breaking from his accustomed pastures, crosses a railroad track 

 in the gloom of the evening, and seeing the locomotive coming 

 with its dazzling light plunges at it to brush the locomotive 

 away ; but it is the bull and not the locomotive that disappears. 

 Now I ask you to remember this fact, that not one witness in 

 this case has said that the lactometer will not test specific gravity. 

 They all agree to that. " But it is useless," says the learned 

 professor. I say let us determine the specific gravity in the first 

 place. The public officers in this case do not propose to you the 

 lactometer as a test for anything else but specific gravity, but 

 they say that since you know what the specific gravity of good, 

 sound, commercial milk is, and must be, if the milk tested shall 

 fall below that standard on the lactometer, then it is watered. 

 Now, gentlemen, whether that be a correct conclusion or not, 

 you have heard the evidence of all these learned gentlemen who 

 have testified to the value of this test. I shall not take up your 

 time to attempt to meet the quibbles about mistakes of words 

 when they were under the very sharp fire of the cross-examina- 

 tion of the learned counsel. I shall not ask you to determine 

 whether these scientific men, witnesses for the prosecution, are 

 worthy of the place they have occupied in the scientific world 

 for fifteen or twenty or more years; but I will remind you of 

 the fact that as one distinguished author has said, " books follow 

 thoughts, not thoughts books." You have had the book-makers 

 before you ; you have had the men before you who determine 

 scientific questions. You have had their opinion, to the effect 

 that after a consideration of all the authorities, and after a re- 

 view of the whole subject witli careful analysis and reason, such 

 as scientific men have learned to use, their opinion, vouched for 

 by their reputation, is that the lactometer is a sure and practi- 

 cal test of the adulteration of milk ~by water, when it is properly 

 tested and is accurate. Now they have said further that as a 

 practical test it is just as accurate as analysis. It is not necessary 

 for us to go to that point; I desire to make it plain. It must 

 be admitted on all sides that analysis can only tell you the 

 amount of water in the milk ; the lactometer tells you the same 

 thing. How can you tell from analysis whether water has been
