    or indirectly tlirough tlie person in ch.aro;e, tin's is still more useful.) A I'ecord of tlie sanitary condition of the premises must be made and the house inspected in detail as to the num- ber of persons occupying each portion of it, their occupation, and the work-place, or scliool attended. In the case of Small Pox the Vaccination Officer must be notified. If the infectious sufferer be a child notification should be sent to the teacher of the school attended by the patient. The principal points of these details, in addition to the particulars on the Notification, Certificate, should be kept consecutively in an Infectious Disease Kegistcr so that all essential references to any particular case may be seen at a glance. Sampling Water.—As another illustration it is frequently necessary in rural districts to ascertain the quality of the well water. For this purpose a sample of the water must be taken. The best method is to use a Winchester quart bottle, equal to a half gallon, with a ground glass stopper. The bottle should be well cleansed and prepared by being rinsed Avith hydrochloric or other acid, and then be rinsed several times with water until the drippings are no longer acid to the tongue and taste, and at the time of use, rinsed with the water to be sampled. The bottle should then be filled with the water within an inch, or so of the neck, the stopper inserted and tied down securely. Sometimes a luting of linseed meal or clean clay is laid round the stopper; but an india-rubber cap over all is the best. It should then be securely packed in straw or hay in a wicker basket for transport. Sampling Food.—Another instance, under the Sale of Food and Drugs Adulteration Act you must be familiar with the usual procedure. A sample is purchased in the ordinary way by yourself or by an agent. After paying for it, the vendor is informed for what object it has been purchased. Divide the sample into three parts; securely fasten and seal each part and number and letter them, taking note of the number and letter and of the name and address of the vendor. Offer one of the parts to the vendor, take the other two parts away, sending one to the analyst and retaining the other to be produced in court if a prosecution be necessary. For the purpose of sampling, ])roper bottles and tins with labels attached must be carried in a bag, which should also contain a special notebook. The quantities necessary to be purchased are about a pint of milk, or a pound of butter, and other substances in proportion, but an ounce or two of condiment is sufficient. In sampling milk or other food in transit it is necessary only to take the sample without dividing it: but, in case of prosecution it is necessary for the consignee to give evidence as to what he had contracted
