["Diary of health of every estate" and children's issues].

L. Lafontaine's "Diary of Health for Every Estate" including children's issues was being published from 1801 to 1802. It was the first Polish magazine addressed to the whole society. In its author's opinion this magazine was to propagate rules of hygiene, sanitary education and inform about methods of proceeding in different cases. Lafontaine devoted a lot of attention to sickness affecting mostly the poor and uneducated. He was the first to mention the problem of sick children. In articles, he refer to naturalism and Locke's and Rousseau's ideas. He mentioned and described defects, symptoms and children's illnesses from birth till adult. He talked over rules of physical behaviour and indispensable remedies for treatment in home. He was the man of merit in trying standardization of medical onomastics creating basis to develop independent paediatrics science.
