![of the middle with the lower third, or perhaps a little nearer the middle, a more or less clearly diiFerentiated oesophagus (?) became likewise discernible, and appeared to have a caecal termination; but beyond this, until the caudal extremity was reached, the continuation of the digestive tract was less clearly defined (Fig. Ill, 3.) It then became too dark to continue the observation, and by the next morning the Filaria had become uniformly mole- cular, all appearances suggestive of internal organs havino- vanished, although it still continued to coil itself languidly amongst the blood corpuscles. Such is the minute anatomy of the Hajinatozoon as far as I have been able to make it out. What has here been recorded has now been repeatedly observed, and may be observed by any one possessing a good or immersion lens and a microscope ])rovided with good arrangements for illumination. The simple detection, however, of the Hjema- tozoa, when present in the blood, is simply a question of patience, and not dependent on any special perfection in the magnifying powers employed. The average diameter of the Hasmatozoon, as usually found, is, as already stated, about that of a red-blood cor- j)uscle, and its average length about 46 times that of its greatest width ; that is to say, its greatest transverse diameter is about of an inch, and its length about V?th of an inch. These aie about the measurements most frequently met with, but I have occasionally seen specimens not more than half this size. The largest specimen which I have measured was found to be slightly over g^^^th of an inch in width, and about T^^th of an inch in length, whereas the smallest was Worth of an inch in width and ^^th of an inch in length: the relative proportion between the length and the greatest](https://iiif.wellcomecollection.org/image/b28709470_0035.jp2/full/800%2C/0/default.jpg)
