J 5 8 . ^ I left It on March 8, at the 18. of the Horn of Aries, ab 
moft in the fame latitude 5 and I am apt to believe it will be 
Eehpied , which I wlfh I may be able to obferve this evening 
if if be not already palled. 
If Signior Caff mi hath obferved it on thole daies that 1 
have, he will be glad to find the conformity of our Obferva- 
tions. I fhall only add, that on C cbvuaTy q. we were furpri- 
zed 3 to fee the Comet again much brighter then ordinary,, 
and with a confiderable Train. Some did believe, that it ap! 
preach'd again to m But having beheld it with a Telefcope , 
! foon faid a that it was joyned with two final! Stars, whereof 
one was pretty bright, which I had already feen 3 on Fc~ 
hrttmy 2b» and 2p j And this conjunction gave the Comet 
that brlghtoefs, as it happens to mod of the Starrs of the 
fifth and fixt-h magnitude , where 2 or 3. or more are con- 
joyned, which perhaps would (hew but faintly fingle, though 
by.reafon of their proximity to one another , they appear 
but one fta-rr. Hence k was 3 that I allured my friends here , 
that the following days we fhould no more fee it fo bright, 
becaufe I knew, that there were none fuch fmall bright Stars 
in the way, which by mv former observations I conjectured it 
was to move.

An Obfervation imparted fo the Noble Mr . Boyle , by 
Mr . David Thomas, touching fome particulars fur- 
ther confiderable in the Monfter mentioned in the 
first Papers of thefe Pliilofophical Transactions. 
Upon the ftriCteft inquiry, I find by one, that faw the Mon- 
Urotis Calf and ftone 3 wi thin four hours after it was cut out of 
the Cows belly , that the Bread: of the Calf was not flony ( as 
I wrote ) but that the skin of the Break and between the Legs 
and of the Neck (which parts lay on the fmaller end of the 
ftone ) was very much thicker, then on any other part, and 
that the Feet of the Calf were fo parted as to be like the Claws 
of a Dog, The .(lone I have fince feen , it is bigger at one end 
then
