Page 118 - ... these galls give rise to the females which live in the galls over winter and come out before the leaves appear in the spring. The galls just described are usually preceded -in the spring by a crop which affects the leaves only, and causes an enormous development of the midvein, often to the extent of an inch in diam.eter and an inch and a half in length. These latter galls are smooth and green but irregular in shape, succulent and a little harder than an unripe grape.
Page 434 - The anterior of these sections should pass in a line a little anterior to the anterior clinoid processes, and the posterior in a line through the posterior third of each mastoid process. By means of these two sections, the trumpetshaped extremity of each Eustachian tube, a portion of the mucous membrane of the fauces, and the whole of each petrous bone, together with the mastoid processes, can be taken out.
Page 436 - The cavities of the vestibule and cochlea are to be exposed, by removing a small portion of the upper wall of each. Before reaching the vestibule, the superior semicircular canal will be cut through and removed ; the membranous canal should be drawn out and inspected. As the cavities of the vestibule and cochlea are laid bare, it is desirable to see that the quantity of perilymph is natural, as well as its colour and consistence. The outer surface of the membranous labyrinth having been observed,...
Page 131 - In the microscope upon the table, the arrangement has been made; and when the ground is green, the waves of contraction which pass along each muscular fibre in various directions, are of a bright purple. In other parts of the field the complementary colours are reversed. There are few microscopic objects, that I am acquainted with, so beautiful as this.
Page 419 - ... larger than the right. They measure from an inch and a quarter to an inch and three-quarters in height, and about an inch and a quarter in width ; their thickness is from two to three lines. The weight of each suprarenal capsule in weight. the adult is from one to two drachms.
Page 88 - Ten grains of pure sulphate of iron are to be dissolved in an ounce of glycerine, or better, in a little distilled water and then mixed with glycerine, and thirty-two grains of ferridcyanide of potassium in another small proportion of water, and the solution mixed with glycerine. These two solutions are then gradually mixed together in a bottle, the iron solution being added to that of the ferridcyanide, and mixture ensured by frequent agitation.
Page 435 - ... its degree of tension, and the amount of motion possessed by the malleus when pressed upon by a fine point. The next step is to ascertain the condition of the guttural portion of the Eustachian tube, to lay open the cartilaginous tube with the scissors, and then to expose the cavity of the osseous portion by means of the cutting forceps. In doing this, the tensor tympani muscle is exposed ; its structure should be examined, and, if it has not a healthy appearance, portions of it should be submitted...
Page 435 - ... inwards than the basilar process of the occipital bone. These two sections are to be made with a saw, or with a chisel and hammer ; the apex of each petrous bone is then to be separated from the sphenoid and occipital bones, and each petrous bone, the outer ear and integument being detached and reflected downwards, is to be drawn outwards, taking care, by inserting the scalpel deeply, to remove as much of the soft parts as possible. With this second plan there is a difficulty in removing the...
Page 213 - If no soap had been used, this water could be examined in a long tube of thick glass, ten inches or more in length, and a quarter of an inch in internal diameter, permanently closed at one end with a circular piece of plate glass, and, when filled, covered over at the other with another glass. For examining solutions in such tubes a small pocket spectroscope, such as recently made for me by Mr. Browning, is extremely convenient, and suitable in every respect. If only two or three days old, the bands...
Page 266 - I can hardly think that in any given case the scientific evidence in favour of a particular blood stain being caused by human blood, will be of a kind that ought to be considered sufficiently conclusive to be adduced, for example, against a prisoner upon his trial.
