Page 309 - ... their unimpregnated females. One of which is no sooner perceived, than they become so much enamoured of their fair and chaste relation, as absolutely to lose all kind of fear for their own personal safety, which, at other times, is effectually secured by the reiterated evolutions of their strong and rapid wings. So fearless indeed have I beheld them on these occasions, as to climb up and down the sides of the cage which contained the object of their eager pursuit, in exactly the same hurrying...

Page 325 - He made use, also, of small glass tubes, no thicker than a bristle, and drawn to a very fine point at one end, but thicker at the other. These were for the purpose of blowing up, and thus rendering visible, the smallest vessels which could be discovered by the microscope, to trace their courses and communications, or sometimes to inject them with coloured liquors.
Page 324 - ... beyond all parallel. The rich and velvet tints of the plumage of birds are not superior to what the curious observer may discover in a variety of Lepidoptera ; and those many-coloured eyes which deck so gloriously the peacock's tail are imitated with success by one of our most common butterflies.
Page 323 - indeed, appear to have been Nature's favourite productions, in which, to manifest her power and skill, she has combined and concentrated almost all that is either beautiful and graceful, interesting and alluring, or curious and singular, in every other class and order of her children.
