428 M. de luc’s Barometrical Obfervations on 
come there in bad weather. In an inftant the ivory, of 
which this new inftrument as well as the former is con- 
ftrudted, was covered with ificles ; and what merits fome 
attention as to the matter of the humor , the hygrometer 
was by that means brought very nearly down to the 
point of extreme humidity. 
I ffiall not here detain you with accounts of feveral 
other obfervations made with this inftrument in the 
courfe of my journey. I am much better pleafed with it 
than with the firft, for many reafons ; however, I have 
not got over all the difficulties, but luckily alfo I have not 
exhaufted all the refources. 
I likewife obferved the Barometer on this eminence ; 
I had done it at fetting out from Oder-brucke, and did it 
again on my return. I had likewife correfponding obfer- 
vations at Claufthal,and during the whole of my journey 
I had 
mauvais terns. En un inftant Eyvoire, dont ce nouvel inftrument eft fait 
coniine le premier, fut couvert d’une couche de verglas; et ce qui merite quel- 
que attention dans la matiere de /’ humor , l’hygrometre fut reduit par la a tres 
peu pres au point de Phumidite extreme. 
Je ne m’arraterai pas ici fur quelques autres obfervations que j’ai faites avec 
cet inftrument pendant mon voyage* J’en ai ete plus content que du premier a 
divers egards. Cependantje ne fuis pas au bout des difficulties : mais heureufe- 
ment non plus, je ne fuis pas au bout des refources* 
Je fis auffi Pobfervation du barometre fur cette hauteur. Je l’avois faite en 
partant d’Oder-brucke, et je la fis au retour. J’avois auffi des obfervations cor- 
relpondantes a Claufthal : i’en eus pendant tout mon voyage de journailleres, a 
c Claufthaij
