I hope that the many discoveries which I have made therein will in time prove useful. For instance, a fire may be made in some new stoves for warming, where the wood and coal which usually last a day will last six days, and will give out more heat. Vice-President Hjärne has approved of this in all its particulars, and if desired I can show the proof of it. The former of these treatises I handed in to-day to the Royal College of Mines.
"I have also written a little anatomy of our vital forces, which, I maintain, consist of tremulations. For this purpose I made myself thoroughly acquainted with the anatomy of the nerves and membranes; and I have proved the harmony which exists between that and the interesting geometry of tremulations—together with many other ideas in which I found that I agreed with those of Baglivius. The day before yesterday I handed them in to the Royal Medical College.
