The main differmose, it will be sem,are that in his series the left upper and right
lower were affected in about an equal number, the former slightly predominating, 68
whereas in mine these were reversed, and secondly in mine the proportion in which the
right middle lobe was involved was much higher.
As regards those which contained more than one focus there were 32 with two, 5 with
three, and the same nɛmber with several, The following was the distribution in eases

Of the five instances in which three foot were found in one case all were in the
upper lohe of the right lung; in another all were in the lower lobe of the left. er
the remaining three sil were in the right lung,viz.,one in the upper end two in the
lower in two cases, and the reverse of this,two in the upper and one in the lover
in ono.
Finally, in the five ences in which there were more than three feel the following
was the distributions All in the left lover lobe in onejin another, three foci were
present in the upper lobe of the left, and one in the upper of the rights in a third,
foot ware present in all lober except the right upper) in a fourth, in all woept the
left uppert in the fifth in all except the left lower.
Taking all the cases in which foci were found in the lungs,1,0, în 137 instancest The right upper lobe ms involved 42 times, the right lower 41, the left upper 32, the left lower 28, and the right middle 22. Thus, whereas Ghon found that the left upper was that most frequently involved after the right upper,in my series these Ware reversed; the right upper and right lower ware involved almost an equal number of times both in cases with a single foous and also when one considers all instances
in which focal lesions were present.
