described (Fig. 2) is 

 similar to the regu- 

 lar milk bottle, and 

 also to the Connec-

 bottle, except that 

 the base portion is 

 made of such size 

 as to avoid using 

 an acid measure. 

 The base is made to 

 hold about 38 cubic 

 centimeters up to 

 the neck and after 

 the cream is meas- 

 ured in, the re- 

 quired amount of 

 acid can be added 

 by filling the bottle a- 

 nearly to the neck 

 or to the point A 

 shown in the cut. 

 The neck portion is 

 large enough to 

 carry 25 per cent. 

 of fat and is grad- 

 uated to one-half 

 of one per cent, and can be easily read to one-quarter of one 

 per cent. Each per cent, is numbered. Although one cannot 

 read so closely with this as with the bulb neck bottle (described 

 in Bulletin No. 3, Second Series, Maine Experiment Station), 

 which was designed to test both milk and cream, one can read 

 fine enough for all practical purposes. On account of the neck 

 being larger and shorter, this bottle is more easily cleaned than 

 either of the older forms; it is less liable to breakage, and by 

 using the method previously given for milk a test can be made 

 more rapidly. Twenty-five per cent, was fixed upon as the
