Purueent Conjunctivitis, due to the Absence of the 
Lachrymal Opening of the Left Nasal Duct \Kuehn \.— 
Towards the end of February, the author was called to attend 
to a case with a history, that since the last three months there 
is a profuse, yellowish, thin, purulent discharge from the left 
eye, and that the flow of the discharge can be increased by 
taking a hold of the horse’s chin and elevating its head in that 
manner. The examination revealed the correctness of the own¬ 
er’s statement, and the author found as cause of the stated ail¬ 
ment, the missing of the left lachrymal opening. At the place 
of the opening there was a slightly yellowish spot. The treat¬ 
ment consisted in the opening of the skin at this yellow spot 
corresponding to the diameter of the right lachrymal opening. 
After this was done a 35 cm. long, and 3 mm. thick hard rub¬ 
ber probe was inserted into the artificial opening, and in this 
procedure the natural nasal duct was reached. In inserting the 
probe, by a peculiar motion, at the depth of 10 cm. a slight 
obstruction was reached, which, in forcing through the probe, 
appeared to be thin bone plates. After overcoming this ob¬ 
struction it was an easy task to force the instrument into the 
lachrymal sack. Soon after the operation there emptied quite 
an amount of discharge of a yellowish, thin, purulent character 
from the nasal opening. To prevent the closure of the artificial 
opening and for the treatment of the purulent conjunctivitis a 
catheter specially made for this purpose was given to the owner, 
which could be attached to a balloon syringe, with the direc¬ 
tion to insert this several times daily into the nasal duct, in¬ 
jecting a 1 per cent, solution of sulphate of zinc. Complete 
recovery took place inside of 8 days.— (Berl. Thierctrzt. Woch-

Experimental Studies as to the Heredity of Tuber¬ 
culosis [D r . F. Friedmami \.—Ever since the nature of tuber¬ 
culosis was known, again and again the question is brought up 
as to whether it is possible to transmit the disease by the way 
of the placental circulation from the mother to the child, or if
