LAWS RELATING TO ANIMAL INDUSTRY. 



The capacity of the bulb up to the junction of the neck shall 

 not be less than forty-five cubic centimeters. The shape of the 

 bulb may be either cylindrical or conical with the smallest 

 diameter at the bottom. If cylindrical, the outside diameter 

 shall be between thirty- four and thirty-six millimeters; if 

 conical, the outside diameter of the base shall be between 

 thirty-one and thirty-three millimeters, and the maximum 

 diameter between thirty-five and thirty-seven millimeters. The 

 charge of the bottle shall be eighteen grams. The total height 

 of the bottom shall be between one hundred fifty and one hun- 

 dred sixty-five millimeters (five and seven-eighths and six and 

 one-half inches) . 



(&) Two types of bottles shall be accepted as standard 

 cream test bottles, a fifty per cent nine gram long-neck bottle, 

 and a fifty per cent eighteen gram long-neck bottle. 



Fifty per cent, nine gram, long-neck bottle: Graduation 

 The total per cent graduation shall be fifty. The graduated 

 portion of the neck shall have a length of not less than one 

 hundred twenty millimeters (four and three-quarters inches). 

 The graduation shall represent five per cent, one per cent and 

 five-tenths per cent. The five per cent graduations shall extend 

 at least half way around the neck (to the right). The five- 

 tenths per cent graduations shall be at least three millimeters 

 in length and the one per cent graduations shall have a 

 length intermediate between the five per cent and the five-tenths 

 per cent graduations. Each five per cent graduation shall 

 be numbered, the number being placed on the left of the scale. 



Neck The neck shall be cylindrical and of uniform internal 

 diameter throughout. The cylindrical part of the neck shall 

 extend at least five millimeters below the lowest and above the 

 highest graduation mark. The top of the neck shall be flared 

 to a diameter of not less than ten millimeters. 



Bulb The capacity of the bulb up to the junction of the 

 neck shall not be less than forty-five cubic centimeters. The 

 shape of the bulb may be either cylindrical or conical with 

 the smallest diameter at the bottom. If cylindrical the outside 

 diameter shall be between thirty-four and thirty-six milli- 

 meters; if conical, the outside diameter of the base shall be 

 between thirty-one and thirty-three millimeters and the maxi- 

 mum diameter between thirty-five and thirty-seven millimeters. 



The charge of the bottle shall be nine grams. All bottles 

 shall bear on top of the neck above the graduations, in plain 

 legible characters, a mark defining the weight of the charge to 

 be used (9 grams). 



The total height of the bottle shall be two hundred ten to 

 two hundred thirty-five millimeters (eight and one-fourth 

 to nine and one-quarter inches) and the maximum error in 

 the total graduation or in any part thereof shall not exceed 

 fifty per cent of the volume of the smallest unit of the gradua- 

 tion.
