general consideration of the normal development of the

infant, including its weight, muscular and nervous functions,the special senses, and dentition, is also given.The remainder of the book is devoted to a study of the

effects of errors of diet upon the digestion and nutrition ofthe infant. The various gastric and intestinal disorders aredescribed and the appropriate treatment is set forth.

Zymotic enteritis or infantile diarrhoea is dealt with at somelength. Dr. Vincent maintains that an essential factor inthe development of the disease is that the characteristic

properties of the milk should have been destroyed by heat,by preservatives, or by some other means. Descriptions ofinfantile atrophy, of rickets, and of scurvy are given, and theprevention and treatment of these conditions are discussed.

Dr. Vincent’s book is a thoughtful and practical work onthe subject with which it deals. It abounds in useful in-formation, and is obviously the outcome of special experience.Although some of his views will not find general acceptance,they demand consideration, since they are based upon apractical study of the principles involved. The book is

written in an easy and readable manner.

Transaet-ions of the Aonerican Dermatologioal Association atits Thirty-third Annllal Meeting held in Philadelphia, Juoe,1909. Official report of the Proceedings, by GROVER W.WENDE, M.D , secretary. Pp. 289.-Much valuable workhas been accomplished by American dermatologists, and someof the most interesting discoveries are usually reserved forthe annual meeting of the Dermatological Association. This

report of the proceedings of last year’s meeting, whichhas just come to hand, contains so much that is new and

important that it is difficult to pick out what is the

most valuable content of this interesting volume. Three

papers connected with psoriasis deserve mention. Dr.

S. Pollitser has written on the etiology of the disease,Dr. J. F. Schamberg on the parasitism of psoriasis,and Dr. W. F. Breakey on some unusual cases of

psoriasis. We agree with Dr. Pollitser’s conclusions that

psoriasis is most probably due to an external microbialinfective agent. Dr. J. A. Fordyce’s study on the lichengroup of skin diseases will well repay perusal, and theadmirable photoprints accompanying it can but enhance itsvalue. Dr. H. H. Whitehouse has applied the Wassermanntest in some cases of scleroderma, and he is inclined tosuggest, from the fact that in the six cases in which the testwas applied three gave a positive action, that syphilis maybe found to be an etiological factor in the production ofseleroderma. A very interesting paper is that written byDr. Douglas W. Montgomery and Dr. Howard Morrow onthe increase of certain contagions following the great fire inSan Francisco.

5.!. 3d. post free.-This book is an endeavour to bring beforethe public the value of certain services which the dog isfitted to perform for man. These include the tracking andarrest of criminals, a service in which dogs are now regularlyused in Germany, the searching out of wounded soldiers on

the field of battle, the carrying of messages and despatches,and the use of dogs as sentries and scouts. A chapter is

devoted to the watch-dog in the house, and some usefulinformation is given concerning the best methods of utilisinga dog for this purpose. The foot of the staircase in the hall,as being probably the centre of the house, is recom-

mended as the best position for the dog at night,

where he should be chained up beside a comfortablebed placed there for him. The use of dogs in war for

searching out the wounded seems justified by the results

which followed the use of some of Major Richardson’s dogsin the Russo-Japanese war. On this point Captain Persidskywrites as follows : "In finding the missing and wounded,with which the millet-fields are strewn, nothing has

succeeded like our pack of seven dogs. The English onesare especially intelligent. In our last engagement 23 menwere found in unsuspected places." Major Richardsonrecommends the collie and retriever as the breeds of dogsbest suited to ambulance work in temperate climates.He is making a trial of bloodhounds for hot countries.

Directions are given as to the training and equip-ment of dogs for ambulance work. The book concludes

with a chapter on scent, in which is contained an

account of some experiments performed by the author

and others in an attempt to elucidate the nature of

this faculty. Certain general conclusions are reached

in regard to the best condition of soil and atmospherefor the preservation of scent, but it has not been possible todraw any particular conclusions or to dogmatise, and thesubject remains much in the condition in which it was. The

book contains much useful information of the practical sort.The B1Ûlding and Care of the Budy. By CoLLrzLUS };I-.

Pp. 235. Price 2s. 6d.-This is a fair example of the innu-merable little works upon hygiene, both personal and

general, which have of late years been conspicuous featuresof the semi-medical press. It is apparently written for bothteachers and children, and not, we gather, for those of evena modest degree of education, for many words are givenphonetically, as well as spelt in the ordinary way-thus,contraction (k6n-trlk’shfin). The book commences with

simple lessons in physiology, and then goes on to treat offood, air, and the effects of pure and foul air on the health.Then follows a section on personal hygiene, common

accidents, and contagious diseases. There is a glossary atthe end. We cannot conscientiously say that the book is ofmuch value.

Observations on the Changes produced in the Bloodand Bone-marrow by Hemorrhage and Blood Destruction,C. Price Jones (London) gives a description and classifi-cation of the marrow cells of the rabbit, tracing boththe erythroblastic and leucoblastic series to a primitivelymphoid cell which, along with Buchanan, he derives bybudding from the giant cells. By emulsifying the freshmarrow in 10 per cent. neutral glycerine films may be made ;these are stained by Jenner’s stain, and show many detailswhich cannot be seen by section methods. The proportionsof the different kinds of cells may be determined by countingthese films. The marrow of rabbits, bled and killed aftervarious intervals and examined, shows that this method brings
