in which are found mainly norepinephrine-containing nerve endings and axons is due to a change in some regulatory mechanism acting upon the uptake process. This effect seems to be specific for norepinephrine; we have not been able to detect it with H3-serotonin under similar experimental conditions (8).

Teeth of 12 cremated paleo-Indians (11,000 years old) from caves in southern Chile have crown and root morphology like that of recent American Indians and north Asians, but unlike that of Europeans. This finding supports the view that American Indians originated in northeast Asia. This dental series also suggests that paleo-Indians could easily have been ancestral to most living Indians, that very little dental evolution has occurred, and that the founding paleo-Indian population was small, genetically homogeneous, and arrived late in the Pleistocene.

A large sample of Gallinazo cobs from Huaca Prieta is classified using a set of five variables. Some types of Gallinazo maize recovered there seem to have been new to the Peruvian North Coast; some types of the preceding Salinar phase are not known from this site. Further changes occur in the Chicama-Viru area when Moche influence appears. In several ways Gallinazo maize seems more related to maize occurring today further north and east than to modern highland or coastal maize to the southeast.

In proposing a pre-projectile point cultural stage for North and South America, Alex Krieger has cited certain lithic material from Taltal and other Chilean sites as supporting evidence. That this is an erroneous assumption can be shown by available data. As far as the Chilean record is concerned, Krieger and others have been misled by the low level of technology of certain specific artifacts for which false claims have been made. They have not recognized that these items are a very widespread feature of seemingly unrelated cultures ranging from the Peruvian and Chilean preceramic to the Inca of the 16th century.
