Hornets in Church. — Sunday, May 21st, was a very hot day, and 

 our morning congregation was rather disturbed by the appearance 

 of three large Hornets, which had doubtless made the church their 

 winter quarters. They were not very lively, and one was easily 

 killed by a choir-boy and another by a devout lady in the nave, while 

 the third was found dead in the church a few days later. A good 

 many queen "Wasps have been killed this spring, but the death of three 

 queen Hornets is a matter for congratulation, and I am keeping a 

 look-out for any other which may try to use our nest-boxes. — Julian 

 G. Tuck (Tostock Eectory, Bury St. Edmunds).

The Practical Principles of Plain Photo-Micrography. By George 

 West. Dundee : Campbell & Sons. 1916. 4s. 6d. net. 

 This small work of Mr. West, who is Lecturer in Botany at St. 

 Andrew's University, will commend itself to zoologists as well as 

 botanists, since the microscope and the delineation of what it shows 

 are equally necessary to them, and indeed, a couple of the photo- 

 graphic illustrations deal with subjects from the animal kingdom. 

 Mr. West's style is racy and incisive, and we are glad to see that, 

 while recommending a little-known and very simple system of camera- 

 less photo-micrography, he does not claim a universal superiority for 

 the photograph over the drawing; in fact, "Pen and pencil still 

 ahead " is one of his characteristic side-headings to the discussion of 

 this part of the subject. This exactly coincides with our own ex- 

 perience in the study of animals entire ; we have found the photo- 

 graph, though invaluable in some ways, tantalisingly lacking in detail, 

 and therefore often most unsuitable for students. Elsewhere we are 

 glad to see Mr. West rejecting the idea that nothing good in the way 

 of scientific instruments can be made outside Germany.
