(Gasterosteus pungitius.) All these fish had their bellies extremely 
swollen by the presence of a single Botriocephalus of the above-men- 
tioned species, and it only required to squeeze them a little, to make ths 
worm issue by the anus, or by a rent which took place in the abdomen. 
The Botriocephalus solidus can live several hours, and even two days, 
out of the animal, in water. 
On the pretended Venomous Bugs of Miana, (Argas Persicus, 
FiscHER.) Extracted from a Letter of Mr. J. Szovits, dated 
Khoi, June 1828.—Journal of St. Petersburgh, Sept. 1828.

Russian government to explore the Caucasus, that the pretended bugs 
of Miana, whose bite is so much dreaded at that place, and in other coun-

Some Account of an Ascent and Barometrical Measurement of 
Wha-ra-rai, a Mountain in the Island of Owhyhee. By Arcur- 
BALD MeEnziks, Esq. F.L.S.—Mag. of Nat. Hist. Vol. II. No. 
IX. p. 436. : 
Mr. Menzies passed two days on the top of the Wha-ra-rai, where he ga- 
thered the Sophora tetraptera, the Dodoneza viscosa, and a small-shrub- 
by geranium. The barometer stood, on the top of the mountain, the 
first day at 22 in. 40 pts. and the second day at 22 in. 44 pts. The mean 
of these two observations, deduced from 30 in. 16 pts., the mean of two 
corresponding observations on board the ship in Karakooa Bay, will 
render its height 8457 feet above the level of the sea. The thermometer 
was, at the same time, 65° on the first, and 64° on the second day.
