30 SWEDENBORG’S TRAVELS AND DIARIES. [Doc. 205 .
1728, and there I found a review of Michael Mercati’s Metallo
theca, where it is stated that Albertus Magnus [who died in
1280] , is the only one who in former centuries published any
methodical treatise upon minerals ; that he was followed by
Camillus Leonardi in the sixteenth century, and also by
Mathiole Fallopius, Valerius Cordo, and Agricola, of whom
the latter was most successful. Mercati studied with An
dreas Cæsalpinus, and died in 1593 ; his work, however, was
published after his death by Pope Clement XI ; 120 years
after the death of the author M. Lancisi added notes to it.
The contents of the book are as follows : 1. The earths ;
2. Salt and saltpetre ; 3. Alum ; 4. Acid and acrid juices,
vitriol, orpiment, and sandarach; 5. The bituminous juices ;
6. Marine plants ; 7. Stones which are similar to earths ;
8. The stone bezoar ; 9. Figured stones ; 10. Marble. The
author intended to prepare a second volume on the spars, the
precious stones, gold, silver, copper, &c.; but his death pre
vented its accomplishment.
The anatomist Bianchi has published several anatomical
disputations, in which he has explained the mechanism of the
human body. He is desirous of publishing in Turin two
volumes in folio, on all the parts of the human body and their
mechanism, with reference to their diseases and cures.
Jean Jerome Zannichelli has published in Venice a natural
history of the island which is contiguous to Venice. Last
year he published an excellent dissertation on iron and a
certain crystalline salt without taste which is extracted from
iron, and on the preparation of its snow [i. e. on the exsic
cation of that salt] . He mentions many particulars concerning
this metal incidentally.
July 11. I perused Peter Horrebow’s Clavis Astronomiæ
(The Key of Astronomy), published in Copenhagen in 1730,
where I found nothing to notice except some hypotheses of
no value ; he quotes, however, several experiments made by
others, which are worthy of notice, viz. 1. The celebrated
Teichmejer, the weather being very hot and the sky perfectly
serene, filled a glass cylinder with ice and common salt, the
same being quite dry on the outside, and exposed it to the
air. In the space of an hour he noticed that a crust of ice,
