And to deliver roore diftinftly the faccefsj you are to 
know 3 that in the firft immerfion of the Globe ^ as foon 
as it touched the Icy water, there was obferved in the wa- 
ter of the Glailes neck a fmail rifiog , but that fufficieiitly 
quick 5 after whichj with a motion regular eoough^ and of 
middle velocity, it retired back to the Globe 5 till being 
cocoe to a certain mark, it continued not to defcend any 
further, butftopp'd there for a while, being altogether^ as 
far as v/e could fee, movelels. Afterwards, little by little 
k was feen to begin to rife again ^ but with a very flow 
motion, which was in appearance even and regular s from 
whence, without any proportioned acceleration^ it fuddedly 
and furioufly ftarted upwards 5 in which time it was im- 
poffible to follow it with our eyes, it running up with this 
impetuoufhefi, in an inftant, as 'twere, through feveral tens 
of the marked degrees. And as this violence began in a 
moment^ fo in a moment it ended ^ forafmuch as from this 
very great velocity it fuddenly pafled to another degree of 
motion 3 which though nimble enough ^ was yet incorapas 
rably leis than the precedent ^ and going on to rife in this 
degree 3 it went to the top of the next ^ and at laft run 
over. 
All the whilcj riiat thefe things happen'dj there were at 
times feen on the top of the water feme bubbles ^ either 
Aerealj or of another more fubtile marterj now in a grea- 
ter, then in a leflcr plenty : And this feparation did not 
begin till the water had begun to take a brilk cold 5 as if 
the force of fuch a cold had the power of ftraining fuch 
matter, and fevering it from the water. 
Now being deffrous to fee, whether thofe alterations kept 
among themfelves any kind of Analogy, we began to reite- 
rate the conglaciations, and no fooner was one Ice deflroyed, 
but we fet it to freeze anew : And the water went to con- 
gele again in the fame order of ^alterations 5 which yet 
did not every time return to theTelf fame points or de- 
grees in the neck.; Which made us heiievcj that they had
