form very poisonous compounds, and all lead-adulterated utensils should be wholly discarded for cooking purposes. _Test for Lead-Adulterated Tin._--Place upon the metal a small drop of nitric acid, spreading it to the size of a dime, dry with gentle heat, apply a drop of water, then add a small crystal of iodide of potash. If lead is present, a yellowish color will be seen very soon after the addition of the iodide. Lead glazing, which is frequently employed on crockery and ironware in the manufacture of cooking utensils, may also be detected in the same manner. Cooking utensils made of copper are not to be recommended from the point of healthfulness, although many cooks esteem them because copper is a better conductor of heat than iron or tin. The acids of many fruits combine with copper to form extremely poisonous substances. Fatty substances, as well as salt and sugar, act upon copper to a greater or less degree, also vegetables containing sulfur in their composition and produce harmful compounds. Utensils made of brass, which is a compound of copper and zinc, are not safe to use for cooking purposes. TABLE TOPICS. Bad cooking diminishes happiness and shortens life.--_Wisdom of Ages._ Says Mrs. Partington: "Many a fair home has been desiccated by poor cooking, and a man's table has been the rock on which his happiness has split." SIGNIFICANT FACT.--_Lady_--"Have you had much experience as a cook?" _Applicant_--"Oh, indeed I have. I was the cook of Mr. and Mrs. Peterby for three years." _L._--"Why did you leave them?" _A._--"I didn't leave them. They left me. They both died." _L._--"What of?" _A._--"Dyspepsia." Cooking is generally bad because people falling to routine; habit dulls their appreciation, and they do not think about what they are eating.--_Didsbury._ _Lilly_ (Secretary of the cooking class)--"Now girls, we've learned nine cakes, two kinds of angel food, and seven pies. What next?" _Susie_ (engaged)--"Dick's father says I must learn to bake bread." _Indignant chorus_--"Bread? How absurd! What are bakers for?" It is told of Philip Hecgnet, a French, physician who lived in the 17th, century, that when calling
