transferred to the rude angle-instruments of the Arab navigators; and Prinsep deduces from statements
in Sidi Alis book that the isaba was very nearly equal to 96 and the zam to 12. Prinsep had also
found on enquiry among Arab mariners, that the term zam was still well known to nautical people as
1/5 of a geographical degree, or 12 nautical miles, quite confirmatory of the former calculation; it was
also stated to be still applied to terrestrial measurements (see J.A.S.B. v. 6423).

Un marin ma rapporté quil avait" fait la
traversée de Sérira (Sarbaza) à la Chine dans un Sambouq (see SAMBOOK). Nous avions parcouru, dit-
il, un espace de cinquante zâmâ, lorsquune tempête fondit sur notre embarcation.
Ayant fait de leau,
nous remîmes à la voile vers le Senf, suivant ses instructions, et nous y abordâmes sains et saufs, après un
voyage de quinze zâmâ.Ibid. pp. 19091.
1554.26th Voyage from Calicut to Kardafun (see GUARDAFUI).
you run from Calicut to Kolfaini (i.e. Kalpeni, one of the Laccadive Ids.) two zams in the direction of
W. by S., the 8 or 9 zams W.S.W. (this course is in the 9 degree channel through the Laccadives), then
you may rejoice as you have got clear of the islands of Fúl, from thence W. by N. and W.N.W. till the
pole is 4 inches and a quarter, and then true west to Kardafún.
27th Voyage, from Diú to Malacca.
Diú you go first S.S.E. till the pole is 5 inches, and side then towards the land, till the distance between it
and the ship is six zams; from thence you steer S.S.E.
you must not side all at once but by degrees,
first till the farkadain (b and g in the Little Bear) are made by a quarter less than 8 inches, from thence
to S.E. till the farkadain are 7 1/4 inches, from thence true east at a rate of 18 zams, then you have
passed Ceylon.The Mohit, in J.A.S.B. v. 465.
The meaning of this last routier is: Steer S.S.E. till you
are in 8° N. Lat. (lat. of Cape Comorin); make then a little more easting, but keep 72 miles between you
and the coast of Ceylon till you find the b and g of Ursa Minor have an altitude of only 12° 24 (i.e. till
you are in N. Lat. 6° or 5°), and then steer due east. When you have gone 216 miles you will be quite
clear of Ceylon.
1625.We cast anchor under the island of Kharg, which is distant from Cais, which
we left behind us, 24 giam. Giam is a measure used by the Arab and Persian pilots in the Persian
Gulf; and every giam is equal to 3 leagues; insomuch that from Cais to Kharg we had made 72 leagues.P.

JAMBOO, JUMBOO, s. The Rose-apple, Eugenia jambos, L. Jambosa vulgaris, Decand.; Skt. jambu,
Hind. jam, jambu, jamrul, &c. This is the use in Bengal, but there is great confusion in application,
both colloquially and in books. the name jambu is applied in some parts of India to the exotic guava
(q.v.), as well as to other species of Eugenia; including the jamun (see JAMOON), with which the rose-
apple is often confounded in books. They are very different fruits, though they have both been classed
by Linnaeus under the genus Eugenia (see further remarks under JAMOON). [Mr. Skeat notes that
the word is applied by the Malays both to the rose-apple and the guava, and Wilkinson (Dict. s.v.) notes
a large number of fruits to which the name jambu is applied.]
Garcia de Orta mentions the rose-apple
under the name Iambos, and says (1563) that it had been recently introduced into Goa from Malacca.
This may have been the Eugenia Malaccensis, L., which is stated in Forbes Watsons Catalogue of
nomenclature to be called in Bengal Malaka Jamrui, and in Tamil Malaka maram i.e. Malacca tree.
The Skt. name jambu is, in the Malay language, applied with distinguishing adjectives to all the species.
