THE DRY PURIFICATION OF COAL GAS 587 Analysis—Within ten days of cach delivery the seiler and buyer shall exchange results of their respective analyses of sample. Should these results diller in the percentage of ferric oxide by not more than 2 per cent, the mean. shall be taken, but if the difference exceeds 2 per cent, then a Temaining sealed portion of the sample shall be submitted to an independent analyst (nominated by the buyer and agreed to by the selier), whose decision shall be final. The cost of such analysis shall be borne by the party whose result is the more divergent. Forfeiture—Should the analysis of the sample of any delivery show that the conditions herein specified are not complied with, then it shall be at the option of the buyer to make such deductions from the account as shall compensate him for loss arising from the non-compliance. Failure of Delivery—In the event of any failure on the part of the seiler to deliver the material of stipulated quality and otherwise in accordance herewith, the buyer may procure a corresponding quantity of material from otter parties, and any loss incurred by the buyer in so doing is to be borne by the seller, and to be deducted from any sum due to him, or, in the event of no such sum being due, is to be recoverable by action as if on a simple contract debt. Payment—Payment shall be made within fourteen days of agreement as to analysis, less 2| per cent. Arbitration—Any dispute arising out of or in connection with this contract is to be settled by arbitration by two arbitrators (one to be named by each party) and an umpire, in manner provided by the Arbitration Act of 1889 or any statutory modification thereof. Sampling and Testing Spent Oxide The advance in the price of the sulphur unit in spent oxide, and, therefore, the greater accuracy necessary in both sampling and testing, has drawn attention to the want of standard methods acceptable to both buyers and seliers of spent oxide. Such standard methods exist for ascertaining the valne of other sulphur raw materials. The buyers of spent oxide have therefore drawn up the following standard methods for sampling and testing spent oxide. These methods have been submitted to and approved by the National Gas Council. Sampling—Samples sent for Quotation purposes are often assumed to represent bulk deliveries. This is almost impossible to be the case, as the bulk of the oxide may subsequently dry further or become damper owing to exposure. It is also possible that portions of the heap of oxide which contain more or less sulphur may have become covered up and not included in the sample, however carefuUy taken. The spent oxide should, therefore, for invoicing purposes, be again sampled during loading and the greatest care taken. to obtain correct proportions of lumps and fines, as these may contain different percentages of sulphur. When deliveries are being made, daily samples are to be taken from every cart or wagon and collected in an air-tight receptacle. It cannot be too strongly ernpha-sized that samples must not be allowed to lie about exposed to the risk of drying, but must be mixed, ground and bottled each day. When the delivery of the parcel
