Coloured Engraving of a dodo

Engraving of a dodo, an extinct, flightless bird, related to the pigeon. The size of a swan, it was heavily-built and clumsy. Two species were known with certainty: the common dodo Raphus cucullatus from Mauritius, which became extinct between 1665 and 1670, and the Rodriguez solitaire Pezophaps solitaria from the neighbouring island of Rodriguez, which died out around 1761. The dodo's numbers quickly dwindled following the arrival of humans to these isolated habitats. All but defenceless, they were ill-equipped to cope with the new hunters & the competition from other introduced species. Copper engraving from Historia Naturalis Brasiliae, W. Piso & G. Marcgrave, 1658

Optical fibres

Optical fibres. Bundle of optical fibres conducting light. These fibres are made of very pure glass which is coated so as to allow light to be transmitted without absorption or loss of intensity. This allows data such as telephone conversations, television pictures and computer transmissions to be sent in large volumes without a loss of quality
