Page 661 - The limb consists of five divisions: the coxa or hip, the trochanter, the femur or thigh, the tibia or shank, and the tarsus or foot.
Page 127 - ... temple, like the blinders of a horse ; and next, having, by means of the joint at your chin, let down the whole apparatus, and uncovered your face, employ them in seizing any food that presented itself, and conveying it to your mouth. Yet this procedure is that adopted by the larva of the dragonfly, provided with this strange organ.
Page 127 - ... plates, which would project from each temple like the blinders of a horse ; and next having, by means of the joint at your chin, let down the whole apparatus, and uncovered your face, employ them in seizing any food that presented itself, and conveying it to your mouth.
Page 291 - I placed it upon my arm, where it kept pacing about for the space of more than an hour; when all its parts appearing consolidated and developed, and the animal perfect in beauty, I secured it, though not without great reluctance, for my cabinet — it being the only living specimen of this fine fly I had ever seen. To observe how gradual, and yet how rapid, was the development of the parts and organs, and particularly of the wings, and the perfect coming forth of the colours and spots, as the sun...
Page 209 - It is now wholly out of the skin, against one side of which it is supported, but yet at some distance from the leaf. The next step it must take is to climb up to the required height. For this purpose it repeats the same ingenious manoeuvre, making its cast-off skin serve as a sort of ladder, it successively with different segments seizes a higher and a higher portion, until in the end it reaches the summit, where with its tail it feels for the silken threads that are to support it.
Page 126 - ... so as to bend upwards again and fold over the face as high as the nose, concealing not only the chin and the first-mentioned elongation, but the mouth and part of the cheeks...
Page 281 - Attacus paphia when prepared to assume the imago, discharges from its mouth a large quantity of liquid, with which the upper end of the case is so perfectly softened as to enable the moth to work its way out in a very short space of time, an operation which, he says, is always performed in the night.
Page 127 - ... arm, catch the prey at which they aim by means of the mandibuliform plates, and then partly refold it so as to hold the prey to the mouth in a convenient position for the operation of the two pairs of jaws with which they are provided. Reaumur once found one of them thus holding and devouring a large tadpole; — a sufficient proof that Swammerdam was greatly deceived in imagining earth to be the food of animals so tremendously armed and fitted for carnivorous purposes.
Page 126 - In other larvae this part is usually small and inconspicuous, and serves merely for retaining the food and assisting in its deglutition, but in these it is by far the largest organ of the mouth, which, when closed, it entirely conceals, and it not only retains, but actually seizes the animal's prey by means of a very singular pair of jaws with which it is furnished;. Conceive your under lip (to have recourse...
Page 82 - I placed half a dozen of these boats upon the surface of a tumbler half-full of water : I then poured upon them a stream of that element from the mouth of a quart bottle held a foot above them. Yet after this treatment, which was so rough as actually to project one out of the glass, I found them floating as before upon their bottoms, and not a drop of water within their cavity*.
