Dob-tailed cow?" The youth replies, "It is not necessary, 

 I have the black cow, sample number three. Get the other side 

 to taste it, and the case is done." I thought we would trace this 

 cow-relationship a little. I thought we would go one step more. 

 So I asked Mr. Charles Doremus, another member of the 

 family, more about this tribe of cows, which has been hitherto un- 

 known in science. There is 110 description of any such cows any- 

 where, except in the evidence of the professor's family. I could 

 read you books without number, but I will take the testimony 

 which you have heard. No such cows were ever known before, 

 therefore I wished to trace them. I said to Charles Doremus, 

 " This sample of milk is very like another we have had ? " He 

 was talking about the samples he had in the Kiieib case, and 

 about the " bob-tailed cow." " There is another rnilk, that of the 

 black cow, like this," I said. " Yes, it is," he said, " in whey." 

 " Is it like it, in other respects ? " " Yes, sir, in other respects." 

 There are no such cows to be found except in this " Doremus 

 tribe." The black cow and the bob-tailed cow stand together, 

 and when Prof. Doremus goes on to give you a standard of milk, 

 he begins with these. It is from these that he gets his low stand- 

 ard. I will read an extract from Wanklyn, and we shall see if 

 there is not a standard for milk. Wanklyn, page 41, says : " In 

 dealing with milk supply on a large scale, we are little concerned 

 with the possibility of single animals giving abnormal milk, and 

 need only concern ourselves with milk of normal quality, all de- 

 partures from the standard being looked upon as sophistications." 

 The fact is claimed by him that the normal standard of milk 

 varies, if I remember right, only two degrees. Now I take up a 

 book, "Du Lait," by Marchand, and read this: "Every time 

 that we shall meet a milk of which the corrected density shall 

 be inferior to 1.030 at a temperature of 15 [Centigrade], and 

 which shall contain less than 30 gr. of butter, 50 gr. of lactine, 

 we shall affirm with certainty and without fear, that the milk is 

 falsified." I read from the last edition of Tardieti, the edition 

 of 1862 : " In one word, the frauds indicated by the lactoden- 

 simeter are certain, but it is far from indicating all frauds." On 

 page 521, 1 read that " the lactodensimeter is a useful instrument
