This interesting fair is clearly a survival from pre-Celtic days, but the interest in the place has unfortunately been much obscured by the alteration of the old name Tan to St. Anne's Hill on all modern maps.
It was a very common and well-known custom of the Church in late times to alter the name of a place to that of a saint, where, finding large gatherings assembled for religious ceremonies, their object

Carbon Dioxide in the Breath. The presence of 0.06 per cent. of carbon dioxide in the atmosphere is held, I believe, to render the air unfit for breathing purposes, whereas 0.03 per cent. may be taken as normal. A consideration of the quantity of this gas which must be continually present in the lungs makes such sensitiveness on their part to appear rather extraordinary.
Taking an average expiration as 300 c.c. and the reserve "air" in the lungs as 2000 c.c., and assuming that the atmasphere contains 0.03 per cent. of carbon dioxide and expired air 4 per cent. of carbon dioxide, we have the following figures (a homogeneous mixture in the lungs is imaginrd for simplicity) :Jou refore Just after Just after spiration expiration inspiration
