These and the former specimens were sent over in bottles of 
water. They were the same sealed bottles in which they were 
collected in the year 1842. In the first little bottle, in which 
the sediment was considerable, almost every atom being a distinct 
siliceous organism, Hemiaulus antarcticus predominated. The 
larger bottle of the second mass had allowed the greater part to
