Noon. Has vomited some watery matter, with undigested potatoes in it, and again a rice-watery fluid with flocculi. He has now a considerable degree of jactitation; countenance more sunk, and great desire for cold water. These symptoms went on increasing in severity in spite of sinapisms to spine, effervescing draughts, calomel, and Dover’s powder, warm water, enemeta, &c., and head symptoms were now making their appearance. Half-past two P. M. Pulse quite imperceptible, and has been so for an hour and a half; he lies quiet and drowsy, with eyes turned upwards; face bedewed with cold perspiration; hands and feet cold and very blue. My colleagues, Drs. Combe and Lewins, saw him with me at this time, and concurred with me in thinking him not only beyond all hope of recovery, but likely to die _within an hour or two_. From what I had seen of the resuscitating powers of Dr. Latta’s treatment on the boy’s mother this morning, by venous injection, I determined on giving it a trial, though this was a case rather likely to bring discredit on the remedy than otherwise. The following solution, at temperature 102° F. was slowly injected into the median basilic by means of a common silver blow-pipe attached to Reid’s enema syringe:-- ℞. Muriat sodæ, ℨi; Carbon sodæ, gr. x; Aq. calid. ℔vj. solve. T. 102. Three P. M. A few minutes after the injection was commenced the pulse returned to the wrists, the blueness and coldness of the extremities gradually wore off; the countenance was much improved; and the whole fluid was injected within twenty minutes. Half-past three P. M. He has now a healthy, blooming appearance; is sitting up in bed, and looking about him as if awoke out of a dream. Pulse 110, natural; extremities of good colour and warm; voice much stronger. Half-past four P. M. Pulse has been gradually falling off since last report; is getting listless, and dislikes to be troubled with questions, breathing becoming laborious, and head symptoms more marked, with squinting to a slight degree superadded. Seven P. M. Pulse again imperceptible; respiration quick and laboured; countenance collapsed; tongue and breath cold; says he is dying. Let the venous injection be repeated to ℔iij. Half-past seven P. M. Pulse immediately returned, of natural strength and fulness, and continues so. Nine P. M. Lies very quiet; pulse good; breathing more natural; surface of body covered with warm perspiration. Ten P. M. Large watery evacuations from the bowels came on soon after last injection; the quantity cannot easily be guessed, but must have been considerable, as it is running through the mattress on the floor. Pulse scarcely perceptible; screams loudly like a child in hydrocephalus.
