neath the incision, being vertical and six or seven centimetres 
long. The costal piece was thus exposed, pulled outwards as 
much as possible and resected 16 centimetres below the frac¬ 
ture. The lower end of the rib which remained fixed to the 
sternal cartilage, resumed its normal position. Cicatrization 
went on without complication.—( Archiv . Veterin. Nctoiik and

Hepatic Trematods of Birds [By A. Ratltiet].—Con¬ 
trary to what may be believed, the biliary tracts of birds have 
yet been very incompletely explored to the point of view of re¬ 
searches for parasites. Mr.' Railliet has made a certain num¬ 
ber of observations which have allowed him to study various 
forms of trematods, partly new or little known. They are seven 
in number and are found in various species of crows, magpies, 
jays, blackbirds and sparrow hawks. A somewhat curious 
fact is that all the parasites belong to the gender Dicrowelium 
(Dij), such as recently defined by Hoys, while a good number 
of hepatic trematods of birds to this day belong to different 
ge n de rs.—( Soc. of Biol.) 
PlROPEASMA CANIS—INFECTIOUS JAUNDICE OF THE DOG 
[By A. Leblanc]. —The author has already announced that he 
has found hsematozoa in the blood of a dog affected with infec¬ 
tious jaundice. He offers four new observations, which lead us 
to believe that in all the cases of infectious jaundice of the dog 
these parasites are found, and that they play an important, if 
not an exclusive part in the pathogeny of this disease. These 
hsematozoa are very analogous to those discovered by Dr. Mar- 
chome in the dogs of Senegal. They are much bigger than those 
of cattle or sheep. They are rare in the plasma ; i, 2 or 3 may 
be found in the same globule ; they are spherical or ovoid, 
rarely pisiform ; sometimes they look like two ovoid masses 
united by a contracted part.— (Soc. of Biol.) 
Influence of the Physiouogicau Work of Tissues 
upon the Production of Dymph [By Prof G. Afoussee ].— 
Continuing his experiments on the lymphatic circulation and 
studying the influence of work upon it, the author seems to 
demonstrate : (1) that the physiological work of the cephalic 
regions increases enormously the lymphatic circulation ; (2) that 
the muscular actions seem to act principally upon the secreting 
influences.— (Soc. of Biol.)
