juices are more aqueous, are fpoiled bv a 

 little frort. The tcod of all tiiis race (of 

 fnaiis and flugs) is tender leavts, and 

 young fprcu:3 o: plants, which they de- 

 vour by meansof a to:>th-l ke bdy, grow- 

 ing in iheir upper jiw, with which they 

 rather fcrspe the leavrs to pieces tlian ma- 

 cerate them } for there i» no fign of any 

 teeth in their lower jaw. 



•' Thebetter todifcover the degree of li''e 

 in thefr creatures, the circulation of whofe 

 juices feems flow enough to come nearer 

 to a (lite of (fagmtion than the motion of 

 juices in other animnls, I hive endeavour- 

 ed to find out the (ituation of the heart, 

 and lo compnre its motion with the beats 

 of a ptndu'uin. The fiift fubjeft 1 met 

 with, wh.ch gave me the view of this part, 

 was a fniill f'a'l, jull hatched, whole bo- 

 .dy and fhell were Co tranCpaient, that I 

 Could difcover its beats to be diliant about 

 three fcconds ; but as I fuppofed the 

 juices in th's were much more fluid than 

 in the older fnaiis, I had recourfe to foir.e 

 of the largell I could find j but their 

 fhe'.ls not being tranlparert, I was obliged 

 to take them off as well as I could, with- 

 out wounding the fnaiis ; and then, on 

 <heir left fides, I plainly difcovered the 

 Jbeais of the heart to be about five fccc'iids 

 (diftant from one another, and three hours 

 ^fterwaids about fcven feconds, though 

 fome of them were ftrong enough to begin 

 the renewing of their iLcil, which they ef- 

 fcil by throwing out a great quantity of 

 vjfcous matter through the pores of that 

 part of the body which had been incafed 

 tefore. The motion of thefe creatures is 

 performed by repeated vindulations of 

 their flefhy parts, without the help of feet. 

 This undulating motion prelTes a vifcous 

 /natter out ot their pores, which ferves to 

 fallen them to any thing they crawl upon, 

 and helps them in creeping up the fides of 

 ^alls or trees, and even when they reverie 

 their bodies, and creep upon ceilings, 

 ■with their fhells downwards. But it is 

 obfeivable, that a fnail feidom puts itfelf 

 ii!0 motion except when it is in (earth of 

 food, or is about generating, and then 

 only when the ground is moiil, and it has 

 opportunity of fupplying its loft juices 

 by fre(h facd. 1 have remarked, that 

 when a fnail is obliged to pafs over a dry 

 dudy place, it lofes fo much of its vif- 

 cous juice, that it can hudly recovtr it 

 again." — BradUy^s Pbitofipbical Acccttnt

An Accov NT of an earthquake that 

 took place in the KIKGDOM of NAPLE9 

 en the 26TH of JULY, attJ of the 



ERUPTION of MOUNT VESUVIUS ort 



the iiTH of AUGUST ; feleiied chiefly 

 from PARTICULARS tranfmitted by 



MR. FALCONNET, a MERCHANT of 

 NAPLES. 



" A LTHOUGH I expreffed to you 

 JL\. by a former letter my regret thai 

 no eruption of Mount Vefuvius took 

 place, but that on the contrary the little 

 columns that arofe now and then were lefs 

 fince the earthquake, and how defirable it 

 was that a vent (hould be given by aft 

 eruption to the inflammable matter that 

 feenied to exill in the bowels of the earth, 

 I did not expe£l to hive this day to an- 

 nounce to you that my wifhes were ac- 

 compliflicd lad night by an abuiklant 

 eruption of lava from Mount Veluvius, 

 which, thcxigh we have not felt any frefn 

 fhock of an earthquake fince July 26, yet 

 row relieves us from any farther appre- 

 licnfion of new fhocks. 



" In the courfe of yederday, till abouf- 

 fcven o'clock in the jvening, Vefuviug 

 Vfa« Very quiet, emitting but little fmoke ; 

 it then increaled, with flames at intervals ; 

 at nine o'clock they became frequent j and 

 I obCerved when they fell, that the moutU 

 of Vefuvius appeared ftill as a furnace. I 

 was then on the terrace cf my country- 

 houfe at bt. Jeriv, weft from Veluviu«, 

 and very near it. Mrs. Falconnet had 

 juft left me to fit down to fupper in the 

 dining-room ; the fcene before me kept 

 me fome minutes longer. I then joii^ed 

 her, but had not fat down a minute whea 

 we were told the eruption was beginning. 

 In an inrtant we were on the terrace, and 

 obferved its having overflowed on tbs 

 fame fide as laft year, and rudied down 

 with fucli rapidity as to run more than a 

 mile in ten minutes, and in averyflioi: 

 time it reached the valley towards Tone 

 del Greco. Tiiii llream 0/ lava was im- 

 menfe, and extended with amazing rapi- 

 dity over the country. It divided itlelf 

 into three bianches, one of which, beyond 

 the Torre del Greco, furrcunded th« 

 Country, houl'e of the Cardinal Archbilhop 

 of Naples, and before morning it reached 

 the fea, and continued running into it.— 

 The llream of lava is much diminifhed j 

 but when it broke out, from about ten 

 •'clock in the evening till twdve, it wa*
