GLUCOSE IN THE ANIMAL ORGANISM. 
ations of the nerves in the muscles, and does not affect the 
irritability of the heart and muscles at all, we may conclude, 
that a poison, which, as the Antiar, is capable of paralysing 
the muscles after the Urari, has really a direct action upon 
the muscular fibre. 
The results of my investigation into the effects of the 
Antiar upon frogs, are therefore the following : 
1. The Antiar is a paralysing poison. 
2. It acts in the first instance and with great rapidity (in 
5 to 10 minutes) upon the heart, and stops its action. 
3. The consequences of this paralysis of the heart are the 
cessation of the voluntary and reflex movements in the first 
and second hour after the introduction of the poison. 
4. The Antiar paralyses in the second place the voluntary 
muscles. 
5. In the third place it causes the loss of excitability of 
the great nervous trunks. 
6. The heart and muscles of frogs poisoned with Urari 
may be paralysed by Antiar. 
7- From all this it may be deduced, that the Antiar prin- 
cipally acts upon the muscular fibre and causes paralysis of it. 
So much for this time. My experiments with the Antiar 
upon warm-blooded animals have only begun, and I am not 
yet able to draw any conclusion from them. As soon as this 
will be possible I shall take the liberty to submit them to the 
Royal Society, together with the results of my experiments 
with the Upas teinte , which poison I had also the good fortune 
to obtain through the kindness of Sir Benjamin Brodie and 
Dr. Ilorsfield. With regard to the Antiar I may further add, 
that experiments made independently, and at the same time, 
by my friend Dr. Sharpey with this poison, have conducted 
to the same results as my own . — Proceedings of the Royal

One of us, pursuing his physiological researches on the 
phenomena of respiration, having met with results which it 
was impossible to interpret in the present state of the science, 
thought, rightly or wrongly, that a mutation of glucose by 
the lungs might account for them; but this was to admit
