Guide to an Exhibition of 
sea, and had concreted into stone during the consolidation of 
the soil. 
Another Italian naturalist of note, Fabio Colonna [1567- 
No. 33. 1650], published in 1592 a Phytobasanos remarkable for the 
’ beauty of its illustrations. He extended Caesalpinus’ method of 
classification to the formation of genera, but did not draw up a 
system. In Geology he was the first to point out in his 
Osservaztoni sugli Animalt aquatili e terrestri that some fossils 
belonged to marine and others to terrestrial testacea. 
John Gerard [1545-1612], a celebrated English botanist, 
had a garden in Holborn, of which he published a Catalogue 
(the first to be made of any garden) in 1596 and again in 1599. 
L’Obel’s copy of the second edition is in this Museum, and 
contains his manuscript notes and denial of the attestation 
printed at the end stating that he had seen the plants growing in 
Gerard’s garden that are enumerated in the work. Gerard’s 
No. 31. great work, however, was the Herbal^ published in 1597, 
compiled chiefly from Dodoens after the method of L’Obel 
and illustrated by cuts mostly taken from a work of Theodorus 
Tabernaemontanus. He did much to advance the knowledge 
of Plants, while to him is due the discovery of many species 
then new to England. 
THE next serious attempt, after that of Gesner, to compile 
a universal natural history, or encyclopaedia, was made 
by Ulisse Aldrovandi [1522-1607], the Italian naturalist, 
who spent his patrimony over the compilation and production 
of his series of well-known volumes, which were issued at 
Bologna between 1599 and 1668. He has fortunately 
No. 34. preserved to us the accounts of Monsters, both mythical and 
actual, accepted up to his time. 
THE study of Mineralogy was not greatly advanced at this 
period, and the only work of any note is that by Anselm 
Boethius de Boodt [1550-1634], physician to the emperor 
No. 32. Rudolf IL, who published in 1609 a Gemmarum et Lapidum 
historiay which was long a work of practical value, although it 
was chiefly devoted to the minerals used as gems. In it he 
figures a lapidary’s wheel which is practically identical with a 
kind in use at the present day.
