mon courfe I had obferved in Animals, not far from the date* at 
which it would begin to ftiine : and having cat out a piece of it, 1 
caufed the reft to be hung up again in a Cellar, and the exfe$ed 
piece to be pur into a {mall and cran {parent Receiver, that we 
might obferve, if a day or two, or more, after the Fifh in the 
Cellar fhould begin to ftiine, that in the exhaufted Receiver would 
either alfo ftiine, or (becaufe that feemed not likely) would, not- 
withftanding the check, which the abfence of the Air might 
be prefumed to give the Putrefaction, be found to ftiine too, 
.either immediately upon the admiffion of the Air, or not long 
after it. 
.Sue this Experiment, as I lately intimated, was only defigned 
and attempted, p t compleated 5 the Receiver being fo thin, that 
upon the exhauftionofthe internal Air, the weight of the external 
broke it $ and we could ill {pare another of chit kind from Trials, 
we were more concerned to nuke: Notwithstanding which we 
made one Trial more, which fucceded no better than the former, 
but mifearried upon a quire differing account, a;/'*, becaufe nei- 
ther the included piece of Fifh, nor the remaining, though it were 
of the fame fort with the Fifties I ufuail employed, would Shine 
at all, though kept a pretty while beyond the ufual time, at which 
fuch Fifties were wont to grow luminous* 
If this Experiment had fucceeded, I had iome others to try in 
profecution of it, which I flull not now trouble you with the men- 
tion of. Sut that this Paragraff may not be ufelefs to you, Fie take 
this occifion to give you a Couple of Advertifements, that may 
relate not only to this Experiment, but alfo more generally to 
thofe, whether precedent or fubfequent, where Shining Fifh are 
employed.

I N thefixft. place then , I will not undertake , that all the Experi- 
ments you Jha/l make with rotten Fifh, fall have juflthe fame 
fuccefs with thefe I have related, for as I elf e where, obferve d (in a 
Difcotirfe written purpofely on that fuhje0that the "event of divers- 
other Experiments is not always certain, fol have had Qccafion to ob- 
ferve thdike about Shining of Fifties. And,befides what I lately took 
notice of at the clofe of the tenth Experiment, I remember ^ that having
