First geological map of Britain, 1815

First geological map of Britain, detail of the north east coast (figure 8). This map was published in 1815 by British geologist William Smith (1769-1839). It shows rock layers (strata) in England and Wales and part of Scotland (key at lower left). Smith's work as a canal surveyor allowed him to study geology. He discovered that geological strata could be reliably identified at different places on the basis of the fossils they contained. Smith also proposed the principle of superposition, that if a strata overlays another then it was laid down at a later time. He is considered the father of English geology.

Stratified squamous epithelium Featured Print

Stratified squamous epithelium

Stratified squamous epithelium. Light micrograph of a section through stratified squamous epithelium, showing the multiple layers, or strata, that function to resist abrasion of the surface. This is the epithelial pattern found within the epidermis of the skin, but in this image, the absence of a layer of keratin is typical of the oesophagus (gullet). Squamous cells on the surface are continuously lost by cell death and exfoliation, but are replaced by the proliferation of stem cells located at the base of the epithelium. New epithelial cells mature and slowly displace towards the surface. The connective tissue beneath the epithelium, the lamina propria, contains nerves and blood vessels.
