gâve you a more or lese complete pieture on the same basis as I computed
that of Dr. Leman, but am now glad to dive you, in accordance with your
request, the determinations as made upon the samples you submitted to me.
I will first give you the actual weights of the semples
which were received:
Bone

Trame
Kidney
1.83

Lungs
1.64

Liver

is as follows:
Bone

Kidney

Lungs
0028 n
