ROYAL AGRICULTURAL SOCIETY

OF ENGLAND.

At the monthly Council Meeting on December 7, Mr. H. Dent Brocklehurst reported the Committee's desire to place on record their appreciation of the services of Mr. J. L. Luddington who for the last fourteen years had been their Chairman. Throughout this period Mr. Luddington had. evinced much interest in the work of the Chemical Department and had represented the Society on the Lawes Agricultural Trust, and taken his part in the framing of the Fertilisers and Feeding Stuffs Act and in other enquiries of a chemical nature. Mr. Luddington's tenure of the chairmanship of the Chemical Committee had been marked by unvarying courtesy and consideration, and his colleagues much regretted the termination of his service as their chairman.

The list of samples analysed for members by the Consulting Chemist during the month of November had been submitted to the Committee. The annual report of the Consulting Chemist had been considered by the Committee, and, subject to slight amendment, passed for publication in the next volume of the Journal. The operation of the new Fertilisers and Feeding Stuffs Act had been postponed until July 1, 1928.

The report of the Consulting Chemist to the Chemical Committee was as under :

1.-Compound Cake Differing from Published Statement of Composition.

The agent of a large estate in Northants sent me for analysis a sample of "pig cubes," which was stated to be composed of 30 per cent. barley meal, 30 per cent. maize meal, 32 per cent. middlings, 5 per cent. whale meal, and 3 per cent. treacle. analysing the sample I found it to differ very materially from the statement given, alike in respect of the constituent materials and the analytical composition.

On

Thus I found the sample to contain cottonseed, oats, linseed, rice and rape, none of which were mentioned by the seller, while the respective analyses, as shown below, were essentially dissimilar.

Analysis of sample sent: Oil, 5.68 per cent.; albuminoids, 19 per cent.; carbohydrates, 43.43 per cent.; woody fibre, 10.58 per cent.; mineral matter, 7.71 per

cent.

Analysis (approximate) which sample, as guaranteed, would give: Oil. 3.7 per cent.; albuminoids, 14.4 per cent.; carbohydrates, 60.7 per cent.; woody fibre, 3.5 per cent.; mineral matter, 2.7 per cent,

It seemed that the purchaser had asked a local merchant to get a food made up for him composed of certain ingredients, and this was the result.

2.-Condimental Foods.

In "Occasional Notes," June, 1927, and in other reports, attention has been drawn to certain condimental foods sold at prices out of all proportion to their real value. These prices range from £40 to £58 a ton. But, in addition to this, complaint has been made to me by members of a practice that has grown up in connection with the foisting on purchasers of a delivery of the food much in excess of what was ordered. It would seem that two commercial travellers go round together and induce farmers to take some of the food by way of a trial. The latter may agree to this by ordering

cwt. (cost, in one case now before me, 29s.); they are then asked to sign a contract form which, without their being aware of it, commits them to the purchase of ton, which quantity is sent them, together with a demand note, much as follows:-"To 10 cwt. meal, £29 10s. Price, 59s. per cwt. Guarantee Oil, 10 per cent.; albuminoids, 15 per cent."

If the purchaser refuses to pay, he is summoned, and the signed contract is produced. Numerous cases of this kind have been tried, notably at Derby County Court.

Up to recently, and although strong endeavours have been made by County Councils and the National Farmers' Union to "show up" the methods pursued and the exorbitant prices charged, the manufacturers have, by production of the form of contract referred to above, been able to enforce payment.

It is to be hoped that purchasers will be careful as to the form of contract they sign. 3.-Ground Lime of Inferior Quality. A sample sent me from Hertfordshire gave :

Oxide of iron and alumina

Lime

6.43

67.59

16.73

[blocks in formation]

Silica

100.00

This was a well-burnt lime, and also finely ground, but it was made from inferior stone, having over 16 per cent. of silica, with somewhat much iron, etc. The consequence was that instead of having, as a good lime should have, 80 to 85 per cent. of lime, this had only 67 per cent., and at

The reduction of aromatic nitro compounds to the corresponding amino compounds with iron and hydrochloric acid is performed with a concentration of acid substantially greater than 6 per cent., or where there is used, instead of hydrochloric acid, an acid-reacting aqueous solution of a salt of an aromatic amine, it may be of the amine to be produced, this solution is of corresponding concentration. The process results in the production of a finely divided iron oxide suitable for use as a pigment. An example is given in which nitrobenzene is reduced with iron and hydrochloric acid so

that there is produced an iron oxide which, after being freed from salts and dried, may be converted into a pigment by ignition and oxidation. Reference is made also to the use of aniline hydrochloride instead of hydrochloric acid.
