The receiver, C, may be cleaned in a similar manner, although it 

 is advisable to occasionally clean it with a hot solution of washing- soda, 

 followed by alcohol and this again by a little of the reagent. 



We could have made our directions very brief had it seemed advis- 

 able to do so, but we preferred making them sufficiently full and explicit 

 to cover and make clear all points in connection with the test, and thus 

 insure accurate results. This course will, we believe, be appreciated 

 by users of the test. 



After making a few tests the simplicity of the whole operation will 

 be apparent. 



ADDENDA. 



Experience has shown us that the balance works better with the 

 heavy part of the counterpoise below instead of above the beam, and 

 we have altered it accordingly. Place the counterpoise on the beam so 

 that it practically balances the cup. Finer adjustments after this has 

 been done are made by means of the nut on the screw that projects 

 beyond the beam. 



Keep the glass stopper of the graduated receiver vaselined. 



Experience with both a threaded and a friction joint on the cup has 

 proven that the latter works the better. 



When testing curd or cheese heat more slowly than with butter, 

 taking from seven to eight minutes to drive the moisture off. 



The reagent used in this test is amyl acetate (technical variety), and 

 should be obtainable from any reliable druggist at about one dollar per 

 pound. It should be put in the cup and tested for moisture, and, if neces- 

 sary, freed from the same before using. 



PRICE OF THE MOISTURE TEST. 



The apparatus may be obtained from us at the following prices : 

 complete outfit, including an 8 oz. bottle of reagent, $13. Travelling 

 case for outfit, $2 additional. (This is furnished only when specially 

 ordered.) In cases where the balance for weighing out samples is not 

 wished, a deduction of $3.50 from the above price is made. We recom- 

 mend the use of the balance supplied, however, as it has a counterpoise 

 to balance the cup, and is otherwise specially fitted for the work. 



Individual parts may be obtained at anv time at reasonable prices. 

 Customers in Canada will be charged $14 for the complete outfit, as parts 

 of it have to be imported and duty paid thereon. 



All orders, unless accompanied by the price, sent C.O.D. 



Send all orders for apparatus to Supt. of Eastern Dairy School, 

 Kingston, Ontario.
