Shows a magnificent display of scintillations, showers of sparks, direct from the mineral Pitch blende, Radium, Polonium, Uranium, Thorium, or any radio-active substance, even a Welsbach mantle contains sufficient Thorium to excite the very sensitive screen of the Scintilloscope, which is far more sensitive than the Spinthariscope. The Scintilloscope rivals the most delicate Electroscope as a detector of Alpha rays.

The eye sees an inexhaustible shower of stars of white light, giving a very realistic idea of the ceaseless activity of these marvellous substances which are producing the terrific bombardment causing this beautiful display.

N two important features this magnificent work, of which the first volume is now before us, may lay claim to special preeminence. First, the illustrations, alike in number, size, truthfulness to nature, and artistic excellence, are unrivalled; and secondly, as regards the main and most important part of the subject, namely, the habits and local distribution of the various species, the work is in no sense a compilation, but the result of long and patient personal observation on the part of the author. Indeed, the only matter for regret connected with the work is that its price puts it out of the reach of a large percentage of field naturalists; bearing in mind, however, the style in which it is got up and the wealth of illustration, it is difficult to see how it could have been offered to the public at an appreciably lower figure.

As an author of a work like the present, Mr. Millais has one incomparable advantage over the great majority -if not, indeed, over all of his fellow-naturalists in this country, namely, that he is a great painter. In this double capacity of artist and naturalist he is consequently able to present the public not only with exquisite artistic pictures of the animals he describes, but also with portraits which emphasise and bring into prominence their special generic and specific characteristics. It is, indeed, this judicious blending of the artistic with the zoological aspect that confers on the coloured illustrations in this work such peculiar value. Too often in paintings of this description we find either zoological details more or less completely sacrificed to artistic effect or the former brought into undue prominence to the destruction of all that is really artistic and pleasing. In hitting off the happy medium between these extremes, Mr. Millais and the other two artists who have assisted in the work have been remarkably successful. In addition to the coloured pictures, there are a number of sketches, and in some cases photographs, showing the various animals in characteristic attitudes, in pursuit of their prey, &c., which illustrate their natural history almost without the necessity for letter-press. Nor is this all, for there are several sketches illustrative of the mammalian life of our island in prehistoric times; and although some of the details of form and colour assigned to certain of the extinct forms may be open to criticism, these certainly convey a good idea of the richness of this fauna as compared with that of the present day. No illustrations are given in the text of either skulls or teeth, which is perhaps somewhat to be regretted, as the latter receive mention in the text.

As regards the amount of time and labour the author has devoted to the work, it may be mentioned that, according to a statement in the preface, he made four successive expeditions, during as many years, in order

to acquire a full knowledge of the grey seal alone, and that the best part of five years has been spent on the task in general.

The present volume contains the preface and introduction to the entire work, together with the text and illustrations relating to the orders Chiroptera, Insectivora, and Carnivora exclusive of the Mustelidæ. The relegation of the latter to the second volume is rather a pity, as it involves the intercalation of the seals and walruses between the bears and the weasels, which somewhat mars the systematic arrangement. The author states, however, that he found it impossible to complete his account of the Mustelidæ in time for it to come in its proper place.

In his introduction the author takes a cursory survey of the history of the British Islands during the prehistoric and later Tertiary periods, and as he is not a professed paleontologist he may perhaps be allowed a little license here, especially as it does not affect the general subject of the work. The statement as to the occurrence of ungulates in the Cretaceous (perhaps due to the author having been misled by a certain South American writer) is, however, open to exception, while the alleged first appearance of marsupials and Insectivora at the same time is perhaps an error in the opposite direction. The assertion that many types of mammals have been but little altered since the (Lower) Eocene might also be modified.

While on the subject of errors, it may be mentioned that the author (and quite justifiably) is very much down" on other writers on British mammals for their various sins of omission and commission-whether trivial or otherwise. He must therefore take it in good part if similar slips of his own are brought to notice. For example, we fancy Sir Archibald Geikie will feel somewhat surprised to find himself described as a distinguished palæontologist and zoologist. Again, the initials of Dr. Smith Woodward are not A. B., neither is Dr. R. Ball (p. 238) the designation of the late director of the Dublin Museum, while Hermann, and not Herman, is the proper designation of the author of the name Sorex vulgaris (p. 141). Lack of classical knowledge seems to be implied in the translation of Chiroptera as hand-bearers (p. 12). More serious is the discrepancy between the number of teeth in Rhinolophus as given in the text (p. 23) and in the formula (p. 24), while another error of the same nature occurs on p. 143, where the number of premolars in the shrew is given as 2/4 instead of 4/2. Exception may also be taken to the statement (p. 230) that bears, as a whole, are a more primitive type than dogs, and the fact that the plate of the walrus is lettered Trichechus rosmarus while the creature is described in the text as Odobaenus rosmarus is another instance of want of care.

Reverting to the merits of the volume before us, attention may be directed to the value of the work accomplished by Mr. Millais in regard to the bats. Although the distinctive features of the various British representatives of the group can be gleaned by a careful study of technical treatises, the nature of the illustrations given in previous works on British mammals rendered it very hard for the amateur (to say
