observed. Continuous medullary pattern was exhibited<br />
both in pigmented and unpigmented ear hair of the female.<br />
Long tail hairs of male animals showed narrow continuous<br />
pattern and a narrow segmented pattern in the eyelid.<br />
Compound elongate pattern was seen on the hairs of the<br />
muzzle of male animal. No medulla was observed in other<br />
regions especially in the female. As shown in this study,<br />
the hairs from different regions examined had imbricate<br />
crenate cuticular pattern, however, more than one medullary<br />
patterns were observed in a given body region. The hairs<br />
of the male and female cannot be differentiated from one<br />
another because of the similarity in their morphology. The<br />
present study showed that scanning electron microscopic<br />
characterization of the hair cuticles, and light microscopic<br />
description of medullary patterns could be used in species<br />
identification. However, their application becomes limited<br />
in cases of absence cuticles due to traumatic injuries, and<br />
also when there is a thick and highly pigmented cortex. In<br />
such cases, cuticular and medullary findings should be<br />
supplemented with gross observations (size of hair, color<br />
of hair and cross section of medulla) and if available, DNA<br />
analysis.<br />

COMPARATIVE GROSS ANATOMY, HISTOLOGY<br />
AND HISTOCHEMISTRY OF <strong>THE</strong> TRACHEA OF <strong>THE</strong><br />
<strong>PHILIPPINE</strong> <strong>WATER</strong> <strong>BUFFALO</strong> (Bubalus bubalis) AND<br />
CATTLE (Bos taurus)*<br />
H. H. Telada, Student<br />
The gross anatomy, histology and some histochemistical<br />
properties of the bubaline and bovine trachea were studied.<br />
The trachea of the Philippine water buffalo (53.41 ± 4.73<br />
cm) was significantly longer than that of the cattle (47.63 ±<br />
4.93 cm) (P
