Certainly no individual, nor the profession collectively, has, or can have, any right to com- plain, if for the future, the relation between the medical prac- titioners of this country and the insurance offices, be one of complaint, grudging, and insult.

THE

ANALYTICAL SANITARYCOMMISSION.

RECORDS OF THE RESULTS OF

MICROSCOPICAL AND CHEMICAL ANALYSESOF THE

SOLIDS AND FLUIDSCONSUMED BY ALL CLASSES OF THE PUBLIC.

CHICORY AND COFFEE,WITH THEIR

ADULTERATIONS.

IN previous Reports we quoted the observations made byDr. Pereira in reference to the employment of mineral in-gredients, as Venetian-red and reddle, for the purpose of height-ening the colour of the roasted and ground chicory-root.In corroboration of these remarks, we detected a red earthy

substance in two samples, the results of the examination ofwhich we have already made known.As, however, the use of such ingredients is of great import-

ance in a sanitary point of view, we have instituted specialanalyses, in order to determine the extent to which this kindof adulteration is carried.The evidence of the use of these substances, as we have

already seen to be the case with cocoa, is principally derivedfrom the incineration of a certain quantity of the chicory-powder. All vegetable substances, whether coloured or not,yield, on incineration, a greyish-white ash. The ash of colouredearthy substances, on the contrary, after being burned in acrucible, remains more or less coloured.

As, however, chicory is the root of a plant, and as the earthymatter is but seldom entirely removed from it by washing, theash of even genuine chicory not unfrequently exhibits, on thisaccount, a slight degree of coloration, being occasionallybrownish, or of light-fawn colour. It is only, therefore, whenthe ash is decidedly coloured, and especially when of a red orrusty-red colour, that the presence of Venetian-red, reddle, orsome other analogous substance, is rendered certain.

In these facts, therefore, we have a ready means of de-termining whether a sample of chicory, or any other vegetablepowder, contains an admixture of mineral ingredients-a con-clusion which may be confirmed by chemical experiment.In the following analyses we have not confined our atten-

tion to this one particular, but have made complete analyses ofthe whole of the samples under examination.

RESULTS OF THE MICROSCOPICAL AND CHEMICAL EXAMINA-TION OF SAMPLES OF CHICORY OBTAINED OF DIFFERENTMANUFACTURERS.

We refrain from publishing the names, except in theinstance of proprietary articles, of the manufacturers ofthe samples of chicory given below, as they were not pro-cured by ourselves direct from the manufacturers, but throughothers.

2nd. That several of the samples yielded a coloured ash.3rd. That out of the sixteen samples of chicory purchased at

the establishments of different grocers in the metropolis, oneonly was adulterated with roasted farina.

4th. That the ashes of several of the samples were coloured.5th. That out of the twenty samples of coffee submitted to

examination, nineteen were adulterated with chicory. Thegenuine coffee was purchased of illr. Valentine Smith, of 53,Aldersgate-street.

6th. That several of the samples, on incineration, left acoloured residue.

The next Report of the Analytical Sanitary Commissionwill be on

ISINGLASS,AND ITS ADULTERATIONS.

, With reference to a portion of the Sanitary Report that

appeared in THE LANCET of last week, the following advertise-ment was published by the League Company in the Times ofThursday. We do not hesitate to give it a place in ourcolumns. Notwithstanding this advertisement, we insist thatour report is accurate.

" LEAGUE BREAD COMPANY.-The Directors of the Company,having seen in THE LANCET journal, of the 25th of Oct. inst., astatement to the effect that alum was contained in three

samples of their bread, think it due to themselves, their share-holders, and to the public, unequivocally to declare that it isentirely untrue. Ever since the commencement of their un-dertaking, the Directors have faithfully carried out the prin-ciples on which it was founded-viz., the manufacture andsale of Pure Unadulterated Bread.’ As the only means im-mediately within their power of refuting the calumny thuscast upon the Company, they subjoin a copy of a declarationsigned by the whole of the men employed in the manufactureof the Company’s bread, which is as follows:-" League Bread Company.-We, the several persons whose

names are hereunto subscribed, being the whole of the work-men now and for the last twelve months at least employed bythe League Bread Company, in the manufacture of theirbread, do severally, solemnly, and’ sincerely declare, thathaving read a statement in THE LANCET journal, published onthe 25th October, 1851, to the effect that alum was containedin three samples of the Company’s bread, we know suchstatement to be utterly false and unfounded, and we furtherseverally declare that during the time we have been in theCompany’s service, no alum or other deleterious ingredientwhatever has ever been used or employed in the manufactureof the Company’s bread, and that it is impossible that thesame could be so used or employed without the fact beingknown to us.’"The three agents, of whom the bread is stated to have

been purchased, have also signed a declaration that they havenever sold any bread but what has been delivered to them bythe Company, and expressing their belief that the statementin question is untrue.

" Applications have been personally addressed to threeseveral police magistrates to allow the above declarations tobe judicially made by the parties who attended for the purpose,but the magistrates, and afterwards a judge at chambers,decided that they had no power to permit them to be made." Head Offices, 7, St. John.street, Clerkenwell, Oct. 29, 1851."

TRUE BENEVOLENCE.-The Times of Tuesday lastcontained an advertisement, in which the committee for pro-moting the subscription for D. B., of Bedford, gratefullyacknowledged the receipt of &pound; 100 from an anonymous donor.We rejoice to record this noble act of philanthropy towards amost deserving and unfortunate member of our profession.
