and belly, and in some parts into orange. A narrow white stripe 

 ascends from the tip of the nose to between the eyebrows. The 

 black ears described by M. Temminck are not alluded to by our 

 author. There are two large, thick, tactile hairs (gevoelsharen), 

 above the internal angles of the eyes, and two others at some distance 

 above the outer angles, besides some at the sides of the nose and on 

 the lower lip. At first view these hairs appear to differ in structure 

 from those of the pelt, yet they are possessed of the same elements. 



The following is Dr. Kingma's account of the microscopical ex- 

 amination of the hair. By a glass of moderate power, the hair is 

 seen to be clear and transparent at the root. At some distance, 

 transverse striae are seen, following one another regulai-ly. At 

 a greater distance from the root, these transverse striations are 

 more perceptible, and give the hair a jointed appearance, like that of 

 a tape-worm. These joints are so formed that the upper part of 

 each is somewhat broader than the lower part of the ensuing one. 

 By this regular succession of broader and narrower portions, the 

 edges of the hair acquire an undulated appearance. The wavings are 

 the strongest in the lowest third of the hair ; further towards the 

 point, they become merely perceptible. In each joint is a cavity, 

 shorter than the joint itself. The lowest portion of this cavity is 

 hollow and clearly diaphanous, whilst the upper part, defined by a 

 right line, is filled with a black pigment. These pigment-spots are 

 about 001 (0*001 ?) of a millimetre broad, and 0-005 mm. long. The 

 cavities are completely separated from one another. In the first 

 third of the hair, like the joints themselves, they are more developed 

 lengthwise, and the pigment is much darker ; further on, they ap- 

 pear more compressed from above downwards, and fit closer to one 

 another. At some distance from the tip of the hair, the cavities dis- 

 appear altogether, yet the articulations remain clearly perceptible 

 nearly to the point. 



The four hands are entirely devoid of hairs on their palmar surfaces. 

 The head is of an oval form, with a prominent snout, the lower jaw 

 receding behind this part at an oblique angle. Its most remarkable 

 appearance, however, arises fromthe spacious orbits ; they nearly 

 join each other above the nose, and by a slender projection of the 

 outer angle of the frontal bone, corresponding with a similar 

 construction of the malar bone, bulge out at the sides, so as to 

 render this ])art of the skull, when seen from below, wider than 

 any other. This is best seen in Dr. A. Smith's figure of the cranium 

 of the Galago Moholi, which he has given of double the natural 

 size. Near the large eyes rise up the still larger, thin, elongated, 

 external ears of the animal. In the hollow of the auricle there are 

 three or four grooves, divided by corresponding folds. The hind 

 limbs are longest and most developed. The palmar surface of the 

 hands is furnished with a number of callosities, that form elastic 

 cushions, upon which the animal alights in its noiseless bounds. 

 All these peculiarities of organization have a strict and intimate 

 bearing upon the functions and habits of the animal — upon its noc- 

 turnal and insectivorous characters.
