    I am fully convinced of the efficacy of Serocalcin and always have some in the house for my own family. My boy at a public school gets, or used to get, dreadful colds, ending up with bronchial catarrh and profuse sputum, and he always goes back to school armed with a box of tablets as a preventative. It also cures his cold, even if one has started. My colds are also formidable, usually (without tablets) lasting a fortnight or more and making me feel really ill, but if I start with nine tablets a day at the onset, the cold is gone in two days.

None of us had a cold until March—my son took a slight cold and this cleared up in two days by taking nine tablets of Serocalcin a day. This is by far the best record we have ever had. Neither my wife nor myself have been without a cold for more years than we can remember. Also, I should say that my daughter and one other girl took the preventive treatment and were the only two girls in their school who did not catch cold all winter long. I know of three other families who have had marked success with Serocalcin. You are free to use this letter for whatever purpose you think fit. Signed, R.H.

We appreciate this immunity, as colds are extremely annoying to men engaged in flying duties and sometimes cause serious complications, such as split eardrums and sinus trouble. Our supply of the tablets is exhausted and we wish to take another course of them before the winter sets in. Signed; . (0. JV RS ee I thank you very much for you letter and box of Serocalcin tablets, also copy of pamphlet. They are really wonderful tablets, and invaluable for children. Signed, (Mrs.) H.D. Although I have never written a testimonial to a manu- facturer of pharmaceutical products in my life, I feel, however, that I must, now that winter is well behind us and that the
