The Zoological Journal was a scientific periodical published between 1825 and 1835 in England. The men associated with its creation included Thomas Bell, John George Children, James De Carle Sowerby, George Brettingham Sowerby, and Nicholas Aylward Vigors.
James De Carle Sowerby, son of the legendary botanical illustrator James Sowerby, demonstrated his own exceptional skill in the plates. The journal was published by his brother George.
Thomas Bell's famous Monograph of the Testudinata (1832-36) was illustrated in part by James Sowerby the younger, but due to problems with production, some of Sowerby's plates were omitted, and didn't appear until 1872's Tortoises, terrapins, and turtles drawn from life. However, a few managed to find their way into publication early, in the Journal, engraved at a reduced size in copperplate as reverse images.
The plates below are a sampling from the full set contained in the five issues of The Zoological Journal and supplements. They are 300 dpi files, reduced from 600 dpi scans. File size averages at around 3mb.
