The purpose of this paper is to direct attention to the possibilites of sodium fluoride as an insecticide. Recent investigations of this salt as a stomach poison, which I have undertaken with cutworms and locusts, as well as its few but successful previously known uses as an insecticide against fowl-lice, Mallophaga on mammals, cockroaches, and earwings, indicates that sodium fluoride may, in a number of cases, replace the use of arsenical poisons. During the past decade the use of arsencial insecticides has increased rapidly. We are at present threatened with higher prices and possibly with a shortage of arsenic, a situation accentuated by the present cotton-boll weevil programme of the United States of America, which involves the use of tremendous quantities of arsenicals. Any cheap stomach poison effective against insects and promising as a substitute for arsenicals should therefore be of considerable interest to the entomologist and to the farmer, especially if it carries the additional advantage of being considerably less poisonous to man, stock and birds. Sodium fluoride meets these requirements.

The Law

The past session of Parliament has witnessed the passing of an Act for the regulation of Life Assurance Companies in the United Kingdom, which, while introducing great changes in the law, still stops very far short of the system of legislation which has been for several years in operation in a few of the United States of America, and which is warmly approved of and urgently recommended for adoption by some persons in this country. The present may therefore be considered a fitting time for reviewing what has been done and considering whether any further legislation is desirable, and if any, of what nature it should be.

The Past

In the past few years many papers have appeared both in Europe and the United States of America demonstrating the value of Chlorpromazine and Reserpine in the treatment of mental illness. In the United States of America Kinross-Wright (1954) has reported on Chlorpromazine in the treatment of schizophrenia and claimed very satisfactory results; in this country Lomas (1955) and his collaborators have in several papers confirmed these results. With regard to Reserpine in the United States of America Kline (1954) has used the drug extensively with good results; in Europe, hopeful reports by Foote (1955) and McGrath et al. (1956) confirmed the value of this drug in psychiatric practice.

The Subject

This chapter introduces the subject of the book and summarizes its basic argument and structure. It explains that the United States of America has been the world’s leading state for the past seven decades, but that great power rivalry has returned in recent years with Russia and China becoming more assertive on the international stage. Indeed, many believe the days of U.S. global leadership are coming to an end in the face of challenges from its leading autocratic rivals. In contrast, this chapter argues that democracies have systematic advantages in international politics and that there is good reason to believe that the American era of international preeminence will endure.

The article examines the representation of nostalgic memory of the lost homeland, Lithuania, in the Lithuanian diaspora writer’s, Alė Rūta’s (1915-2011), trilogy called “The Destiny of the Exiled”, which consists of the novels Pirmieji svetur (1984; Eng. - The First Abroad), Daigynas (1987; Eng. – The Seedling Plot), and Skamba tolumoj (1997; Eng. Echoes from Afar). These novels describe the multilayered problems of Lithuanian immigration into the U.S.A. and life of the immigrants there. Alė Rūta (Elena Nakaitė-Arbienė) is a well-known Lithuanian author, most of whose works (novels and collections of short stories and poems, all written in the Lithuanian language) have been published by the publishers of Lithuanian diaspora in the United States of America. The trauma of the loss of the native land results in the transmitted nostalgia in her novels. The author both mourns over the lost homeland and shares with the readers her grief over this loss and longing for seeing it again. In doing this, Alė Rūta echoes the nostalgic voices of many immigrants, who left their native country at different periods. The article also discusses the issue of preservation of ethnic identity, which is constructed on nostalgic and often melancholic memories of the past, and explores different types of nostalgia, which forms a core of Alė Rūta’s trilogy.

The 19Th Century

After an enormous spread in the United States of America during the 19th century homeopathy had almost completely vanished from the scene by the beginning of the 20th century. For the past two decades, however, it seems once again to experience a kind of renaissance. Major aspects of this development—in terms of medical and cultural history, sociology, politics, and economics—are illustrated on the basis of a general history of homeopathy in the United States. Using original sources, a first attempt is made to reconstruct the history of homeopathy in San Francisco which has some institutional peculiarities that make it unique within the whole country.
