Sxa,-The following are the results of analyses of two samples of milk made by myaelf and by Profesaor Redwood. My own analyses wese made upon the milk in its fresh condition, and Professor Redwood examined the milks after they had been kept in bottles for 1s days. As the m i l k s were collected in the same town, namely, Aldemhot, and on the same day, I have no doubt, seeing that their compobitiou is praotically identical, that they are from the sitme dairy, although purchased of different vendors.

SIR,-I herewith send you a newspaper clipping shewing you the very unexpeoted results of om of our late trials in a suburban distlict of this city. In the central municipal, and all other district courts, however, conviction has followed each prosecution.Chief Justice Pemerton, of the central court, has upheld my proposed standard for cider vinegar, which you published in your reprint of my vinegar report, in your June, 1883, number-an acidity equivalent to the presence of not less than 6 per cent. by weight of acetio acid, and a fixed residue of not less than 1-5 per cent., at 212 degrees F., as this will allow of an average watering of 20 per cent. of the straight whole cider vinegar, as I have found it ; this surely is not drawing the lino too high. I hope a near number of your journal will con- taiu the explanation about the sp. gr. of thc Boston milk, which I asked Prof. J. F. Babcock, who made them, to send you. Yours sespectfully, B.F. DAVENPORT, Boston, Mass, Feb, 7th, 1884. State Analyst of Dimgs. [The following is the cutting referred to by OUY correspondent, and is taken from the Boston Jou~iial of Saturday, January 26th, 1884.--" GUILTY KNOWLEDW XUST BE PmvEx.-In the Somerville District Court, this morning, there was a healing before Judge Story, on a complaint charging Amos Haynes, of 4, Chatham Street, Boston, with selling vinegar which hail been adulterated with water. The case was brought in Somerville becausc the defendant's factory is situated there, and the particular sale upon which the case sestcd was made in that place. The adulteration was shown by the evidence of experts, but the defendant was discharged, the Judge stating that in all such cases he would require guilty knowledge to be proven. Dr. B. F. Dwenport, Inspcctor of Vinegar, strttcs that the Isw undcr which thcsc prosecutions are made docs not rcqnire such proof, and that under such a i*uling uo conviction call cvcr be ~ccurcd,"-Eu., TXIE AXALYST,
