    On subsequent rupture of the cyst, a microscopic examination of the con- tained larva revealed the ordinary characters of the Cysticercus which pro- duces the Tcpnia mediocanellata. Speaking generally, it may be said that the connective tissue and cellular aponeuroses were very feebly invaded; but in certain situa- tions, such as those occupied by the linea semicircularis and fascia lum- baris, several vesicles were closely associated; moreover, as regards the muscles themselves, extensive parasitic invasion was prevalent only in the more superficial layers. It was likewise noticed, as obtains in the parallel case of Trichina, that the larvae were disposed in the longitudinal direction of the muscular fibres, being at the same time more numerously grouped towards the points of osseous insertion or of aponeurotic attachment. Not a few large vesicles had inflamed and suppurated, the cysts being occupied internally by a thick green-coloured deposit. Referring to the left side only, we noted that all the breast-muscles (pectorahs major, p. transversus, and p. anticus) were much infested, but scarcely so fully as the more superficial panniculus carnosus. In the latissimus dorsi and trapezius the cysts were very numerous, rather less so in the combined levator humeri and sterno-occipitalis, somewhat fewer in the rhomboideus brevis and rhomboideus longus, and exceedingly scanty in the superior part of the scalenus, the remainder of this last-named muscle being entirely free. The lateralis sterni contained none ; neither were any observed in the abdominal region of the serratus magnus, but several vesicles were lodged in the superficial cervical portion of this muscle. Not a few existed in the upper part of the complexus major and in the complexus minor, some also occurring in the longissimus dorsi; yet none were observed in the spinalis dorsi, in the superficialis costalis, or in the diaphragm. Turning towards the neck-region, we found them abundant in the sterno-maxillaris, considerably less so in the splenius, only one in the hyoideus, several in the sterno-hyo-thyroideus, but none in the longus colli. All the other deep-seated muscles of this region, including the obliquus capitis superior and inferior, as well as the rectus capitis posticus major and minor, appeared free from any trace of the vesicles. On the other hand, all the superficial muscles of the face, such as the retractor anguli oris, orbicularis oris, and levator palpebrarum, gave abundant evi- dence of their presence, the vesicles being particularly numerous at the outer part of the masseter externus. In like manner their presence was only less strongly indicated in the muscles of the eyeball, such as the obliquus inferior, adductor and retractor oculi, also in the depressor oculi one measle being placed between the tendon of this last-named muscle and the sclerotic coat. The ball of the eye itself contained no vesicles. A few were remarked in the substance of the genio-hyoideus and other muscles supplying the tongue ; but the lingual organ properly so called appeared to be entirely free.
