Página 433 - In the process of ossification there is a certain analogy between the spinal column and the cranium, but that analogy becomes weaker and weaker as we proceed towards the anterior end of the skull. Thus it may be right to say, that there is a primitive identity of structure between the spinal or vertebral column and the skull ; but it is no more true that the adult skull is a modified vertebral column, than it would be, to affirm that the vertebral column is a modified...
Página 76 - Urari may be paralysed by Antiar. 7. From all this it may be deduced, that the Antiar principally acts upon the muscular fibre and causes paralysis of it. So much for this time. My experiments with the Antiar upon warm-blooded animals have only begun, and I am not yet able to draw any conclusion from them. As soon as this will be possible...
Página 21 - It is well known that quinine and quinidin, under the continued effect of heat and dilute sulphuric acid, undergo a molecular change into quinicine, which M. Pasteur has asserted to be isomeric with the original alkaloids, but hitherto no complete analysis has been made of the metamorphosed alkaloids.
Página 75 - Autiar is introduced into a wound some time after the Urari. If we consider that, as I have shown (see Proceedings of the Royal Society, 1856, p. 201), the Urari only acts upon the terminations of the nerves in the muscles, and does not affect the irritability of the heart and muscles at all, we may conclude, that a poison, which, as the Antiar, is capable of paralysing the muscles after the Urari, has really a direct action upon the muscular fibre.
Página 68 - Pentasulphide of Potassium. : The following salts were affected in regard to their absorption of light, by adding water to their saturated solutions : — That these changes of colour are due to the action of the water, and not to any merely physical cause, is proved by the fact that alcohol does not occasion them. Quantitative experiments were instituted with acetate of copper and sulphocyanide of iron, to determine whether the effect of successive additions of water is in a decreasing ratio. It...

The increase over the last few months of high feeding, of pigs fed for curing, will contain considerably higher percentages of both fat and total dry substance, and lower ones of both nitrogenous compounds and mineral matter, than that of the more moderately fattened animal.
Página 237 - With regard to cylindrical internal flues, the experiments indicate the necessity of an important modification of the ordinary mode of construction, in order to render them secure at the high pressures to which they are now almost constantly subjected. If we take a boiler of the ordinary construction, 30 feet long, 7 feet in diameter, and with one or more flues 3 feet diameter, it will be found that the outer shell or...
Página 211 - that the conversion into ice is simultaneous" (and in a particular case referred to "identical") "with the formation of the blue bands; and that these bands are formed where the pressure is most intense, and where the differential motion of the parts is a maximum, that is, near the walls of a glacier.
Página 79 - ... theoretically demonstrated by my brother, is beautifully illustrated by Dr Tyndall's statement, that " the hazy surfaces produced by the compression of the mass were observed to be in a state of intense commotion, which followed closely upon the edge of the surface as it advanced through the solid. It is finally shown that these surfaces are due to the liquefaction of the ice in planes perpendicular to the pressure.
Página 649 - ... bodies. He has found that sounds which are faint, when heard by a hearing-tube applied directly to solid sounding bodies, become augmented when water is interposed between these bodies and the distal extremity of the hearing-tube. He has been able, by the employment of water, to hear the sound of a solid body, such as a table, which without this medium has been inaudible. Experiments have been made upon water in various amounts and in different conditions. Thus a very thin layer, a mere ring...
