view of the means 

 for inflation. In a modification of the tire an 

 inner tube is introduced by slitting the air 

 chamber longitudinally along the point of 

 contact with the rim. The method of attaching the tire ren- 

 ders creeping impossible. 



DR. TULLAR'S HOSPITAL SYRINGE. 

 This syringe was perfected more especially for physicians 

 and hospital use. The Tullar fountain bag, shown in the illus- 

 tration, has an openingat the top sufficiently large to insert the 

 hands and thoroughly wash and cleanse the inside; in fact, 

 the bag may be 

 turned insideout 

 and scrubbed, 

 which is often 

 necessary when 

 med ications 

 have been used. 

 The large open- 

 ing also facili- 

 tates quick and 

 easy filling from 

 a pitcher or 

 other vessel. The 

 lower portion 

 being pointed 

 causes a very 

 rapid discharge, 

 and also prevents 

 any sed i m e 

 from collecting 

 or remaining In 

 the bag. The soft rubber strap handle at top permits its 

 suspension from any projection, which adds much to its con- 

 venience. The outlet pipe has a full quarter inch bore, in- 

 suring a quick fijw. When using the new spiral spray irri- 

 gator, 3 quarts of water may be discharged in one minute. 

 This new irrigator is easily and comfortably inserted, and owing 



to the peculiar form of spiral ribs, it is self holding, and keeps 

 the folds of the vagina dilated, permitting the 30 needle-spray 

 jets from the central tube to reach every part of the passage at 

 once. Thorough cleansing is quite necessary before examina- 

 tions or operations. The peculiar spiral form of the irrigator 

 ribs, surrounding the central tube of spirally arranged spray 

 jets, causes the fluid to discharge in all directions, which simul- 

 taneously comes in contact with the entire dilated surfaces. 

 This is of great advantage when applying hot water or medi- 

 cated injections. The enema pipes have three outlets arranged 

 obliquely which permits of the pipe end being perfectly smooth 

 and rounded. [The Seamless Rubber Co., New Haven, Con- 

 necticut.]

THE NEW MEXICAN TARIFF LAW. 



Following the new monetary law of Mexico, effective since 

 May I last, by which the gold standard was adopted, fixing as 

 the unit the peso, equivalent to 49.8 cents United States cur- 

 rency, and the resulting lower and more steady rate of foreign 

 exchange, a new customs tariff schedule was promulgated, and 

 this took effect September i, 1905. The following items com- 

 prise the references to rubber manufactures in the new sched- 

 ule, the rate being specified (1) in pesos per kilogram (legal 

 weight) and (2) the equivalent in United States gold per 100 

 pounds, the latter figures being supplied by The India Rubber 

 World :

By " legal weight " is meant the weight of the goods together 

 with that of their interior packings — wrappers or the like — 

 being enclosed in the outer packing case in which imported. 

 No account is taken of the weight of the outer packing case 

 where such is used. The former provision relating to a free 

 zone 20 kilometers wide along the northern boundary of Mex- 

 ico, in which imports were subject to only lo per cent, of the 

 regular duties so long as they remained within the zone, has 

 been abolished.
