Jn securing and preserving compositesamples of milk or cream, it will be well toobserve the following points: The milk orcream must be thoroughly mixed by pour-ing from one pail or can to another severaltimes to evenly mix the butter fat with themilk serum. A small dipper (Fig. 1) maybe used to farther agitate the milk. Thisdipper should have a solid metal * handlefor convenience in cleaning and the capacity should beabout one ounce, or just large enough for measuring thedesired sample
