In recent years, many of the collections present in the Museum have been submitted to study and to conservative restoration. Among these are the substantial nucleus of botanical findings, consisting of 14
mostly 19th-century, and of several
eaturing woods of varying origins, as well as a fine series of zoological samples consisting of more than 250
conserved in liquid and prepared at the Stazione Zoologica Anton Dohrn of Naples, all coming from the Gulf of Naples, in addition to several unusual collections of manufactures of various types that have valuable artistic and scientific interest, mostly realised between the end of the 18th century and the end of the following century. Particularly outstanding among these works are the collection of 118
of marine invertebrates produced by Leopold and Rudolf Blaschka of Dresden and the numerous productions from the ceroplastics laboratory that originated at the end of the 18th century at the Imperial Royal Museum of Physics and Natural History of Florence, the workplace of artists such as Luigi Calamai (a precious collection of more than 250 wax mushrooms)
and Egisto Tortori (the author of various anatomical models and more than 60
of naturalistic subjects).
