on reducing the temperature to about 676° C. (the salt being 
apparently in a red hot semi-pasty condition), the flow of the current 
was almost stopped, the R. of the salt was then about 154,830 ohms. 
With a temperature somewhat below the last named, the salt 
entirely ceased to conduct. 
As all the experiments in this memoir were conducted under 
similar conditions, the comparative results are interesting, and afford 
a further indication of the generally non-conducting character of 
these salts of the halogen group, below their fusing points (KC1 fusing 
point 734° C., KI fusing point 634° C., KBr fusing point 699° C.), 
the reverse being the case with the other salts and glass employed. 
The author has not made any observations on the fluorides. 
5. Notice of a Second Specimen of Sowerby’s Whale ( Meso - 
plodon bidens), from Shetland. By Professor W. Turner, 
M.B., LL.D, F.R.S. 
The Shetland seas are frequented by several species of Ziphioid 
whales. Since the year 1870 I have come into possession of, and 
placed in the Anatomical Museum of the University of Edinburgh, 
the skull of Ziphius cavirostris * the skull and a large part of the 
skeleton of Hyperoodon rostratus , and the skull and almost complete 
skeleton of Mesoplodon bidens. f They were all captured on the 
north-east side of the mainland of Shetland. 
On the 2nd June of this year I was told by one of my students, 
Mr Charles Anderson, that a small whale had been taken a few 
days previously at Voxter Yoe, Pelting. This voe is about 13 
miles from Urafirth Voe, where in April 1881 the specimen of Meso- 
plodon bidens , above referred to, had been captured by his brother, 
Mr Thomas Anderson of Hillswick. Mr Charles Anderson informed 
me that, from the description which his brother had written to him 
of the Voxter Voe specimen, it was also, he believed, a Sowerby’s 
whale. I telegraphed, therefore, to Mr Thomas Inkster of Brae, 
near Voxter Voe, to secure the animal for me as little injured as
