The collection of Pre-Linnean works now contains more than 
250 volumes, and not only gives distinction to the library but has 
frequent practical value. Out of seventeen works of early botan- 
ists requested on one occasion for the use of a group of high 
school teachers who were making a study of the history of botany, 
the library possessed fourteen, half of them in contemporary 
editions. An illustrator for a publishing house came several times 
to study old herbals for antique style of plant drawing. On an- 
other occasion the herbals were used by a book collector who was 
interested in colored illustrations in the early days of book making. 
A specific case was the use of Mattioli’s Herbal of 1559 for con- 
temporary evidence on the dates of the founding at Padua and 
Pisa of the oldest existing botanic gardens.
