Slingrebøjler. Det kan meget vel oftere have hændt, at 
Vand er slynget ud af Fordunstningskarret, uden at saa- 
dant er blevet bemerket. 
Maaske vil man faa den bedste Bestemmelse af Hav- 
vandets Fordunstning ved Iagttagelser gjorte paa Land- 
stationer ude paa Kysterne. Her kunne Apparaterne, der 
vistnok bør være svømmende, staa i Ro. Vindhastigheden, 
der spiller en saadan overvejende Rolle, kunde registreres 
ved en Vindmaaler, der stod lige ved Apparatet, 1 samme 
Højde som dette. Og de øvrige Beregningselementer kunde 
ogsaa registreres 1 Nærheden.

paratus did not swing well in the gimbals. 
It is by no 
means improbable that water was frequently jerked out of 
the evaporating dish without our having noticed it. 
Possibly the best measurements of the evaporation of 
sea-water may be effected by observations taken at land- 
stations on the coast. There, the apparatus, which should 
unquestionably be kept floating, can remain at rest. The 
velocity of the wind, that plays so important a part in 
determining the results, could be registered with an anemo- 
meter, mounted in immediate proximity to the apparatus, 
and at the same height. The other elements of computa- 
tion might also be registered close by.
