The Anatomy of Ants. By Sir John Lubbock, Bart. 125 
XI. Intimate Structure of Bone. 
Results by means of continued researches, during which it had 
been found “ that in each of the four great classes of animals the 
bones present certain peculiarities in their form, which, when once 
an observer is conversant with them, would be enabled to satisfy 
himself as to the true affinities of doubtful specimens of organic 
remains ; ” that the “ same regularity of structure, the same me- 
thod of arrangement, has existed from the time when the surface 
of mu- planet was first inhabited by a vertebrate animal up to the 
present period.” Also, referring to recent investigations of the 
comparative size of the blood-disc in the “four great classes of 
animals, drawn up with much care and attention by Mr. Gul- 
liver,” suggesting that, as “ the bone-cells are the largest in the 
reptiles, the next largest in the mammal, and the smallest in the 
bird,” “ it would indeed be a curious result if it should ultimately 
turn out that the bone-cells of an animal are always in proportion 
to the size of the blood-discs ; ” and that “ should this mode of 
generalizing ultimately prove to be applicable to the bone-cells,” 
as to other tissues, “ we shall be able not only to determine the 
class of a fossil fragment, but to predict the size of the bfcod 
particles ; and when they are once known, the size and proportion 
of the other soft tissues may at once be inferred.” Read March 
and November, 1846. Yol. ii. p. 46. 
XII. Value of the Microscope in the determination of Minute Structures 
of a doubtful nature, as exemplified in the identification of 
Human Skin attached many centuries ago to the Doors of 
Churches. 
Showing that the presence of hair is essential for conclusive 
determination. Read April, 1848. Vol. ii. p. 151. 
XIII. Nature of Capillaries, and on the mode of arrangement of those in 
the Gills of Fishes. Read May, 1847. Vol. iii. p. 1. 
XIV. Vascularity of the Capsule of the Crystalline Lens, especially that 
of certain Reptilia. Read January, 1847. Vol. iii. p. 9. 
XV. Elastic Tissue in the Ligamentum Nuchse of the Giraffe. 
Describing certain “ transverse markings or stria:, somewhat 
resembling those of fibrillae of voluntary muscle in particular 
animals.” “ A striated form of elastic tissue has, I believe, never 
yet been noticed by any anatomist.” Read April, 1849. Vol. iii. 
p. 46. 
XVI. Scales of the Viviparous Blenny. 
“ I found that certain spots which had been described as circular 
depressions were in reality scales.” Read January, 1851. Vol. iii. 
p. 136. 
XVII. Structure of the Raphides of Cactus enneagonus. 
Including description of the artificial production of similar 
bodies in “ rice paper,” by his brother, Edwin Quekett. Read 
January, 1852. Quarterly Journal, No. 1, p. 20. 
XVIII. Presence of a Fungus and of Masses of Crystalline Matter in the 
Interior of a Living Oak Tree. 
Observations suggested by the sudden fall of a large limb of an 
oak in Marlborough Forest, in the presence of a picnic party, of 
which the writer was one. “ At one of the early meetings of this 
Society we had two papers on the ‘Decay of Fruit,’ in which 
Dr. Hassall showed that the rottenness of bruised or overripe 
apples, pears, &c., depended upon the growth of fungi. We have 
now another instance of it in the oak.” Read January, 1853. 
No. 3, p. 72. 
XIX. On the Microscopical characters of the insect White Wax of China. 
Pharmaceut. Jourm, xii., 1853, pp. 482-484.
