allowed a little air to enter injection-tube, and tlience into jugu¬ 
lar, causing no inconvenience other than increasing heart’s 
action from 8o to lOO beats per minute. Stood stilly during 
operation, but in ten minutes laid down in great pain, shivered 
and broke out in sweat; breathing labored, heart lOO and 
strong. Large quantity brown fluid escaped from uterus when 
la}^ down. Urine continuous for half an hour. Got up and ate 
bran-mash. Continued to urinate and perspire till next day, and 
in two days all symptoms of toxsemia had disappeared. The 
solution used was made of one teaspoonful of sodium chloride to 
quart boiled water. That used in Massachusetts General Hos¬ 
pital is highly recommended : o.i gramme (grs. jss) CaCl, 0.75 
gramme (gr. x) KCl, to 1000 c.c. (qts. ij) normal saline solution. 
The apparatus was ordinary household fountain syringe, and 
required amount rubber tubing. End of tube fitted to ordinar\^ 
horse canula. Vein opened with lance after being raised, and 
while still raised canula is inserted. Care must be taken that 
no air is in tube before injecting. Everything thoroughly 
scalded before using. The infusion of saline fluid is indicated 
in following conditions : Serious haemorrhage from any cause 
or haemorrhagic collapse ; septicaemia or uraemia in all infectious 
diseases in which there is a well-marked toxic condition of 
blood, tetanus, ■ azoturia, strychnine poisoning, etc. Has been 
used with good results in acute pneumonia in man. In all 
forms of grave poisoning it is surely indicated. When infusion 
is used for relief of toxic condition of blood should be immedi¬ 
ately preceded by venesection.— {Jour. Comp. Med. and Vet.

This operation always considered diflicult and unsatisfactory 
because cutting out of cartilages must be done at 4 to 6 
inches distant from external wound, the wound being almost 
filled by operator’s hands, speculum and instruments. Being 
unable to see, the knife ma}^ slip or curved-scissors’ points

portions of the mucous membranes with the cartilages, and 
the tissues injured. When the cartilages are enucleated the 
effort to take up the mucous membrane properly with catgut 
suture becomes almost impossible, on account of the inability 
to see because of the small aperture and the frequent accumu¬
