OR:

The Wardian case was an early type of terrarium, a sealed protective container for plants. It found great use in the 19th century in protecting foreign plants imported to Europe from overseas, the great majority of which had previously died from exposure during long sea journeys, frustrating the many scientific and amateur botanists of the time. The Wardian case was the direct forerunner of the modern terrarium and

. It is named after Nathaniel Bagshaw Ward (1791–1868) of London, who promoted the case after experiments. He published a book titled ''On the Growth of Plants in Closely Glazed Cases'' in 1842. A Scottish botanist named A. A. Maconochie had created a similar terrarium almost a decade earlier, but his failure to publish meant that Ward received credit as the sole inventor.

had germinated and were growing in a bit of soil. Interested but not yet seeing the opportunities, he left the seal intact for about four years, noting that the grass actually bloomed once. After that time however, the seal had become rusted, and the plants soon died from the bad air. Understanding the possibilities, he had a carpenter build him a closely fitted glazed wooden case and found that ferns grown in it thrived. Ward published his experiment and followed it up with a book in 1842, ''On the Growth of Plants in Closely Glazed Cases''. English

With the new Wardian cases, tender young plants could be set on deck to benefit from daylight and the condensed moisture within the case that kept them watered, but protected from salt spray. The first test of the glazed cases was made in July 1833, when Ward shipped two specially constructed glazed cases filled with British ferns and grasses all the way to
