mendes Wachsthum. Breslau, 1708/’ In this it is pointed 
out that the German language would be held in much 
higher estimation and more studied by foreigners if men of 
science would write in their own language, as it was now 
done in England. Every one wished to learn English since 
a Boyle, Hook, Spraat, Backon, Brown, Simson, Plot, 
Blunt, Gildrey, Sibhald, and many more ingenious men 
investigated and elucidated the innermost secrets of Nature 
in their own language. 
‘^On a Peculiar Feature in the Water of the Well in, 
Carisbrooke Castle, Isle of Weight,” by Harry Grimshaw, 
F.C.S. 
The sample of the above water was taken by me on April 
19th, 1878, but was never opened or interfered with in any 
way until the following September. The water when taken 
was very bright and clear and free from sediment of any 
description. It was totally devoid of odour and was of a 
fresh and sparkling taste. The local features of the well 
from which the water derives its origin are as follows : — 
Carisbrooke Castle stands on a small isolated chalk hill, 239 
feet above the level of the sea. The well is under cover in 
the “well house,” and according to Jenkinson is 240 feet in 
depth. It is perfectly free, even at the surface of the water, 
from carbonic acid gas, or in fact of more than traces of any

water burns freely. 
The bottle containing the water was opened on the 1 2th 
of September, and on doing so a very strong odour of 
sulphuretted hydrogen was perceived, and on testing with 
lead paper an equally strong reaction for that gas was 
obtained. There was also apparent a slight sediment of a 
white colour not originally seen in the water. The reaction 
to litmus was perfectly neutral. The analytical data
