This article gives a complete account on the animal reactions, and experiments carried out on Trypanosoma dimorphon found in cattle near Beira. The effect of passing the trypanosome through rats, transmission through flies, and the action of certain chemical agents on the trypanome in vivo are...

Having given a brief resume of his reasons for believing Anaplasma to be a distinct species of parasite, the author proceeds to describe experiments in support of this view.

Trypanosoma cazalboui is the most widely spread animal trypanosome in the West African French Colonies. Together with T. dimorphon it renders whole tracts of country uninhabitable for equines and bovines. T. pecaudi is to be found along the banks of all the rivers where they are wooded. Whereas T....

Experiment 1. A healthy kid was kept beside an infected goat in the open from the 15th September till the 1st October. The ears and the flanks of both animals were clipped in order to facilitate biting of the flies. The kid did not become infected.
Experiment 2. Sixty Stomoxys (S. calcitrans, ...

Reference is first made to a previous publication by the author in which he stated that he had examined 227 dogs in Palermo for Leishmania with negative results. In the present investi-gation the parasite was found in two dogs. In the first instance the infected dog was found in a house near to one ...

Dogs have been found liable to Kala Azar in practically all the great centres of the infantile form of the disease-Tunis, Algeria, Lisbon, Malta, Sicily, Rome, and Greece. It has been suggested by NICOLLE that the dog, in which the disease is mild and chronic, may act as a reservoir for the virus,...

While there is no record of the occurrence of rabies in the human subject in the French colonies in West Africa, there would appear to be a disease of the dog the symptoms of which are strongly suggestive of rabies. It also appears to be certain that the bite of such dogs is fatal to other dogs,...
