My dear Sir
The simple substances known are fifty three to which if you add fluorine or the X which must stand in its place the number will be 541. I hope the progress of discovery will be rather to diminish than increase the number[.]
I am sorry I have not been able to reach your house yet[.] I was hoping for tomorrow night but it may not be. On Wednesday I have business I must attend to2[.]
