    viruses are the smallest living particles, and are impossible to discern with an ordinary microscope though they can be photo- graphed by means of the electron microscope. They are responsible for many cosmopolitan diseases, some grave and others trivial. Many viruses have been studied by serological techniques which enable them to be distinguished and identified. No classification of the pathogenic viruses has yet furnished un- equivocal grounds for grouping virus diseases according to the relationships of their causal agents. The sequence followed in the Museum is therefore based upon somewhat ad hoc collections of disorders bearing similar clinical or epidemiological patterns. Introduction to viruses 6 panels Classification of i panel Arthropod-borne viruses These viruses are placed at the beginning. They are among the smallest, and are of tropical importance Yellow fever 6 panels Sandfly fever 2 panels Dengue fever 3 panels Epidemic encephalitides 2 panels ■ Encephalitis lethargica i panel Other encephalitides of viral i panel origin Rabies 3 panels Poliomyelitis 4 panels Zoster i panel Arthropod-borne virus infections Virus infections of the central nervous system This condition links the neurotropic viruses with those of the pox group
