Pulse”; of stationary or permanent pulses; observations made on 
the pulses of children before and after their having respired ; of the 
acceleration of the pulse after birth; observations on quadrupeds 
with respect to this; supposition that the foetus remains before 
birth in the state of the cold-blooded aninials; of the final cause of 
this peculiarity; of the cause of the stethoscopic sounds of the 
foetal heart being very rapid, although the pulse in the funis be slow ; 
an account of an experiment made by a watch ticking under water ; 
of the remarkable strength of the fcetal pulse as felt in the chord; 
of the absorption of the blood in the chord into the system of the 
foetus after delivery ; and the inference from this in favour of the 
views of Sir David Barry and Dr. Carson respecting the suction power 
of the thorax as influencing the circulation.

On the Use of Chloride of Soda in Fever. By Roz. J.Graves, M.D. 
Dr. Graves commenced a series of clinical experiments in 1832 
upon the efficacy of chloride of soda in petechial and maculated 
fever. He has exhibited this medium at Sir Patrick Dun’s Hospital 
and at the Meath Hospital, where its effects have been witnessed by 
a great number of physicians as well as pupils. The form recom- 
mended is Labarraque’s solution, which is a saturated solution of 
chloride of soda. ‘This was given in doses of from fifteen to twenty 
drops in an ounce of camphor mixture every fourth hour. In the 
commencement of fever, where there is great heat of skin and signs 
of vascular excitement, its employment is contraindicated. It is 
also inadmissible in cases where there is decided evidence of vis- 
ceral inflammation. When the early stage of fever is past, when all 
general and local indications have been fulfilled, when there is no 
complication with local disease, when the patient lies sunk and pro- 
strated, when restlessness, low delirium, and more or less derange- 
ment of sensibility is present, when the pulse is quick, when the 
body is covered with maculz or petechie, and the secretions from 
the skin and mucous membranes give evident proof of what has. 
been termed a putrescent state of the fluids, it is then that the chlo- 
ride of soda may be prescribed with advantage. It operates, although
