It has asingle spiracle. The. full-grown 
have twenty-two subconoid sharp teeth, 
a little hooked. Among those stranded 
in Scabay Bay were many young ones, 
which, as well as the oldest, wanted 
teeth. The youngest measured about 
five feet in length, and were stili suck- 
lings. The females,had two teats, larger 
than those of a cow, out of which the 
milk flowed when they were squeezed. 
These animals are gregarious, and follow 
one as their leader, They frequently 
enter the bays around the Orkney coast 
in quest of small fish, which seem to be 
their food. When one of them takes 
the ground, the rest surround and en- 
deavour to assist their stranded compa- 
nion: from this circumstance several of 
them are generally taken at once. They 
are inoflensive and rather timid, and 
may frequently be chased on shore by a 
few yawls. They are extremely fat and 
yield a considerable quantity of good oil. 
This new species Dr. Traill proposes to 
denominate delphinus melas. 
Mr. Acton of Ipswich, having used a 
still containing 9 gallons, for distilling 
common water, essential oils and water 
refigerated them with a tub which 
holds about 86 gallons, found it very in- 
convenient to change the water of the 
tub as often as it became hot, which it 
very soon did, after commencing distil- 
lation ; he therefore contrived the follow- 
ing addition to the refrigerating part of 
the apparatus, which he has found to suc- 
ceed so well, that he can now distil for 
any length of time withowt heating the 
water in the worm-tub above one devree, 
so thatit never requires to be changed ; 
the heat passes off entirely into the ad- 
ditional condenser, and when it exceeds

150 degrees, goes off by evaporation.. 
The additional condénser consists of a, 
trough three feet long, twelve inches 
deep, and fifteen inches wide, with a 
pewter pipe passing through the middle 
of it horizontally, about two inches in 
diameter, at the largest end next the stil} 
and gradually tapering to about three 
quarters of an inch at the smallest end 
which communicates with the top of the 
worm. The great simplicity of this con- 
trivance and its utility render a fair trial 
of it invother stills very advisable; the 
small degree of heat which went to the 
Water in the worm-tub shews, that the 
additional condenser performed nearly 
the whole of the condensation, and that 
therefore it is extremely probable, thata 
second pipe and trough added to the first, 
would perform the whole condensation 
effectually, without using any worm, and 
thus enable distillers to dispense with 
this expensive and troublesome part of 
the apparatus. 
The first volume of a new Analysis of 
Chronology by Dr. Hates, is expected 
to appear this month. The work.will
