There appears a very great difparity between the 
two letters from Mr. Winkler to Dr. Mortimer con- 
cerning thefe fads. In the firff we are informed, 
that the effluvia from ball'am of Peru were not only 
perceptible in the perfon eledrifed, and in the air of 
the room ; but that thefe were carried along with 
the current of electricity through the open air into 
another chamber : that his company did not chufe 
to bear the offenfive fmell of the brimflone tranfpiring 
through his glafs ; and that it even heated his own 
blood : that cinnamon alfo fent forth its odour in 
great abundance, perceptible to any one immedi- 
ately entering the chamber, and continuing there till 
next day. 
In the fecond letter you will perceive, that there 
is a great abatement of what we were promifed to 
exped from the firft : we are there told, that the 
glafs globes and tubes now fent, if they are eledrifed, 
tranfmit odours, not thofe diredly of the fubffances 
included, but fuch as are plainly different in fmell 
from the eledrical effluvia, and which, to ufe his 
own words, viri odoratu. valentes hie , Lipfia diji indie 
J'enferunt ; fo that muff we conclude, that our nofes 
are not fo good as thofe of the gentlemen at Leipfic ? 
Mr. Winkler does not even fay in his l^ft letter, that 
he can eledrife with the cinnamon-globe, and that * 
the vapours fent from it are to be fmelt at the en- 
trance of the chamber ; but that, with a great deal 
of management, they are to be perceived within 
an inch or two of the globe; which however we 
had the mortification not to be fenfible of with the 
greateft attention.
