One acarus, in fact, does not abandon a groove once made — 
nothing induces it to decamp : every thing conspires to make us 
believe that it dies upon the spot after having travelled about 
l-25th part of an inch during the twenty-four hours, and pierced 
the epidermis covering it with small apertures through which 
the young larvae hatched along the train of its eggs may make 
their escape. 
The transmission of a single acarus suffices in man to produce 
itch. The animals we have submitted to experiment have all 
received a greater or less number of insects without expe- 
riencing the slightest indication of the disease. 
Let us, therefore, conclude that the communication of itch (or 
mange) from man to animals, and from animals to man, is im- 
possible, though the diseases of the skin in animals often prove 
the occasion of some affection of the same organ in man.

At the Annual Examinations for honours, held at the above 
institution at the close of the past session, the following were 
the questions propounded by the respective teachers ; and to 
which the names of the successful competitors are added. 
It is extremely gratifying to record the progress which is 
being made in the education of the student of veterinary me- 
dicine, who is much advantaged by acts like these, from a healthy 
and laudable stimulus being by them imparted to his mind, the 
benefits resulting from which do not cease with his pupillage. 
Session 1850-51. 
1. Name the Cranial Nerves; their numerical arrangement, 
and their endowments separately. Also state the foramina 
through which they obtain exit from the cranial cavity. 
2. Describe the changes which the Food undergoes in its pas- 
sage through the alimentary canal of the horse, commencing with 
the lips ; and point out the most striking peculiarities in the 
process of assimilation, as performed in the horse, comparatively 
with ruminating and carnivorous animals. 
3. State the number of Teeth in the mouth of the foal at birth, 
and say to what class they belong; also state if any other of the 
same class are subsequently developed; and if so, at what periods; 
and further explain the nature of the changes generally, which
