in Illyria. It contains 1440 square miles, with 176,000 in¬ 
habitants, and is divided into the four arrondissements of 
Trieste, Duins, Capo d’lstria, and Rovigno. 
TRIESTE, a large and thriving sea-port of the Austrian 
dominions, the capital of a district in the Illyrian territory. 
It is situated near the north-west extremity of the gulph of 
Venice, and is divided into the old and new town. It is al¬ 
most the only sea-port for a very large track of country, the 
south of Germany, the Illyrian provinces, and part of the 
Sclavonian; in short, for the long track of Austrian territory 
extending from Tyrol to Transylvania. The territory belong¬ 
ing to the town comprises 170 square miles, and a population 
of nearly 9000. Trieste belonged to France during five 
years, from 1809 to 1814; 212 miles south-south-west of 
Vienna, and 69 east-north-east of Venice. Lat. 40. 43. N.

TRIESTE ISLAND, a small island at the bottom of the 
gulf of Campeachy, westward of Port Royal Island, about 3 
leagues from east to west. The creek which separates it from 
Port Royal Island is scarcely broad enough to admit a canoe. 
Good fresh water will be got by digging 5 or 6 feet deep in 
the salt sand: at a less depth it is brackish and salt, and at a 
greater depth than 6 feet it is salt again. 
TRIESTY, mountains of Ireland, in the county of Mayo; 
21 miles west of Killala. 
TRIETE'RICAL, adj. [trietericus , Latin.] Triennial; 
kept every third year.—The trieterical sports, I mean the 
orgia, that is the mysteries of Bacchus. Gregory. 
TRIETERIS [Tpje7r/pK, Gr.], a cycle of three years. 
Thales, it is said, observing that the lunar revolution never 
exceeded thirty days, appointed twelve months of thirty 
days each; so that the year consisted of three hundred and 
sixty days: and in order to reduce these months to an agree¬ 
ment with the revolution of the sun, he intercalated thirty 
days at the end of every two years, whence that space of 
time was called a period of three, because the intercalation 
was not made till after the expiration of full two years, 
though really it was only a period of two years; as we are 
informed by Censorinus, De Die Natali. 
TRIE WALD (Martin), an eminent mathematician and 
engineer, was born at Stockholm, in 1691, and being in¬ 
tended for trade, he travelled to England for information and 
improvement on subjects that concerned his commercial pur¬ 
suits. Disappointed in prospects of this kind, he changed 
his object; and was fortunately engaged by the proprietor of 
some coal-mines, near Newcastle, to superintend the machi¬ 
nery of his works. This situation corresponded to his 
genius and inclination; and he was thus led to pay particu¬ 
lar attention to mechanics, both in theory and practice. In 
1726 he returned, after an absence of ten years, to his native 
Country, where he constructed a steam-engine, and read lec¬ 
tures in philosophy, illustrated by a course of experiments, 
similar to those of Desaguliers, which he had attended in 
London. He thus attracted the notice of the king and of 
the States, who conferred upon him a pension, with the title 
of Director of Machinery. He also proposed some improve¬ 
ments in the manufacture of iron and steel. Thus diligently 
and actively employed for the benefit of his country, he re¬ 
ceived a commission as captain of engineers and inspector of 
fortifications; and he invented various machines connected 
with those offices, models of which are preserved in the 
Academy of Sciences at Stockholm, and also in the Aca¬ 
demy of Lund. Diving was also an object of his attention, 
and on this subject he wrote a treatise, entitled “ Konst at 
lefwa under Watnet, or the Art of living under Water,” 
Stockholm, 1741, 4to. For this invention he received ho¬ 
norary rewards both from his own sovereign and the king of 
France. In 1729 he was elected a member of the Society of 
Upsal; and the same honour was conferred upon him by 
the Royal Society of London and other learned bodies. 
Triewald died suddenly in 1747. He communicated various 
papers to the Academy of Sciences at Stockholm, which 
appear in its Memoirs for the years 1739, 1740, and 1747.
