THE ANALYST. 119 NOTES OF THE MONTH. The unintentional skimming of milk (first brought forward as a good defence in cases where a milkman was charged with selling skimmed for fresh milk, an the occasion of a certain learned professor's now historical ride in a milk cart) has again cropped up in Bath; and in an elaborate report, Mr. Gatehouse has concluded that, under oertain circumstances, such involuntary fraud is quite possible.In the face of this defence, it is certain that no prosecution for skimming milk can ever lie, but, in the interests of the public, we would suggest that when it is next offered, the prosecution should argue that an essential point in the business of a purveyor of milk is to use such vessels and such precautions as will secure that his final customers shall not be robbed to the advantage of the first; and that, no matter whether it be done wilfully, or only by want of due precaution, the offence of selling to the prejudice of the latter purchasers remains the same, and conviction should follow.Of course, if the magistrate is satisfied that it was a, case not of criminal intent, but only of contributory negligence, then he can take that as a plea ad naise)icordiam in fixing the fine.A recent case in which a sample of milk was sent to Somerset House for analyk throws some light on the differences in the deductions which the Inland Revewe chemists have drawn from their analyses, slid those obtained by Public halysts. A sample of milk was analysed by a Public Analyst in April. In May the sample was sent to Somerset House, but previously to sending it the bottle was opened by the inspector, and a portion of its contents removed by him in the presence of two analysts, one of whom examined the portion removed.The .bottle waa then re-sealed by the inspector, and forwarded the same day to the Inland Revenue Laboratory. The results obtained were as follows- First Analyst.Seoond Analyst. Somerset House, Solidsaot fat .. .. 7.78 7.58 7-14 Fat .. .. .. 2.50 9-43 2.38 Ash .. .. *87 -86 Not determined.

The interest of the analyses lays mainly in the fact that the second analyst and the Somemet House chemists reoeived the sample within a few hours of each other. It was then a month old, and the Werenoe between the first and second columns shows the change it had then undergone, but the Somerset House chemists find, either on the aame day or the next, 844 lesrr solidB sot fat thm No.2 analyst; OF 8s nearly 88 may CL i n ~ s h " .. .. -23 a a a ditto.120 THE ANALYST. be the same difference as exists between their stand&rd results and the results of Public Analysts generally.This points to the source of the discrepancy : their solids not fat are evidently dried at too high a temperature, or too long. We have pleasure in drawing the attention of our readers to the abstract which we print of the discussion which took place before the Institute of Chemistry on the subject of Food Adulteration, and we write this none the less sincerely, although we note with regret that but little new matter was brought forward by the various speakers.Indeed, the most striking feature in the whole discussion seems to have been, in the first instance, an attempt to ignore all the work which had been done by the Society of Public Analysts, although it amounted to as many thousands of analyses as the number of speakers present could claim to have made hundreds.After a short time, however, it became evident that the work of Public Analysts must be referred to, notwithstanding this attempt to ignore it, and we certainly have nothing to complain of in the criticism which it received, Coming from such a quarter, the criticism was sure to be severe, but that seems to us immaterial, for na statement put forward by the Society as a definite fact appears to have been in any way disproved. It would have been much better if the discussion had been an open one, so that a little new information might have been thrown on the subject.Apropos of this discussion, it is a very singular thing that the Presideut of the Institute should appear to think that Public Analysts, as such, are the gentlemen who are under-bidding, and therefore lowering the status of the profession.Practically, this is not so. We do not know of a single instance in which a Public Analyst does not get remuneration-say, for instance, for milk analyses-which is not above that accepted by some persons-it may be even by members of the Institute itself-for analyses of samples from private customers. True, the 2s. 6d.fee is named in the Act, but this fee is meant to be, and practically is in every case, supplemented by a respectable yearly salary. Could not the Institute take this subject up and look carefully into it ? Some of its influential members would be able to give important and valuable information on this point, even though they fairly and honestly admit their lack of experience in reference to food analysis.Is this the case always in reference to private work ?
