It is called Sheep-Laurel in North America, as it is supposed to be 

 very injurious to sheep. Several varieties of this plant with lighter 

 and darker flowers have been described. There are several other 

 species, all of them natives of North America. They are all remark- 

 able for the irritability of their stamens, and each of the stamens 

 has a little cavity formed for it ill the corolla, to serve as a pro- 

 tection to the anthers. 



They are handsome shrubs when in blossom, and are great 

 favourites in gardens and shrubberies. They grow best in a peat 

 Boil, or they may be planted in a very sandy loam or vegetable 

 mould. They may be propagated by layers or seeds. When the 

 seeds are used they should be sown early in the spring in flat pans 

 or pots filled with peat-earth, and very slightly covered over ; the 

 pots may be then set in a close frame, or in the front of a hothouse, 

 till the plants come up, when they may be transplanted to other 

 pots, which should stand in a close frame till they have struck root ; 

 they should then be hardened to the air by degrees.

 KAMMERERITE, a Mineral, consisting of a hydrous silicate o/ 

 alumina and magnesia which occurs crystallised and massive. The 

 common form of the crystal is a 6-sided prism. The cleavage is 

 perpendicular to the axis only. Cleavage plane.? have a pearly lustre. 

 Colour, that of some crystals, which, by daylight is so dark that their 

 red colour is scarcely perceptible, appears by candlelight quite red. 

 Massive variety, usually composed of fine lamina). The colours are 

 sometimes dark violet-blue, sometimes yellowish or greenish, or 

 greenish- white. Translucent on the edges, particularly after immersion 

 in water. Fracture compact, fine-graiued, becoming splintery or leafy 

 on the less compact varieties ; flexible. Dull, or of a greasy lustre, 

 often glistening. When scratched it gives a light peach-blossom red 

 or almost white streak. Hardness 2'0 to 2'5. Specific gravity 2'64.

KARPHOLITE, a Mineral which occurs in minute crystals and 

 in stellated silky fibres. It scratches fluor-spar, and is scratched by 

 felspar. Colour wax or straw-yellow. Lustre of the crystals vitreous ; 

 of the fibres silky. Specific gravity 2'93. 



Before the blow-pipe on charcoal it fuses into a dark glass, which 

 becomes darker in the interior flame. With borax it melts into a 

 transparent glass, which in the exterior flame has a manganese 

 colour, and in the interior becomes greenish. The following are

KARPHOSIDERITE, a Mineral consisting of a hydrous phosphate 

 of iron, which occurs in reniform masses. Its structure is granular, 

 compact. Fracture uneven. Hardness 4'0 to 4-5. Specific gravity 

 2'5. Colour pale and bright straw-yellow, and streak the same. 

 Lustre resinous. Feels greasy. Opaque. When heated in a tube 

 gives off water, and a vapour which reddens litmus paper. 



Before the blow-pipe, per se, it becomes black, and melts into a 

 globule which obeys the magnet ; with salt of phosphorus, it forms 

 a black xcoria. It is found at Labrador.

KKLLIAD./E, a family of minute Molliuca belonging to the 

 Lamellibranchiate Acejt/ta/a. Forbes and Hauley place this family 

 between Lucinidw and Ofdadida. The British KMiadfS embrace 

 the genera Mtrntacuta, Turtonia, Kellia, Lepton, and Galeonura. 

 i ACL-TA ; TUBTONIA ; LKPTO.V.] The genus Kellia has two 

 British representatives, A', nu/jorbicularit and K. nilida. They are 

 email but elegant bivalves, living jn the crevices of rocks, or on shells 

 or sea-weeds, spinning a byssua, or lying free. There are about 

 a dozen species known in different parts of the world. This genus, 

 from which the family takes its name, was named after Mr. O'Kelly 

 of Dublin.

KK'RODON (F. Cuvier), a genus of Rodtntia, bearing in some 



respects resemblance to that of Cavia, but differing both in the loco- 

 motive aud masticatory organs.

Teeth of Kerodon. F. Cuvier. 



The molars all resemble each other, aud are composed of two equal 

 parts, each of a triangular or rather cordiforui shape, united on the 

 external side of the tooth, and separated on its internal side. These 

 triangles, or ' hearts,' are each surrounded by their enamel and filled 

 with bony matter, and their separation produces au angular notch 

 partly filled with cortical substance. 



When F. Cuvier wrote but one species, K. Moco, was known, and 

 this was discovered by Prince Maximilian of Neuwied, and noticed by 

 him under the name of C'ai'ia rupestris. The fur is ash-gray mixed 

 with reddish-yellow, blackish above and whitish below. Size, smaller 

 than that of the Guinea-Pig. 



This species was found in the rocky places of the interior of Brazi!, 

 near Rio San Francisco. 



In 1836 Mr. Bennett exhibited to a meeting of the Zoological 

 Society of London a Rodent sent home among the animals collected 

 by Captain Phillip Parker King, R.N., during his survey of the 

 Strait of Magalhaens, and presented by him to the Society, which 

 Mr. Bennett regarded as a second species of Kerodon, and for which 

 he proposed the name of K. Kingii. It was chiefly distinguishable 

 from that discovered by Prince Maximilian by its more uniform 

 colour. Excepting a slight dash of white behiud the ear, and a longer 

 line of the same colour marking the edge of each branch of the lower 

 jaw, the animal is entirely gray ; the upper surface being distinguished 

 from the under by a greater depth of tint, and by the intermixture of 

 a free sri/zling of yellow aud black. The crowns of the molar teeth, 

 as in the typical species, consist of boue surrounded by two triangles 

 of enamel, the bases of which are connected by a short line of enamel 

 passing from one to the other, all the lines being slender and sharply 

 defined. 



This species was found at Port Desire, on the eastern coast of 

 Patagonia. ('Zool. Proc.,' 1835.) 



Mr. Waterhouse refers the genus Kerodon to Cavia. [HYSTRIOID^;.] 



KEROLITE, a Mineral, consisting of a hydrous silicate of alumina 

 and magnesia, which occurs massive and reniform. Structure lamellar 

 or compact. Colour white, yellow, or green ; streak white. Fracture 

 conchoidal. Harduess 2'0 to 2'25. Lustre vitreous or resinous. 

 Transparent, translucent. Specific gravity 2-0 to 2'2. Feels greasy, 

 but does not adhere to the tongue. It ia found at Frankenstein in 

 Silesia, and at Zoblitz in Saxony, and also in New York and New 

 Jersey, United States. The following is au analysis by Pfaff :
