brown colour, peeling off in large deciduous flakes from the bases of the 

 principal branches and trunk, and none but the oldest portions are 

 cinereous. The racemes are fascicled and as long as the leaves." 



The gum is procured by making longitudinal incisions through the 

 bark in the months of May and December, when the cuticle glistens 

 with intumescence from the distended state of the parts beneath : the 

 operation is simple, and recpiires no skill on the part of the operator. 

 On its first appearance the gum comes forth as white as milk, and ac- 

 cording to its degree of fluidity, finds its way to the ground, or concretes 

 on the branch near the place from which it first issued, from whence it 

 is collected by men and boys, employed to look after the trees by the 

 different families who possess the land on which they grow. 



Dr. Carter's specimens were collected in 1846 at Rakhcote, a small 

 village close to Ras Sajar, on the South-east Coast of Arabia. 



The Boawellia glabra, Roxb., which inhabits Coromandel, yields the 

 fragrant resin Goondricum, or as it is called on the Malabar coast 

 Koonthrekum, the Googola of the Telingas. The Boswellia tliurifera, 

 Colebr., is also found in the same locality, and at Nagpore, but the 

 true Salai, which is the produce of this tree, is almost a curiosity in 

 India, for only a small fragment is contained in the Bombay Museum. 

 Olibanum, the produce of India, is therefore not an article of commerce. 

 Dr. Birdwood has carefully collected the vernacular names by which 

 Olibanum is known in India, Sallaci, Sillaci, Cunduruci, Amduri, 

 Surabhi, and Suvana, being the Sanscrit ; Salai, Sale, Sila, Sala, Sajuvan, 

 Gundaharosa, Dhoop, Esus, and Ltiban, Hindustani (Dlioop is also 

 applied to the resin of Cauarium striatum). In Guzerat, Olibanum is called 

 Koundur-zuchir, in the Deccan, Awul-goondur, and the Tamul synonym 

 is Paranghi-sambrani.

" Where shall we in future get our paper from ?" is at the present 

 time a stereotype question among paper-makers. And they have indeed 

 reason to ask the question, for it is a well known fact that the consump- 

 tion of paper is emimously increasing in all civilised States. The ex- 

 planation of this is not only the increased productive activity of litera- 

 ture in general, and the periodical press especially, but also the quicker 

 pulsation of public and private commercial life, caused by the freer
